How to equalize audio online
- Drop a track into the upload box — it loads with a preview player wired straight into the EQ.
- Start from a preset — Bass Boost, Vocal Clarity, Rock, Electronic, Lo-fi or Podcast — or move the ten faders yourself (±12 dB each).
- Press play to hear your curve live and watch the spectrum analyzer respond.
- Press Apply effect to render, then download the result as MP3 or WAV.
This audio equalizer online behaves like the graphic EQ on a hardware rack: ten fixed bands from deep sub-bass at 31 Hz to airy treble at 16 kHz, each on its own vertical fader. The live preview is the key feature — playback runs through the actual filter chain, so you sculpt by ear instead of guessing, with a real-time spectrum to confirm what your ears tell you. As with every SoundForge tool, processing is local: nothing is uploaded and nothing is watermarked.
Use it to tame boomy podcast recordings, carve space for vocals, brighten dull old rips, build a lo-fi character or prepare gym-ready bass-heavy versions. If you only need more low end, the dedicated Bass Boost tool is quicker; for overall loudness, see the Volume Booster.
FAQ
How many bands does this audio equalizer have?
Ten, at the standard graphic-EQ frequencies: 31, 62, 125, 250, 500 Hz and 1, 2, 4, 8, 16 kHz. Each fader moves its band by up to plus or minus 12 dB, with shelving filters on the lowest and highest bands and peaking filters in between.
Can I hear the EQ changes before downloading?
Yes — the preview player routes playback through the same filter chain you are editing, so moving a fader changes the sound immediately while a live spectrum analyzer shows the result. When it sounds right, press Apply effect to render the final file.
Will boosting EQ bands cause clipping?
The tool checks the rendered audio and, if your boosts pushed the peak past full scale, scales the whole file down just enough to stay clean. You keep the tonal balance you dialed in without digital distortion in the export.
Is this equalizer free, and is my music uploaded anywhere?
It is free with no account, no watermark and no limits. The filters run in your browser through the Web Audio API — your file never leaves your device — and the equalized track downloads as a 320 kbps MP3 or WAV.
