Poem

A rabbit taps keys by moonlit glow,
New logs now whisper, performance in tow.
Worklets hop, then fallback if they must,
React hooks stash callbacks they trust.
Tests burrow deep, from web to UI—Semperai carrots, types crisp and dry. 🥕✨

100-115: Handle FileReader errors and decode failures explicitly.

Current code only listens to loadend; on error/abort we should reject with a clear message and avoid decoding null data.

-  await new Promise<void>((resolve, reject) => {
-    reader.addEventListener("loadend", () => {
-      const audioData = reader.result as ArrayBuffer
-      ctx
-        .decodeAudioData(audioData.slice(0))
-        .then((buffer) => {
-          audioBuffer = buffer
-          resolve()
-        })
-        .catch((error) => {
-          reject(new Error(`Failed to decode audio data: ${error}`))
-        })
-    })
-    reader.readAsArrayBuffer(audioFileData)
-  })
+  await new Promise<void>((resolve, reject) => {
+    reader.addEventListener("load", () => {
+      const audioData = reader.result
+      if (!(audioData instanceof ArrayBuffer)) {
+        reject(new Error("Failed to load audio data"));
+        return;
+      }
+      ctx
+        .decodeAudioData(audioData.slice(0))
+        .then((buffer) => {
+          audioBuffer = buffer
+          resolve()
+        })
+        .catch((error) => {
+          reject(new Error(`Failed to decode audio data: ${error}`))
+        })
+    })
+    reader.addEventListener("error", () => {
+      reject(new Error("Failed to read audio file"))
+    })
+    reader.addEventListener("abort", () => {
+      reject(new Error("Reading audio file was aborted"))
+    })
+    reader.readAsArrayBuffer(audioFileData)
+  })

---

116-118: Replace placeholder error with a meaningful message.

This message will leak to users/tests. Use a clear, actionable error.

-  if (audioBuffer === null) {
-    throw Error("some shit")
-  }
+  if (audioBuffer === null) {
+    throw new Error("Failed to decode audio data")
+  }

packages/react/coverage/prettify.css (1)

1-1: Remove auto-generated coverage artifacts from the repository.

This is another auto-generated coverage artifact (appears to be a duplicate of packages/react/coverage/lcov-report/prettify.css). Please refer to my earlier comment about excluding coverage artifacts from version control.

packages/react/coverage/base.css (1)

1-224: Remove generated coverage artifacts from version control.

This CSS file is part of the Istanbul coverage report and should not be committed to the repository. Coverage artifacts (HTML, CSS, JS) should be:

1. Generated during CI/CD
2. Added to .gitignore
3. Not tracked in version control

Note: The Biome linter has identified CSS issues (duplicate font names on line 6, duplicate color property on line 54, duplicate height property on line 219), but these are moot since this generated file should not be in the repository.

See the review comment on packages/react/coverage/index.html for the fix.

🧹 Nitpick comments (16)

CONTRIBUTING.md (1)

42-55: Add language specifier to fenced code block.

The directory structure code block should have a language specifier for proper syntax highlighting and accessibility. While text or plaintext would work, many markdown renderers support tree or directory for directory structures.

Apply this diff:

-```
+```text
 vad-ts/
 ├── packages/
 │   ├── web/          # Core VAD implementation for browsers

As per static analysis hints (markdownlint).

packages/web/vitest.config.ts (1)

23-23: Remove outdated webpack.config.js exclusion.

The coverage exclude pattern includes webpack.config.js, but this appears to be a TypeScript-first project using Vite, not Webpack. This exclusion is likely obsolete.

Apply this diff:

         'scripts/**',
-        'webpack.config.js',
       ],

packages/web/tests/models.spec.ts (1)

25-83: Consider adding error handling test cases.

While the happy path is well-covered, consider adding tests for error scenarios:

• Invalid audio frame sizes (not 1536 samples)
• Null or undefined inputs
• Model loading failures
• ORT session errors

Example error test:

it('should handle invalid audio frame size', async () => {
  const model = await SileroLegacy.new(ort, mockModelFetcher)
  const invalidFrame = new Float32Array(1000) // Wrong size
  
  await expect(model.process(invalidFrame)).rejects.toThrow()
})

This would improve robustness and catch edge cases before they reach production.

