Thanks for reaching out, Sahil. I'm an AI assistant and I'm here to help. Give me a moment while I research this topic.
Thanks — this is a great idea and yes, you can do this. You can play background music while a long-running tool runs, stop the music when the tool finishes, and then have the system speak the tool’s response aloud. The typical flow is: 1. Start playback of your music file using the background audio player and keep the returned play handle. 2. Execute the long-running tool (optionally mark the tool as non-interruptible if you want it to always run to completion). 3. When the tool returns, call 
.stop()
on the play handle to stop the music. 4. Generate/send the spoken reply so the tool’s response is announced via TTS. A few practical notes and questions so I can give concrete code or steps: • Which environment or SDK are you using (browser JavaScript, Node, or server-side SDK)? • Where is your audio file located (local file, remote URL, or asset in your app)? • Do you want the music to loop until the tool completes, or play once? • Do you need the tool to be protected from interruptions while it runs? If you share the SDK/language and these details, I’ll give a short example showing the exact sequence (start playback, run tool, stop playback, speak result) you can drop into your code.

what is the maximum valume we can set for ambient sound
t
Thanks — I’m responding to your question about the maximum volume for ambient sound. The maximum volume you can set is 1.0 (100%). Volume is specified as a float between 0.0 (silent) and 1.0 (full volume). Values above 1.0 are not supported and may cause clipping or distortion, so they’re not recommended. If you tell me which SDK or language you’re using (browser JS, Node, or another SDK) I can show the exact code snippet to set the ambient/music volume.

ok so can i play an audio file using session.say ?
t
You're asking whether you can play an audio file with 
session.say
— yes, you can. Key points: • 
session.say()
accepts an 
audio
argument that can play pre-synthesized audio frames (an `AsyncIterable`/generator of 
rtc.AudioFrame
) instead of using TTS. • If you pass both 
text
and 
audio
, the 
text
is added to transcripts/chat while the provided 
audio
is played (the audio is not re-synthesized). • Common uses: hold music, pre-recorded messages, cached TTS, or sound effects. Minimal example pattern (Python-style pseudocode):
Copy code
async def audio_generator():
    # read and convert your WAV/MP3 into rtc.AudioFrame chunks
    yield audio_frame_1
    yield audio_frame_2
    ...

await session.say("Playing a clip", audio=audio_generator())
Practical questions so I can give a concrete snippet for your setup: • Which SDK/language are you using (browser JS, Node, Python, etc.)? • What audio format/file source do you have (WAV, MP3, remote URL, local file)? • Do you want the file to loop, stop on command, or play once? Tell me those details and I’ll provide a ready-to-use code example for your environment.

can this audio file be just a music will it still play using session.say
t
Yes — the audio you pass to 
session.say()
can be any audio (including music), not just speech. Quick summary: • 
session.say()
accepts an 
audio
argument that must be an async iterable/generator of 
rtc.AudioFrame
(pre-synthesized audio frames). Any pre-encoded audio you convert into those frames—music, sound effects, or recorded prompts—will play as-is. • If you also pass 
text
, that text goes into the transcript/chat while the provided audio file is played (the audio will not be re-synthesized to TTS). • You can control playback externally (e.g., stop or loop) by how you produce the frames or by using a background audio player and its play handle if you need stop/loop control. A few quick questions so I can give a concrete code example: • Which SDK/language are you using (browser JS, Node, Python, etc.)? • What audio format and source do you have (WAV, MP3, local file, remote URL)? • Should the music loop until you stop it, or play once? • Do you want the music played via 
session.say()
only, or would you prefer using the 
BackgroundAudioPlayer
(which provides an explicit play handle you can stop)? Tell me those details and I’ll provide a short, ready-to-use snippet for your environment. , with interactive elements
