What people use it for
- Muffled voices
Adding clarity makes speech easier to follow in classes, meetings and podcasts.
- Muddy recordings
Taking out some low-mid body cleans up a recording made in a small room.
- Flat-sounding music
A touch of bass and sparkle brings life to a dull track.
- Matching your device
Compensating for very bass-heavy headphones or very bright speakers.
- Getting ready to publish
A quick fix before putting the audio in a video or on a platform.
Tips for a better result
- 01Move one control at a time.
That way you hear what each one does before moving on.
- 02Cutting usually beats boosting.
Lowering what is too much sounds cleaner than raising everything else.
- 03For voice: 250 Hz and 4 kHz.
Lower 250 Hz a little if it sounds muddy; raise 4 kHz a little if it sounds muffled.
- 04Zero means original.
With every band at 0 dB, the sound stays exactly as it was.
Common questions
Can I equalize an MP3 online?
Yes. Choose the MP3, move the five sliders while you listen and download the new version as MP3 or WAV.
Is there a sound equalizer website that works on a phone?
This one does. It runs in the browser of your phone or computer, with no app to install.
Where do I start?
For a muffled voice, raise 4 kHz a little. For a boomy recording, lower 250 Hz.
What does each slider do?
60 Hz is the deep bass, 250 Hz the body, 1 kHz the middle, 4 kHz the clarity of the voice and 12 kHz the shine.