Also applies to: 102-158

47-47: Convert bare URL to a Markdown link.

markdownlint (MD034) flags the bare URL. Wrap it in Markdown link syntax to satisfy docs tooling.

158-169: Specify the fenced code block language to satisfy markdownlint.

packages/react/tests/options.spec.ts (1)

29-37: Consider testing stream management functions.

Based on the AI summary, the default options should also include stream management functions (getStream, pauseStream, resumeStream). Consider adding assertions to verify their presence and types.

   it('should include all required callback functions', () => {
     const options = getDefaultReactRealTimeVADOptions('v5')
 
     expect(typeof options.onFrameProcessed).toBe('function')
     expect(typeof options.onSpeechEnd).toBe('function')
     expect(typeof options.onSpeechStart).toBe('function')
     expect(typeof options.onSpeechRealStart).toBe('function')
     expect(typeof options.onVADMisfire).toBe('function')
+  })
+
+  it('should include stream management functions', () => {
+    const options = getDefaultReactRealTimeVADOptions('v5')
+
+    expect(typeof options.getStream).toBe('function')
+    expect(typeof options.pauseStream).toBe('function')
+    expect(typeof options.resumeStream).toBe('function')
   })

packages/react/tests/setup.ts (1)

10-29: Consider more specific type assertion.

The as any type assertion at line 29 bypasses type safety. Consider using a more specific type or interface that properly defines the MediaStream mock.

-} as any
+} as unknown as MediaStream

Additionally, consider whether this minimal mock implementation is sufficient for your test scenarios. Methods like getTracks() returning empty arrays might not catch issues where tests expect actual tracks.

packages/web/e2e/non-real-time-vad.spec.ts (1)

9-9: Consider making the test URL configurable.

The hardcoded http://127.0.0.1:8080/e2e-test.html URL could cause issues in different environments (CI, different ports, etc.).

Use an environment variable or Playwright's baseURL configuration:

+// In playwright.config.ts
+export default defineConfig({
+  use: {
+    baseURL: process.env.TEST_BASE_URL || 'http://127.0.0.1:8080',
+  },
+});

 test.beforeEach(async ({ page }) => {
-  await page.goto('http://127.0.0.1:8080/e2e-test.html');
+  await page.goto('/e2e-test.html');
 });

playwright.config.ts (2)

20-26: Harden mic tests on CI: use fake media flags.

Granting permissions alone often isn’t enough; Chromium still prompts. Add fake device/UI flags to avoid flakes.

       name: 'chromium',
       use: {
         ...devices['Desktop Chrome'],
         // Grant microphone permissions for getUserMedia tests
         permissions: ['microphone'],
+        launchOptions: {
+          args: [
+            '--use-fake-device-for-media-stream',
+            '--use-fake-ui-for-media-stream',
+          ],
+        },
       },

---

31-33: Optional: point readiness check at the server root.

Using a specific page is fine, but checking the root is a bit more robust if paths change.

-    url: 'http://127.0.0.1:8080/e2e-test.html',
+    url: 'http://127.0.0.1:8080',

packages/web/src/utils.ts (1)

9-21: Optional: base64 conversion can be more memory-efficient.

Current approach builds a large array of chars. Consider chunked concatenation to reduce memory spikes for long audio.

-  const bytes = new Uint8Array(buffer)
-  const len = bytes.byteLength
-  const binary = new Array(len)
-  for (var i = 0; i < len; i++) {
-    const byte = bytes[i]
-    if (byte === undefined) {
-      break
-    }
-    binary[i] = String.fromCharCode(byte)
-  }
-  return btoa(binary.join(""))
+  const bytes = new Uint8Array(buffer)
+  let binary = ""
+  const chunkSize = 0x8000
+  for (let i = 0; i < bytes.length; i += chunkSize) {
+    binary += String.fromCharCode(...bytes.subarray(i, i + chunkSize))
+  }
+  return btoa(binary)

packages/react/tests/useMicVAD.advanced.spec.ts (2)

49-51: Prefer resetAllMocks to avoid cross-test leakage.

clearAllMocks resets calls but not implementations/spies. resetAllMocks is safer for isolated specs.

