What Do You Want to Change About Your Sound?
Choose the listening problem first. These curves are starting points, not automatic fixes.
Make speech easier to follow
- Problem
- A voice can be loud enough and still sound boomy, boxy or buried.
- Starting point
- Start by easing back 125–500 Hz, then add a small lift around 1–4 kHz.
- Listen for
- Listen for clearer words without thinness, hiss or sharp consonants.

Add low-end weight without losing the mix
- Problem
- A thin song or rehearsal recording may need weight rather than more overall volume.
- Starting point
- Try a gentle lift from 31–125 Hz and leave the middle bands near flat.
- Listen for
- Stop when the kick and bass feel fuller but vocals remain easy to hear.
31 Hz1255002k16k Hz
Soften an edgy top end
- Problem
- Bright cymbals, hiss or sharp vocal consonants can make a comfortable level tiring.
- Starting point
- Make a small cut around 4–8 kHz before reducing the whole treble range.
- Listen for
- Keep the detail and air you like; remove only the range that distracts you.

Give a clean recording more warmth
- Problem
- A technically clear take can still feel cold or too forward in the upper mids.
- Starting point
- Add a restrained lift around 125–500 Hz and soften 4 kHz slightly.
- Listen for
- Aim for body and ease without turning the recording muddy or dull.

How to Equalize Audio Online
Use a familiar passage and make small changes you can compare.
Open your recording
Choose an MP3, WAV or another supported file. Your original remains unchanged.
Shape and compare
Try a preset, adjust the ten bands and switch between Equalized and Original while listening.
Protect and export
Keep Auto headroom on, choose WAV, MP3, M4A, FLAC or OGG, then export your new file.
Know Which Part of the Sound You Are Changing
Ten controls provide detail; three listening regions make them easier to understand.
Midrange
Warmth, boxiness and much of speech intelligibility. Small moves here can change a voice quickly.
Treble
Presence, brightness, hiss and air. Lift for detail or cut when a recording feels sharp.
Boost Frequencies Without Ignoring Clipping
EQ boosts can push peaks above the available level. Auto headroom estimates the combined EQ response and reserves space before playback and export.
- Headroom responds to the combined curve, not the largest slider alone.
- Export checks the rendered sample peaks and applies final protection when needed.
- This protects peaks; it is not loudness normalization or a loudness target.

Equalize Audio Without Giving Up Control of Your File
The workflow stays simple from import to download.
Processed in your browser
Your selected audio is decoded and equalized on this device rather than uploaded for server-side processing.
Export in five formats
Create WAV, MP3, M4A, FLAC or OGG output at 44.1 kHz stereo for the next step in your workflow.
Original stays unchanged
Editing creates a new download. The source file on your device is never overwritten.
Use the Right Audio Tool for the Job
Equalization changes tone. Choose a focused tool when the problem is level, noise, separation or arrangement.
Audio Equalizer FAQs
Answers about 10-band EQ, MP3 files, voice settings, headroom, formats and private browser processing.
Is this online audio equalizer free?
Yes. You can adjust, preview and export one audio file for free without an account. Files are processed locally in your browser. Choose a supported file up to 100 MB and 10 minutes long; larger files within those limits work best on desktop.
Can I use this as an MP3 equalizer online?
Yes. Open an MP3, adjust its bass, mids and treble, then export the equalized audio as MP3, WAV, M4A, FLAC or OGG. The download includes your EQ changes and your source file stays unchanged.
What are good equalizer settings for voice and podcasts?
Start with Vocal Clarity or Podcast, then listen to a familiar passage. If the voice sounds boomy, try a small low-frequency cut. If it sounds dull, a gentle presence boost may help. Compare with Original because every voice, microphone and room is different.
Can I boost bass without making the song sound muddy?
Try Bass Boost, then reduce the amount if the kick or bass starts covering vocals and other instruments. A small adjustment is often enough. Auto headroom reserves space for boosted bands, but EQ cannot create deep bass that was never captured.
Does it work with YouTube, Spotify or all sound on my computer?
No. This tool equalizes audio files you choose from your device. It does not change other browser tabs, streaming services, live microphone input or system-wide speaker settings.
Can I equalize audio from a video?
You can open an MP4 with a readable audio track and export the equalized sound as an audio file. It does not export the picture. Use the Video Audio Editor when the adjusted sound needs to stay attached to a video.

Which audio formats are supported?
Import MP3, WAV, M4A, AAC, FLAC, OGG, Opus, AIFF, WMA, AMR or MP4 with readable audio. Export WAV, MP3, M4A, FLAC or OGG at 44.1 kHz stereo. Codec support can vary by browser.
Will an equalizer remove noise, isolate vocals or change pitch?
No. EQ changes the tonal balance of everything in the file. It is not AI noise removal, vocal separation, pitch correction or audio restoration, and it does not change song key or tempo.
Why does my audio get quieter with Auto headroom?
Boosted bands need room to avoid excessive peaks, so Auto headroom can lower the overall signal. Export also checks sample peaks and lowers the result if needed. This is not LUFS normalization or a true-peak guarantee.
Can I compare the original and reset my EQ settings?
Yes. Switch between Equalized and Original during playback without losing your adjustments. Flat returns the ten frequency bands to zero, while Reset also restores output gain and Auto headroom.
