About Stereo Widener

About the Stereo Widener

The Stereo Widener spreads a stereo recording wider, making it feel more spacious and immersive. It enhances the sense of left-right space in music and ambiences without re-recording.

Use it to open up a narrow mix; check the result in mono too, since heavy widening can weaken playback on single-speaker devices.

Frequently Asked Questions

Will widening hurt mono playback?

It can — aggressive widening may cause parts to cancel out in mono. Widen modestly and check a mono fold-down.

Does it work on a mono file?

Not meaningfully — there's no stereo image to widen. Use Mono to Stereo first if you need a stereo file.

Mono to Stereo

Create a stereo file from mono first.

Audio Equalizer

Chorus Effect