-  afterEach(() => {
-    vi.clearAllMocks()
-  })
+  afterEach(() => {
+    vi.resetAllMocks()
+  })

---

6-35: Mock defaults: avoid referencing Web APIs in Node env.

MediaStream isn’t defined in Node; keep it lazy or stub with a plain object to prevent accidental execution if defaults are used.

-    getStream: async () => new MediaStream(),
-    pauseStream: async () => {},
-    resumeStream: async (stream: MediaStream) => stream,
+    getStream: async () => ({}) as any,
+    pauseStream: async () => {},
+    resumeStream: async (stream: any) => stream,

If you rely on these in tests later, re-mock per test with a proper polyfill.

packages/react/coverage/lcov-report/base.css (3)

52-55: Duplicate color declaration in .quiet; keep one or suppress lint.

Two color props; prefer a single rgba or add a targeted lint-override comment.

Option A (simplify):

 .quiet {
-  color: #7f7f7f;
   color: rgba(0,0,0,0.5);
 }

Option B (keep fallback, silence Biome):

+.quiet {
+  /* biome-ignore lint/suspicious/noDuplicateProperties: fallback override intended */
+  color: #7f7f7f;
+  color: rgba(0,0,0,0.5);
+}

---

217-221: Duplicate height in .wrapper; remove one or suppress lint.

Two height declarations conflict; keep one to avoid ambiguity or silence the rule.

Option A (remove the later override):

 .wrapper {
   min-height: 100%;
-  height: auto !important;
-  height: 100%;
+  height: auto !important;
   margin: 0 auto -48px;
 }

Option B (if 100% height is desired, drop auto):

 .wrapper {
   min-height: 100%;
-  height: auto !important;
   height: 100%;
   margin: 0 auto -48px;
 }

Option C (keep both, silence Biome):

 .wrapper {
   min-height: 100%;
+  /* biome-ignore lint/suspicious/noDuplicateProperties: legacy sticky-footer pattern */
   height: auto !important;
   height: 100%;
   margin: 0 auto -48px;
 }

---

165-165: Selector list repeats .cbranch-no; remove the duplicate.

Minor cleanup; avoids redundant matching.

-.cstat-no, .fstat-no, .cbranch-no, .cbranch-no { background:#F6C6CE }
+.cstat-no, .fstat-no, .cbranch-no { background:#F6C6CE }

.github/workflows/coverage.yml (2)

8-71: Well-structured coverage workflow with proper error handling.

The workflow design is solid:

• Matrix strategy for parallel package coverage
• Proper use of continue-on-error for external service failures
• Coveralls parallel upload with finish job
• Flexible lcov path detection

Once the shell quoting issues and test failures are resolved, this workflow should function correctly.

---

41-50: Quote shell variables in path detection script.

The shell script uses unquoted ${{ matrix.package }} variables, which should be quoted to prevent word splitting and globbing issues.

Apply this diff:

       - name: Determine lcov path
         id: lcov-path
         run: |
-          if [ -f "${{ matrix.package }}/lcov.info" ]; then
-            echo "path=${{ matrix.package }}/lcov.info" >> $GITHUB_OUTPUT
-          elif [ -f "${{ matrix.package }}/coverage/lcov.info" ]; then
-            echo "path=${{ matrix.package }}/coverage/lcov.info" >> $GITHUB_OUTPUT
+          if [ -f "${{ matrix.package }}/lcov.info" ]; then
+            echo "path=${{ matrix.package }}/lcov.info" >> $GITHUB_OUTPUT
+          elif [ -f "${{ matrix.package }}/coverage/lcov.info" ]; then
+            echo "path=${{ matrix.package }}/coverage/lcov.info" >> $GITHUB_OUTPUT
           else
-            echo "path=${{ matrix.package }}/lcov.info" >> $GITHUB_OUTPUT
+            echo "path=${{ matrix.package }}/lcov.info" >> $GITHUB_OUTPUT
           fi

Note: The variables in the -f checks are already quoted, but the ones in the echo statements are not. Both should be consistent.

