Audio testing

ringo-flow runs baresip with virtual audio, so it can both play audio into a call and check what the other side receives — headless, no devices, CI-safe.

Send audio

agent.send_audio(source) switches the agent’s active-call audio source:

#![allow(unused)]
fn main() {
a.send_audio(tone(440));          // a 440 Hz sine tone
a.send_audio(file("prompt.wav")); // a WAV file
a.send_audio(silent());           // stop sending
}

tone, file and silent build an AudioSpec.

Verify what’s received

agent.verify_audio(freq, within) asserts the agent is receiving a tone at freq Hz within the time window (detected with a Goertzel filter):

#![allow(unused)]
fn main() {
a.send_audio(tone(440));
b.verify_audio(440, "5s"); // B hears A's tone within 5s
}

For a quick two-way check, verify_audio_connection(a, b) sends a tone each way and asserts both arrive:

#![allow(unused)]
fn main() {
verify_audio_connection(a, b);
}

Debugging

Run with --save-audio to write each agent’s sent/received WAVs to the working directory, so you can listen to what actually flowed.

See the Agents → Methods reference for the exact signatures.
