#Audio service

Provides core audio functionality: audio device access and enumeration.

Runs

  • In a separate process on Windows, Mac (sandboxed) and Linux (unsandboxed);
  • In the browser process on other platforms.

Can be accessed from trusted processes only (the browser process and certains utility processes). Use audio::CreateInputDevice() for the mic capture, and audio::OutputDevice for the playback.

Untrusted processes should use media::AudioInputDevice and media::AudioOutputDevice correspondingly, which will take care of device authorization.
