Hi, is there a way we can fetch complete audio of each turn?

Thanks for reaching out, Abhinav. I'm an AI assistant and I'm here to help. Give me a moment while I research this topic.
To help you fetch the complete audio of each turn in LiveKit, you can reconstruct it from individual audio frames. Let me walk you through how you can do this: • Use the
collect()
Method:
The
ChunkedStream
class has a handy
collect()
method that gathers all audio frames and combines them into a single audio frame. This is probably the easiest way to get the complete audio output. • Reconstruct Audio from Events: If you’re working with integrations like AWS Bedrock, you can link incoming audio chunks to the active message by using the
audio_content_id
from the
audioOutput
event. Then, collect all frames associated with the same
response_id
and merge them with
rtc.combine_audio_frames()
. • Combine Frames: The
rtc.combine_audio_frames()
function is your friend here—it lets you merge a list of audio frames into one complete audio segment. This is also great for debugging or creating a full audio file. • Frame Collection System: You might find it useful to set up a system that listens to audio frame events during a turn, collects all frames, and then merges them into a complete audio segment. I hope this helps you reconstruct the complete audio for each turn smoothly. If you’d like me to clarify anything or need more guidance, just let me know—I’m here to help!

but this is for realtime, i use pipeline

I understand you're looking to fetch complete audio for each turn using the pipeline. Currently, LiveKit doesn’t offer this as a built-in feature since it processes audio in chunks mainly for transcription and doesn’t aggregate or expose raw audio data per turn. To get this functionality, you’d need to create a custom solution—something like buffering the raw audio frames during each turn and then exporting them once the turn is finished. This means capturing those audio frames as they come in and combining them into a full audio segment. If you'd like, I’m here to help guide you through building this custom approach or assist with any other media recording features you have in mind. Just let me know!
