Online Audio Equalizer
Equalize any song or recording with a 10-band EQ — free, in your browser. Boost bass or treble, bring vocals forward, clean up a podcast or make a telephone effect, hear it live and download an MP3 or WAV. Nothing is uploaded.
Tip: small moves of 2–4 dB go a long way. Double-click a slider to reset it. Press Space to play or pause.
How it works
- Drop in a songAny audio or video file from your device. The EQ starts flat, so nothing changes until you move a slider.
- Shape the soundPick a preset, then drag the ten bands while it plays. The curve shows the overall change.
- DownloadMake an MP3, M4A or WAV — the limiter keeps boosted bands from clipping.
What each band does
FAQ
Is my song uploaded?
No. Everything happens inside your browser on your own device — the processing, the preview and the final file. Your audio is never sent anywhere.
How do I make vocals clearer?
Try the Vocal boost preset: it lifts 1–4 kHz where voices sit and trims the low end. For speech, Podcast voice also removes rumble.
What is the “smile” EQ?
Bass and treble boosted, mids dipped — the shape looks like a smile. It makes music sound bigger and more exciting at low volume.
Why does the output get a little quieter when I boost?
To leave room for the boosted bands, the overall level is lowered slightly before the limiter, so the file doesn’t clip. Use Output level to bring it back up.
Can I apply EQ to a video’s audio?
Yes — drop the video in and the audio is equalized and saved as MP3, M4A or WAV. The video picture isn’t included.
Can I hear the difference?
Yes. Press Compare with original while it plays to flip between the untouched song and your version at the same spot.
Can I upload the result to YouTube, TikTok or Spotify?
Only if you own the song or have permission. An edited version of someone else’s recording is still their recording, and platforms’ copyright systems will usually match it. You’re responsible for what you upload; for your own music, go for it.
Is it free?
Yes — free, no sign-up and no watermark, at full length. The site is supported by the ads on the page.
