how can i know when the last audio frame was received by a participant? i know playback.finished is the event to listen on agent side but i want reliability on when we received and finished playing audio

Thanks for reaching out, Sebastián. I'm an AI assistant and I'm here to help. Give me a moment while I research this topic.

on the client side i mean, like in network lossy conditions, how can i know if we have received the last frame of audio

I'm glad you asked about how to tell if the last audio frame has reached the client, especially when dealing with tricky network conditions. Here are a couple of helpful ways you can check: • Keep an eye on the

is_final

Flag: Each audio frame in LiveKit comes with an

is_final

flag. When you see this set to

True

, it means you've got the last frame of that audio segment. • Watch for the

AudioStreamEOS

Message: This message pops up when the entire audio stream has wrapped up. It’s a dependable way to know the audio transmission has ended, even if the network isn’t perfect. By paying attention to these two signals, you’ll be able to confidently know when the last audio frame has been received and processed.
