Mono vs Stereo
Updated October 2026
Mono has one channel; stereo has two, left and right. A single voice does not need two channels, so mono is usually the better choice for speech. Stereo suits music and effects that move across the sound field.
The short version
- Mono has one channel; stereo has a left and right channel.
- A single voice recorded in mono sounds the same and is half the size.
- Stereo suits music, ambience and effects that move across the sound.
- Check that a stereo recording is balanced before you convert to mono.
The short definition
Mono is one channel of sound, played from both speakers equally. Stereo has two channels, left and right, which can carry different sound.
For voice
A voice recorded in mono is the same voice, and the file is half the size of stereo. Most podcasts and voiceovers are mono. A stereo recording of one voice often has the same sound in both channels anyway.
For music
Stereo gives width and movement, which music and effects use. Keep stereo for a mix that needs it.
Converting
Check that the two channels are balanced and not out of phase before you convert. A cancelling channel can thin the sound when it is summed to mono.
