How to reduce noise while recording?

Some phones have two microphones. A primary microphone is aimed to your mouth to record your voice, whilst also picking up any noise from around you. In a single microphone circuit, this comprises all the data that is sent via the air waves to the receiving handset.

With a secondary microphone located elsewhere, usually near the top and on the back of the handset (so it doesn’t pick up so much speech), a lot of background noise can be removed.

You can try these steps, that may or may not reduce noise:

  1. Go to in-app Settings
  2. Select Recording
  3. Select Mic selection
  4. Choose Rear microphone or Raw audio

This allows for a different mic to be used for recording. Note that this does not work on all phones. The quality of recordings depend largely on the mic hardware itself.
