Is there a way for buffering the audio from realtime model. We are having an issue where the audio is getting chopped because of model dispatching audio in a slower rate and we would like to buffer it either on the agent or on the client

Thanks for reaching out, Praveen. I'm an AI assistant and I'm here to help. Give me a moment while I research this topic.
Hey there! If you're noticing audio chopping because the dispatch rates are a bit slow, a great way to smooth things out is by adding some buffering, either on the agent or client side. Here are a few ideas you can try: • Built-in Audio Buffering: You can use the InputAudioBuffer class to gather audio before sending it off to the model. Just make sure you have at least 100ms of audio buffered before you send it. • AudioSource Queue Configuration: Try increasing the internal buffer size by adjusting the
queue_size_ms
parameter (like setting it to 2000ms) when you create your AudioSource. This gives you more breathing room and helps avoid frame capture hiccups. • Custom Buffering: Another approach is to build your own buffer to hold audio frames. For example, you could add frames to a list and manage its size so you keep the most recent ones ready for processing. • System Buffering: LiveKit’s audio publishing system already has a 50ms internal buffer that queues audio, which can help even out those dispatch rates. • VAD-Based Buffering: You might also consider Voice Activity Detection (VAD) systems that come with configurable buffering options, like setting the max buffered speech duration and prefix padding. Would you like me to walk you through how to set up any of these? Just let me know!

We are using googles Live Api, can you give us an example

I don't have the answer you're looking for. You could also try asking your question: • in one of the other Slack channels or • to https://deepwiki.com/livekit/livekit_composite which is trained on all LiveKit source code If you find the answer, please post it here to help others!
