Audio Processing

Choose your microphone and clean up the captured audio for clearer, more accurate transcripts.

Audio Processing (Settings → Audio Processing) lets you pick which microphone Maestra Live captures from and apply browser-level audio cleanup before your speech is transcribed.

Choose your microphone

Use Select microphone input to choose which microphone Maestra Live captures audio from. If a device isn’t listed, make sure it’s connected and that your browser has access to it.

You’ll need to grant Maestra Live permission to use your microphone the first time, if you haven’t already.

You can also switch microphones while a transcription is running. Select the mic icon in the session controls to open the picker, then search for and choose a device without stopping the session.

Processing options

Three browser-level controls help clean up the captured audio so the transcript stays accurate.

Echo cancellationReduces echo caused by speaker or system audio picked up by your microphone.
Noise suppressionReduces background noise in your audio.
Auto gain controlAutomatically adjusts microphone volume for consistent levels.

Echo cancellation modes

  • Always off: echo cancellation is never applied.
  • Default (on for dubbing, off for transcription): on for dubbing to prevent the dubbed voiceover from feeding back into the mic, off for transcription/translation so you can capture sound playing through your computer’s speakers.
  • Always on: echo cancellation is always applied.