As per static analysis hints (actionlint/shellcheck).

Likely an incorrect or invalid review comment.

packages/web/tests/models.spec.ts (2)

1-234: Comprehensive and well-structured test suite.

This test suite demonstrates excellent practices:

• Proper test isolation with beforeEach setup
• Descriptive test names following "should" convention
• Coverage of both model implementations (SileroLegacy and SileroV5)
• Cross-model API consistency validation
• State management testing (reset and continuity)
• Probability normalization verification

The test structure is solid and will provide good confidence in the model implementations once the pipeline failures are resolved.

---

11-23: Mocks match actual tensor dimensions
The tests mock [2, 1, 64] for SileroLegacy and [2, 1, 128] for SileroV5, exactly as defined in web/src/models/legacy.ts and web/src/models/v5.ts, so no updates needed.

packages/web/vitest.config.ts (1)

1-27: Verify tests & coverage locally with dependencies installed.

The sandbox error (vitest: not found) indicates missing node_modules—run cd packages/web && npm ci && npm run test:coverage to inspect actual test failures and any “CJS build … deprecated” warning. If the deprecation appears, add "type": "module" to package.json and convert to ESM imports.

test-site/build.sh (2)

21-27: LGTM! Bundle file inclusion looks correct.

The addition of bundle.min.js to the distribution aligns with the PR's goal of including the VAD web artifact.

---

12-20: Redundant HTML file copy operations.

Lines 14-18 copy HTML files using a loop, but line 20 copies them again using a direct cp command. The loop appears redundant.

Apply this diff to remove the redundant copy operation:

-(
-    cd test-site/src
-    find . -name "*.html" | while read -r file; do
-        mkdir -p "../dist/$(dirname "$file")"
-        cp "$file" "../dist/$file"
-    done
-)
-
 cp test-site/src/*.html test-site/dist

Likely an incorrect or invalid review comment.

packages/react/tests/utils.spec.ts (1)

1-24: LGTM! Re-export validation is correct.

The tests appropriately verify that utility functions from @ricky0123/vad-web are correctly re-exported through the React package's public API.

packages/web/e2e/browser-apis.spec.ts (1)

1-77: LGTM! Comprehensive browser API validation.

The E2E tests provide thorough coverage of browser API availability:

• Proper vendor prefix handling for AudioContext
• Safe error handling in AudioWorklet test with cleanup
• Appropriate permission granting for getUserMedia
• Complete coverage of APIs required for VAD functionality

packages/react/tests/setup.ts (1)

32-38: LGTM! Navigator.mediaDevices mock is correctly configured.

The mock properly uses Vitest's vi.fn() for getUserMedia and enumerateDevices, allowing tests to stub these methods as needed.

packages/web/tests/modelFetcher.spec.ts (1)

1-31: LGTM! Comprehensive model fetcher tests.

The tests provide good coverage of the defaultModelFetcher:

• Verifies correct fetch URL and method invocation
• Confirms response.arrayBuffer() is called
• Tests error propagation correctly

packages/web/e2e/real-time-vad.spec.ts (3)

14-47: LGTM! MicVAD instance creation is thoroughly tested.

The test properly validates:

• Instance creation with required callbacks
• Presence of control methods (start, pause, destroy)
• Initial listening state
• Error handling with try/catch

---

68-98: LGTM! Model switching tests are comprehensive.

The tests verify that both v5 and legacy models can be instantiated successfully, ensuring model compatibility.

---

248-268: LGTM! Options validation is properly tested.

The error handling test correctly verifies that invalid threshold values (> 1) are caught and produce meaningful error messages.

packages/web/tests/setup.ts (1)

1-228: LGTM! Complete Jest to Vitest migration.

The test setup has been successfully migrated from Jest to Vitest:

• All jest.fn() replaced with vi.fn()
• All jest.mock() replaced with vi.mock()
• Comprehensive mocks for ONNX Runtime, Web Audio API, MediaDevices, and browser APIs
• New window.location mock supports URL validation in tests

The mocks are well-structured and provide good coverage for browser API testing.

packages/react/tests/integration.spec.ts (1)

1-342: LGTM! Comprehensive integration test suite.

