About Audio Equalizer

Audio Equalizer lets you shape an audio file's bass, mid, and treble in real time as it plays, then export the equalized result as a downloadable WAV file — using the Web Audio API entirely in your browser. Export renders the file offline through the same filter settings, so you don't need to play it back in real time to get the processed file.

How to use Audio Equalizer

  1. 1Click the upload area and select an audio file.
  2. 2Press play on the audio player to preview changes live.
  3. 3Adjust the Bass, Mid, and Treble sliders (-12dB to +12dB) while it plays.
  4. 4Click "Export as WAV" to render the equalized audio at your current slider settings and download it.

Frequently Asked Questions

Can I download the equalized audio file?

Yes — click "Export as WAV" to render the audio through your current Bass/Mid/Treble settings and get a downloadable WAV file, independent of what's currently playing.

Can I save my EQ settings as a preset?

Not currently — each adjustment only applies to the current session; there's no saved-preset feature.

What format is the exported file?

Always WAV, regardless of the format you uploaded.

What audio formats can I upload?

Any format your browser can play, such as MP3, WAV, OGG, or FLAC.

Is my file uploaded anywhere?

No. Everything happens locally in your browser via the Web Audio API — your file is never uploaded to a server.

Tips & Tricks

  • ✓Make small adjustments and listen carefully — extreme boosts near ±12dB can introduce distortion audible in the exported file too.
  • ✓Boost the bass shelf for warmth, cut the mid range to reduce muddiness, and boost treble for clarity and presence.
  • ✓The exported WAV reflects whatever the sliders are set to at the moment you click "Export as WAV" — no need to have the track playing first.
  • ✓WAV files are uncompressed and can be large — convert the download afterward with the Audio Converter if you need a smaller MP3.
