Frequently Asked Questions

Why do some smartphone or mic recordings only play in one ear?

Many external microphones record on channel 1 (Left) leaving channel 2 (Right) blank. Converting to mono copies the active signal to both channels, restoring balanced listening on headphones.

Does converting stereo to mono cut file size?

Yes! Storing one acoustic channel instead of two cuts uncompressed audio bitrates exactly in half, delivering immediate file size savings.

Can I select just the Left channel or just the Right channel?

Yes. You can choose to sum both channels or isolate the Left or Right channel exclusively if one side contains background noise.