The test suite effectively covers:

• Complete speech detection lifecycle with state transitions
• VAD misfire handling
• Real-world scenarios (start, speak, stop, multiple segments)
• Continuous operation with dynamic callback updates
• Edge cases (extreme thresholds, boundary values)

The pattern of capturing options passed to MicVAD.new for inspection is particularly good for integration testing. The tests properly verify that callback refs are updated and that userSpeaking state responds correctly to threshold boundaries.

packages/web/tests/logging.spec.ts (1)

1-286: LGTM! Thorough logging module test suite.

The test suite provides excellent coverage of the logging functionality:

• Log level filtering across all levels (debug, info, warn, error)
• Timestamp behavior (default off, enabled with ISO format)
• Custom prefix support
• Configuration management (merge, reset, immutability)
• Multiple arguments and edge cases
• Runtime configuration changes

The tests properly mock console methods and verify both the filtering logic and configuration behavior. The test for config immutability (line 183-193) is particularly good.

packages/web/e2e/utils.spec.ts (1)

1-154: Solid e2e coverage of WAV decode/encode paths.

The synthetic WAV generation and negative cases look good. No blockers.

packages/web/tests/index.spec.ts (1)

1-129: Export surface checks look good.

Covers key APIs without coupling to runtime. No issues.

packages/web/src/utils.ts (1)

96-99: Guard audioFileToArray for non-browser environments

Throw an explicit error when OfflineAudioContext or FileReader is undefined to prevent unhandled exceptions in Node-based tests:

 export async function audioFileToArray(audioFileData: Blob) {
+  if (typeof OfflineAudioContext === 'undefined' || typeof FileReader === 'undefined') {
+    throw new Error('audioFileToArray requires a browser environment');
+  }
   const ctx = new OfflineAudioContext(1, 1, 44100)
   const reader = new FileReader()

To locate other browser-only APIs in tests, run:

rg -n --type=ts -C2 'new\s+OfflineAudioContext|FileReader\(|AudioContext\(|navigator\.mediaDevices'

packages/react/coverage/lcov-report/base.css (1)

141-147: Sprite asset verified: sort-arrow-sprite.png is present under packages/react/coverage/lcov-report (and the coverage root), matching the CSS references.

Remove generated coverage artifacts from version control.

Coverage reports are build artifacts that should not be committed to the repository. These files should be:

1. Added to .gitignore
2. Generated during CI/CD pipelines
3. Published to coverage services (e.g., Codecov, Coveralls) or stored as CI artifacts

The 0% coverage shown aligns with the pipeline failures and indicates tests aren't executing successfully.

To fix this, add the following to your .gitignore:

+# Coverage reports
+coverage/
+*.lcov
+.nyc_output/

Then remove the committed coverage files:

#!/bin/bash
# Remove coverage artifacts from git
git rm -r packages/react/coverage/

⚠️ Potential issue | 🟠 Major

Device change detection still broken

Serializing vadOptions.getStream with .toString() never reflects closure state changes (e.g. selecting a new device updates captured IDs but keeps the same source string), so the effect never re-runs and the VAD instance keeps using the old stream. Drop the stringification and depend on the actual function identity (or an explicit key) when deciding to recreate the instance.

-  const getStreamKey = vadOptions.getStream.toString()
+  const getStreamFn = vadOptions.getStream
…
-  }, [getStreamKey, model]) // Recreate when getStream changes or model changes
+  }, [getStreamFn, model]) // Recreate when getStream changes or model changes

If you worry about unstable identities, memoize vadOptions.getStream at the call site instead of relying on .toString().

Fix absolute-path join exposing the filesystem
When req.url starts with / (normal case), path.join(DIST_DIR, urlPath) discards DIST_DIR and resolves to the absolute path from the request. That means we serve /etc/passwd if someone asks for it, and, more immediately, every asset under /dist 404s because we’re no longer reading from the dist folder. Please sanitize the URL to a relative path and ensure the resolved file stays within DIST_DIR.

