Why use the audio equalizer tool from Super Utility Hub?
Shape the sound of any audio file with a simple three-band equalizer. Boost the bass for warmth and punch, tame harsh treble, or cut the mids to clear up a muddy mix — with live preview so you hear every change instantly.
The equalizer uses professional biquad filters (the same type found in studio EQs) at 250 Hz for bass, 1 kHz for mids and 4 kHz for treble. Each band adjusts from -12 dB to +12 dB.
Preview the effect live on your file, then export the processed audio as a lossless WAV. Everything runs locally — no uploads, no limits.
- Processes everything in your browser — no upload servers involved
- Free forever with unlimited uses
- Works on Windows, macOS, Linux, Android and iOS
- No watermark or branding on your output, ever
Frequently asked questions
What frequencies do the bands cover?
Bass is centered at 250 Hz, mids at 1 kHz and treble at 4 kHz — a classic three-band layout that covers most listening situations.
Can I preview before exporting?
Yes. The preview plays the file through the exact same filters, so what you hear is what you get in the export.
Is the export lossless?
The WAV export is lossless PCM. The filter math itself is high-precision, so you only lose what you intentionally cut.
