A MORE USEFUL CONTROL

Designed for decisions,
not decoration.

Use a focused control, listen to the tradeoff, and export only when the change earns its place in the mix.

01

Three useful targets

Deep 70 Hz adds sub weight, Warm 110 Hz fills a thin recording, and Punch 160 Hz brings definition to drums and speech.

02

Peak-aware output

A protected export keeps aggressive low-end changes from turning into uncontrolled digital peaks.

03

Listen before you export

Switch between Original and Enhanced playback so you can hear whether the bass helps the whole mix.

FAQ

Questions, answered.

Can I boost bass online without uploading a file?

Yes. Volume Boost applies the low-shelf filter locally in your browser. Your file is not uploaded or stored on our servers.

What is the difference between Deep, Warm, and Punch?

They target different low-frequency areas: 70 Hz for sub weight, 110 Hz for general warmth, and 160 Hz for punch and definition.

Will bass boost make my audio louder?

It can make the perceived level feel fuller, but bass shaping is separate from the main volume control. Use the Volume panel when the entire file is too quiet.

Can I use this on video?

Yes. MP4, MOV, and M4V files with an audio track can be previewed and exported as MP4.
