About Stereo to Mono Converter

About Stereo to Mono

Stereo to Mono folds a two-channel recording down to a single channel. Mono is smaller, plays consistently on single-speaker devices, and is the standard for many spoken-word podcasts where stereo adds nothing.

The tool sums the left and right channels into one, so the result is mono-compatible everywhere.

Frequently Asked Questions

Why convert to mono?

Smaller files, consistent playback on phones and smart speakers, and no phase surprises. Spoken-word podcasts are commonly delivered in mono.

Will I lose anything?

Any true left/right separation collapses to centre. For voice that's usually fine; for music with hard-panned parts, check the fold-down first.
