I'm here to help! To capture and play a live audio stream in real-time using VAPI, you would typically use the Vapi Client SDKs which handle audio streaming automatically. Since you're looking for documentation on handling the WebSocket audio stream, here's a general approach you can take:
1. **Initialize the Vapi Client SDK**: Depending on your platform (Web or iOS), you need to initialize the SDK first. This will set up the necessary configurations for audio streaming.
2. **Start a Call**: Use the SDK's interface to start a call. This will open a WebSocket connection and start streaming audio.
3. **Handle Incoming Audio**: The SDK will provide callbacks or events for incoming audio data. You can use these to process or play the audio in real-time.
4. **Send Audio**: If you want to send audio back, you can use the provided methods in the SDK to capture audio from the microphone and send it over the WebSocket connection.
For specific documentation, you can visit the GitHub repositories for the Vapi Web or Vapi iOS SDKs. There you'll find detailed instructions and examples on how to implement the SDK in your application.
If you need direct links to the documentation or specific guidance on using the SDKs, please let me know which platform you're working with (Web or iOS), and I can provide more detailed assistance.

"monitor": {
"listenUrl": "wss://aws-us-west-2-production3-phone-call-websocket.vapi.ai/7e7e768a/transport",
"controlUrl": "https://aws-us-west-2-production3-phone-call-websocket.vapi.ai/7e7e768a/control"

09/09/2024, 7:59 AMyea, i understand that hence why i need to decode it
The error EncodingError: Failed to execute 'decodeAudioData' on 'BaseAudioContext': Unable to decode audio data suggests that the audio data being received is in a format that cannot be decoded by the Web Audio API.

Copy code
ts
ws.onmessage = function(event) {
const message = event.data;
if (typeof message !== 'string') {
//message is an ArrayBuffer, which is the raw PCM audio data
const audioBuffer = new Uint8Array(message);
console.log('Received audio data:', audioBuffer);
// You can then process or decode this audio data for playback or analysis
}
};s
