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.
Five practical bands
Shape sub, body, midrange, presence, and air with 60 Hz, 230 Hz, 910 Hz, 3 kHz, and 14 kHz controls.
Profiles with a starting point
Use Flat, Bass lift, Vocal, Bright, or Rock, then make the final adjustment by ear.
Non-destructive by default
Your original file is never overwritten. Export creates a fresh M4A audio or MP4 video copy.
IPHONE USERS
Need this workflow often?
The iPhone app is faster for repeat edits, keeps your media workflow together, and is designed around the mobile import and export experience.
FAQ
Questions, answered.
What does the online equalizer change?
It applies five peaking filters to the file: sub, body, midrange, presence, and air. You can use a preset or adjust every band yourself.
Is the equalizer free and private?
Yes. The tool is free, and processing happens locally in your browser without an account or file upload.
Can I equalize a video file?
Yes. Import an MP4, MOV, or M4V file with an audio track and export a new MP4 after tuning it.
Should I use a preset or custom settings?
Presets are useful starting points. For the best result, compare the Original and Enhanced modes and make small changes while listening to the loudest section.