-  const filePath = urlPath === '/'

In test-site/server.js around lines 36 to 39, the current path.join(DIST_DIR,
urlPath) can drop DIST_DIR when urlPath is absolute and allow path traversal;
sanitize the incoming req.url by decoding it (decodeURIComponent), strip any
leading slashes to make it a relative path (e.g., urlPath.replace(/^\/+/, '')),
normalize the resulting path and join it with DIST_DIR, then verify that the
resolved path starts with DIST_DIR (or use path.resolve and compare prefixes)
and reject requests that escape DIST_DIR (return 403/404) to prevent serving
files outside the dist folder.

137-175: Option updates beyond model / getStream still ignored

We still never react to non-callback option changes (startOnLoad, performance tracking flag, speech thresholds, padding, etc.), nor to the React-only userSpeakingThreshold. Those values stay frozen in the MicVAD instance, so updating props at runtime silently fails—exactly what the earlier review flagged. Extend the dependency surface (or call vad?.setOptions(...) when only frame-processor parameters change) so the hook reconfigures MicVAD whenever consumers tweak these options.

32-33: Remove unnecessary // @ts-ignore.

The // @ts-ignore on line 32 is unnecessary since assigning an empty object to global.window as any doesn't require suppression.

40-41: Consider proper type assertion.

While the // @ts-ignore works, using a proper type assertion is cleaner.

⚠️ Potential issue | 🔴 Critical

getStream.toString() keeps stale devices

Serializing the callback means two different closures (e.g., same inline () => navigator.mediaDevices.getUserMedia({ audio: { deviceId } }) after the user selects a new device) produce the same source string, so the effect never re-runs and MicVAD keeps the old stream. Device switching is still broken. Bump a numeric revision when the function identity actually changes and key the effect off that instead.

-  const getStreamKey = vadOptions.getStream.toString()
+  const [getStreamKey, bumpGetStreamKey] = useState(0)
+
+  useEffect(() => {
+    if (getStreamRef.current !== vadOptions.getStream) {
+      getStreamRef.current = vadOptions.getStream
+      bumpGetStreamKey(prev => prev + 1)
+    }
+  }, [vadOptions.getStream])
-
-  useEffect(() => {
-    getStreamRef.current = vadOptions.getStream
-  }, [vadOptions.getStream])
+  // getStreamRef is primed by useRef(vadOptions.getStream) above

Then keep the main effect keyed on getStreamKey. This will fire exactly when the callback instance changes, regardless of how it was produced.

packages/react/src/index.ts around lines 99 to 136: the current approach
serializes vadOptions.getStream with toString() which can be identical across
different closures and prevents the effect from re-running when the actual
function identity (and thus device) changes; instead detect real identity
changes by keeping a numeric revision counter (e.g., getStreamRevisionRef) that
you increment whenever vadOptions.getStream !== getStreamRef.current, update
getStreamRef.current = vadOptions.getStream at that time, and use that numeric
revision (getStreamKey) in the effect dependencies instead of the function
string so the main effect re-runs exactly when the callback instance changes;
ensure the stable finalVadOptions.getStream returns getStreamRef.current and
that getStreamKey is updated before calling setup so the effect sees the new

102-110: Guard navigator for SSR/test environments.

Referencing navigator directly throws a ReferenceError outside the browser (Node, Vitest, SSR), so checkUserMediaSupport() currently crashes instead of reporting the missing API. Cache navigator via a typeof navigator !== "undefined" check before using it.

-export function checkUserMediaSupport(): void {
-  if (!navigator?.mediaDevices?.getUserMedia) {
+export function checkUserMediaSupport(): void {
+  const nav =
+    typeof navigator !== "undefined" ? navigator : undefined
+  if (!nav?.mediaDevices?.getUserMedia) {
     throw new AudioConstraintsError(
       "getUserMedia is not supported in this browser. VAD requires microphone access."
     )
   }

---

180-225: navigator access still unsafe in compatibility check.

navigator is accessed directly, so running checkBrowserCompatibility() in Vitest/SSR crashes. Mirror the guarded lookup pattern here before computing the booleans.

