 It is a fork of [mod_audio_stream](https://github.com/amigniter/mod_audio_stream), specifically adapted for streaming audio to OpenAI's Realtime API and playing the responses back to the user via FreeSWITCH and WebSocket.  
 
-The goal of **mod_openai_audio_stream** is to provide a simple, lightweight, yet effective module for streaming audio and receiving responses directly from OpenAI’s Realtime WebSocket into the call through FreeSWITCH. It uses [ixwebsocket](https://machinezone.github.io/IXWebSocket/), a C++ WebSocket library compiled as a static library.

 * Make sure to replace `sk-xxxxxxxxxxxxxxxxxx` with your actual OpenAI API key.
 * The dialplan answers the call and starts streaming audio to OpenAI's Realtime API using `uuid_openai_audio_stream`, so you can try it out and see the OpenAI events in the FreeSWITCH console within the `mod_openai_audio_stream::json` events and other module events.
