Audio equalizer in your browser
A six-band EQ you play with: drag the curve, hear the change live, A/B against the original, then save as WAV or a smaller format. The file stays on your computer.

An equalizer changes the balance of low, middle and high frequencies. A muffled voice memo wants more treble; a harsh phone recording wants less; music played on small speakers gains body from a little extra low end. This one is a real six-band EQ — a low shelf, four bells and a high shelf, each with frequency, gain and Q — drawn as a curve you drag while the file plays, so you hear every move as you make it. Flip to the original at any moment to check you are actually improving things. Our starting curve adds a touch of low end and sparkle; each band moves up to ±18 dB, and a limiter after the EQ means even a heavy boost cannot clip. Processing happens on your own machine: the audio is never sent anywhere.
Questions
What are the six bands?
A low shelf, four bell filters and a high shelf — the classic mastering layout. Each band has its own frequency, gain up to ±18 dB and width (Q), so you can lift all the low end or cut one narrow ringing tone.
Do I hear the changes before saving?
Yes. The file plays through the exact same processing that the export runs, so what you hear while dragging is precisely what lands in the saved file. The Original switch lets you A/B at any time.
Will a big boost distort the sound?
No. The chain ends in a limiter that holds peaks just under 0 dB, so a strong boost gets loud but never clips into crackle.
Does equalizing a lossy file lose quality?
The file is decoded once, adjusted, and saved again. Save as WAV or FLAC and nothing is lost beyond the change you asked for; save as MP3 and one extra lossy encode happens, which is fine for casual listening.
Is anything uploaded?
No. Decoding, the equalizer and the encoder all run inside the browser. The audio never touches a server.
