Two-way audio: talk through the camera

Someone at the door, a pet on the sofa, a parent in the next room: hold Talk on the computer and the camera phone says it out loud. The phone shows who is talking while it plays.

  • 48kHzOpus, mono
  • 20msAudio packets
  • 2sOf silence ends a talk
  • Android 10Or newer, on the camera phone

How to talk

On the desktop app’s Camera page, or on a camera in full screen or a pop-out on the wall:

  1. Choose the microphone to talk with and check its level.
  2. Hold to talk, or click once to keep talking until you click again.
  3. Let go. The talk ends on release, after 2 seconds without audio, or when the phone disconnects.

On the phone

  • It plays your voice from its loudspeaker at the Talkback volume set in Settings → Audio, which you can also change from the computer.
  • It shows “studio-pc is talking” (your computer’s name) on the camera screen and in its notification, or “Someone is talking”.
  • It turns on echo cancellation while it plays, so your own voice doesn’t come back through its microphone.

One person talks at a time. Talk audio is Opus, mono, 48 kHz, in 20 ms packets, sent over your network only.

Requirements

  • The camera phone needs Android 10 or newer and Camlane 0.2 or newer. Older phones and versions say so on the computer instead of failing silently.
  • Talking comes from the desktop app (and camlane-cli listen with talk N). Talking from another phone arrives with Watch on Android, which is in progress.

Talking isn’t recording: talk audio isn’t stored, and the recorder never records sound.