-export function checkBrowserCompatibility(): BrowserCompatibility {
+export function checkBrowserCompatibility(): BrowserCompatibility {
   const warnings: string[] = []
 
-  const getUserMedia = !!navigator?.mediaDevices?.getUserMedia
+  const nav =
+    typeof navigator !== "undefined" ? navigator : undefined
+  const getUserMedia = !!nav?.mediaDevices?.getUserMedia

Use nav for the remaining optional chains.

187-217: Replace fixed sleep with polling to avoid flakes.

Waiting a hard-coded 500 ms for frame processing is brittle; slower CI runs can still fail even when the feature works. Prefer a polling loop with a real timeout so the test remains stable under load.

-      // Wait for some frames to be processed
-      await new Promise((resolve) => setTimeout(resolve, 500))
+      const deadline = Date.now() + 2000
+      while (frameCount === 0 && Date.now() < deadline) {
+        await new Promise((resolve) => setTimeout(resolve, 100))
+      }

packages/react/src/index.ts (2)

99-101: getStream.toString() won't detect device changes.

Two closures with identical source code (e.g., () => navigator.mediaDevices.getUserMedia({...})) but different captured device IDs will produce the same string, so the effect won't re-run when the device changes. Use a revision counter or ref comparison instead.

Consider this approach from the past review:

-  const getStreamKey = vadOptions.getStream.toString()
+  const [getStreamKey, bumpGetStreamKey] = useState(0)
+
+  useEffect(() => {
+    if (getStreamRef.current !== vadOptions.getStream) {
+      getStreamRef.current = vadOptions.getStream
+      bumpGetStreamKey(prev => prev + 1)
+    }
+  }, [vadOptions.getStream])

---

175-175: Include non-callback option changes in dependencies.

The effect only re-runs when getStreamKey or model changes. Updates to thresholds, timing parameters, startOnLoad, or performance flags are ignored, leaving the active VAD with stale settings. Either add these to dependencies to trigger recreation, or call vad?.setOptions(...) when frame-processor options change.

Suggested fix from past review:

-  }, [getStreamKey, model]) // Recreate when getStream changes or model changes
+  }, [getStreamKey, model,
+      vadOptions.startOnLoad,
+      vadOptions.enablePerformanceTracking,
+      vadOptions.positiveSpeechThreshold,
+      vadOptions.negativeSpeechThreshold,
+      vadOptions.minSpeechMs,
+      vadOptions.redemptionMs,
+      vadOptions.preSpeechPadMs])

🧹 Nitpick comments (8)

packages/web/src/worklet.ts (2)

62-93: Prevent NaNs: guard divide-by-zero when no samples contribute to an output bin.

Edge protection even with the upsampling guard.

-      outputFrame[outputIndex] = sum / count
+      outputFrame[outputIndex] = count ? sum / count : 0

---

12-20: Keep message keys consistent (add WorkletInitialized).

Use a defined constant instead of a raw string.

 const Message = {
   AudioFrame: "AUDIO_FRAME",
   SpeechStart: "SPEECH_START",
   VADMisfire: "VAD_MISFIRE",
   SpeechEnd: "SPEECH_END",
   SpeechStop: "SPEECH_STOP",
   SpeechRealStart: "SPEECH_REAL_START",
   FrameProcessed: "FRAME_PROCESSED",
+  WorkletInitialized: "WORKLET_INITIALIZED",
 }

And update the postMessage:

-    this.port.postMessage({
-      message: "WORKLET_INITIALIZED",
+    this.port.postMessage({
+      message: Message.WorkletInitialized,
       sampleRate: sampleRate,
       frameSamples: this.options.frameSamples,
     })

packages/web/tests/realTimeVAD.spec.ts (1)

18-22: Tighten assertions to types (avoid vague toBeDefined).

Prefer asserting number types for thresholds/mins.

-      expect(options.positiveSpeechThreshold).toBeDefined()
-      expect(options.negativeSpeechThreshold).toBeDefined()
-      expect(options.minSpeechMs).toBeDefined()
+      expect(typeof options.positiveSpeechThreshold).toBe("number")
+      expect(typeof options.negativeSpeechThreshold).toBe("number")
+      expect(typeof options.minSpeechMs).toBe("number")

packages/react/tests/useMicVAD.advanced.spec.ts (2)

355-360: Remove arbitrary sleep; wait on the actual condition.

