Question 1

Why convert stereo to mono?

Accepted Answer

Mono sounds the same through one earbud, a phone speaker or a single smart speaker, which matters for voice recordings and podcasts. Some upload forms, phone systems and speech tools also ask for mono audio.

Question 2

Does mono make the file smaller?

Accepted Answer

A mono WAV or FLAC file is about half the size of the stereo one. For MP3, M4A and OGG, the size is set by the bitrate you choose, so pick a lower bitrate if you also want a smaller file.

Question 3

When should I use Left only or Right only?

Accepted Answer

When the two channels hold different things, like an interview recorded with one microphone per channel, or a recording where one side is noisy or silent. Keeping one side avoids mixing in the bad channel.

Question 4

Can mixing to mono make some sounds quieter?

Accepted Answer

Sounds that are out of phase between the left and right channels get quieter, or cancel, when the channels are averaged. It is rare in normal recordings but can happen with wide stereo effects.

Question 5

Can I convert the sound of a video to mono?

Accepted Answer

Yes. Drop the video and you get a mono audio file of its sound. The video itself is not changed or returned.

Question 6

Is my file uploaded?

Accepted Answer

No. The channels are mixed in your browser and the file never leaves your device.
