In detail

MP3 is what a voice recorder, a phone app or a podcast host gives you, and it's a perfectly good format to transcribe from. Compression throws away what the ear can't hear, and speech recognition doesn't need what the ear can't hear.

Bitrate barely matters either. From 64 kbps upwards the accuracy is essentially the same; what does move it is how close the microphone was and whether two people talk at once. A 32 kbps recording from across a room is the one case worth re-recording.

  • Any bitrate from 32 kbps up, mono or stereo, constant or variable.
  • Long files handled whole: a three-hour podcast doesn't need splitting.
  • The ID3 tags don't matter, and neither does the file name.
  • Speakers separated even when the MP3 is a mono mixdown of several mics.

What people use it for

Voice recorders

Almost every handheld recorder writes MP3 by default. Drop it in as it comes.

Podcast episodes

The published MP3 is enough: no need to go back for the session files.

Voice notes

A phone memo of an idea at two in the morning is still a transcribable file.