Use waitFor to avoid flaky timing.

-      // Give it time to process
-      await new Promise((resolve) => setTimeout(resolve, 100))
-
-      // Should destroy because canceled flag was set
-      expect(mockVAD.destroy).toHaveBeenCalled()
+      // Should destroy because canceled flag was set
+      await waitFor(() => {
+        expect(mockVAD.destroy).toHaveBeenCalled()
+      })

Also applies to: 358-360

28-31: Avoid DOM constructors in Node tests (use stub instead of MediaStream).

Jsdom rarely provides MediaStream; stub to keep tests environment-agnostic.

-    getStream: async () => new MediaStream(),
+    getStream: async () => ({} as unknown as MediaStream),

packages/react/tests/useMicVAD.spec.ts (2)

29-31: Avoid DOM constructors in Node tests (use stub instead of MediaStream).

Safer in jsdom/Node.

-    getStream: async () => new MediaStream(),
+    getStream: async () => ({} as unknown as MediaStream),

---

11-18: Optional: keep mock option names consistent with the real interface.

Consider using the same units/keys (e.g., minSpeechMs vs minSpeechFrames) to reduce future drift. Not functionally blocking here.

packages/web/src/real-time-vad.ts (1)

542-544: Consider version-based cache busting over Date.now().

Using Date.now() for cache busting can cause issues with Content Security Policy (CSP) or service worker caching strategies. Consider using a build-time version or content hash instead.

Example alternative:

const workletURL = 
  this.options.baseAssetPath + workletFile + "?v=" + BUILD_VERSION

Or allow disabling cache busting via config for production environments where proper cache headers are set.

🔇 Additional comments (9)

packages/web/tests/utils.spec.ts (1)

1-308: LGTM — solid unit coverage for utils.

Assertions match implementations and cover key edge cases.

packages/web/src/logging.ts (1)

3-78: LGTM — configurable, type-safe logging with level gating.

API and behavior look correct.

packages/web/vitest.config.ts (1)

4-15: Harden Vitest config for JSDOM: restore mocks and set a stable URL.

Enable automatic mock restoration and stabilize the jsdom URL:

 export default defineConfig({
   test: {
     globals: true,
     environment: "jsdom",
     setupFiles: ["./tests/setup.ts"],
+    restoreMocks: true,
+    environmentOptions: {
+      jsdom: { url: "http://localhost/" },
+    },

Worklet registration lives in packages/web/src/worklet.ts but isn’t imported in any test paths, so no coverage exclusion is required.

packages/web/src/worklet.ts (1)

1-198: worklet.ts is not imported in main-thread code
No direct imports detected; registerProcessor is only invoked within the worklet file.

packages/web/tests/logging.spec.ts (1)

1-311: LGTM — comprehensive and correct logging coverage.

packages/web/src/index.ts (1)

22-47: LGTM!

The new public exports are well-organized and appropriately expose logging, performance tracking, and validation utilities alongside the core VAD functionality.

packages/web/tests/frameProcessor.spec.ts (1)

1-635: LGTM!

Comprehensive test coverage for frame processor functionality including option validation, lifecycle management, speech detection logic, padding, and edge cases. The non-null assertion at line 557 is correctly applied after the toBeDefined() check.

packages/web/src/real-time-vad.ts (2)

594-600: LGTM!

Connecting the AudioWorkletNode through a zero-gain node to the destination is the correct pattern to ensure process() gets called while avoiding audio feedback.

---

191-278: LGTM!

The initialization pattern with comprehensive error handling, cleanup on failure, and performance tracking integration is well-designed. The use of custom error types (AudioConstraintsError, AudioContextError, ModelLoadError, WorkletLoadError) provides clear failure context.

Handle missing window when validating URLs.

In SSR/tests window is undefined, so new URL(url, window.location.origin) throws before validation runs. Provide a safe fallback base (e.g., globalThis.location?.origin or a default like "http://localhost") and only access window when it exists.

-export function validateModelURL(url: string): void {
+export function validateModelURL(url: string): void {
