Understanding The Bands

Sub-Bass (32Hz - 64Hz): Adds deep, thumping power to kick drums and electronic basslines.
Mids (250Hz - 2kHz): This is where the human voice and main instruments live. Boost for vocal clarity.
Treble (4kHz - 16kHz): Controls the "crispness" and "air" of the track. Boost slightly for a brighter, cleaner sound.

Frequently Asked Questions

Why does the export save as a WAV file instead of MP3?

WAV is an uncompressed, universal audio format. When you apply EQ settings and re-render the file, saving it as a WAV ensures that your boosted bass or crystal-clear treble retains its pure original quality without suffering from MP3 double-compression issues.

Is my audio uploaded to a server?

No. This tool utilizes the Web Audio API's BiquadFilterNode technology. The entire equalization process, including playback and final WAV exporting, happens 100% locally inside your browser's memory. It is extremely fast and completely private.
