How does this tool work?
Adjust three essential frequency areas to quickly correct audio that sounds muddy, harsh or thin.
Audio is decoded locally and passed through a chain of three filters centered on bass, midrange and treble. Each control applies between -12 and +12 dB of gain around its frequency area. The browser then renders a new audio signal that you can preview before exporting it as WAV. The source file stays on your device and is not uploaded to a server for processing.
How to use this tool
Import audio
Choose a supported file.
Set the three bands
Adjust bass, midrange and treble between -12 and +12 dB.
Preview and export
Listen to the result and download WAV.
Use cases
Balance a music track
Cut an overly dominant frequency area or boost a weak band to rebalance a music track quickly.
Prepare an audio clip
Compare different bass, midrange and treble balances before exporting a locally processed WAV version.
Tips and best practices
- Start with small 2–4 dB changes.
- Too much boost can cause clipping.
- Set a band back to 0 dB to leave it neutral.
