Usage (macOS)

Compatible with Mac OS Ventura

$ make install-deps
$ brew services start jack
$ brew services start pulseaudio
$ make
$ ./cli_amp

The amp settings (io devices, and dsp parameters) are defined in config.json

TODO

• automate end-to-end tests
• chain data structure for pedals
• wasm psychedelic visualizer and settings UI

troubleshooting

• sometimes audio on Mac OS is keeping data in the cache even though I am using the portaudio cleanup pattern
  • in this case $ sudo killall coreaudiod seems to help

notes to self

• initally used the portaudio build from host website, but this relies on "_Gestalt" in brew
• For VsCode, add /opt/homebrew/include to C/C++ Edit configurations (UI)

important dirs

• /opt/homebrew/Cellar: brew libs
• /opt/homebrew/lib: symlinks to brew .dylibs and .as:
• /opt/homebrew/include: symlinks to brew headers

some commands

• To start jack now and restart at login: brew services start jack
• Or, if you don't want/need a background service you can just run: /opt/homebrew/opt/jack/bin/jackd -X coremidi -d coreaudio
• To start pulseaudio now and restart at login: brew services start pulseaudio
• Or, if you don't want/need a background service you can just run: /opt/homebrew/opt/pulseaudio/bin/pulseaudio --exit-idle-time\=-1 --verbose
