EQ Studio
Shape your track. Hear every change. Export when you're happy.
A parametric equalizer for audio that runs in your browser. Load a track, move the bands on the frequency graph, switch between the original and your EQ, and listen as it plays. Nothing is uploaded to listen. If you want the processed file, export it as a full-quality WAV for €1.99.
This browser doesn't support the audio features EQ Studio needs (Web Audio). Try a current version of Chrome, Edge, Firefox or Safari.
DROP YOUR TRACK
or click to choose a file
WAV, MP3, AIFF or FLAC. The file stays on your device while you listen and adjust. It is uploaded only if you export. Privacy notice.
Starting points
Bands
Drag a numbered point on the graph, or type exact values. Arrow keys move a selected point (hold Shift for fine steps), the mouse wheel changes Q on a bell, and a double click returns a point to 0 dB.
Export
Listening is free. A processed full-quality WAV costs €1.99 per track, paid once, with no subscription.
Your file is uploaded for this export only.
By exporting you agree to the terms; uploaded files and results are deleted automatically as described in the privacy notice.
Your EQ export
An online EQ you can actually listen through
EQ Studio is a five-band parametric EQ. The low band is a shelf, the three middle bands are bells you can narrow or widen with Q, and the high band is a shelf. You can change the type of any band, for example to a high-pass filter to remove rumble. The curve on the graph is calculated from the same band settings the audio engine uses, so what you see is what you hear. That is the difference between a real equalizer for audio and a picture of one.
- Load your track. It is decoded in your browser. Nothing is sent anywhere.
- Shape it. Drag the points on the frequency EQ graph, pick a starting point, or type exact values for each band.
- Compare. Switch between Original and EQ while the track plays. Turn on loudness matching so a louder version does not simply sound better.
- Export when you're happy. The same settings are applied to the full-quality file on our server and you download it as a 24-bit WAV.
Starting points, not magic settings
These presets each make one small, labelled move. They are meant to be a place to begin listening, and every band stays editable afterwards. None of them is a genre setting or a promise about how your track will sound.
Reduce Mud
A gentle cut around 250 Hz, where low-mid build-up often sits.
Clean Low End
High-pass at 30 Hz plus a small cut at 120 Hz to tighten the bass.
Add Air
A soft high shelf from 12 kHz upward.
Gentle Presence
A wide, small boost around 3.5 kHz.
Tame Harshness
A narrow cut around 3 kHz, where harshness often lives.
Warm Tilt
A little more low end and a little less top end.
What EQ does, and what it does not do
Parametric EQ changes how loud different frequency ranges are. Cutting a little around 250 Hz can clear a muddy mix, a gentle boost near 3.5 kHz can bring a vocal forward, and a high shelf adds or removes brightness. It is the right tool for tonal balance.
EQ does not fix a problem that is not about frequency. It does not control dynamics, make a track louder in a competitive way, widen the stereo image, repair clipping or remove a noise that sits in the same range as the music. It cannot add detail that was never recorded. Large boosts also raise the level of everything in that range, noise included, so smaller moves usually work better. For compression, limiting and loudness, that is the job of mastering.
Not sure what your track needs? Use the free Frequency Analyzer to see where its energy sits, or the Track Analyzer for a full measurement. If you want a reference point, compare it with a reference track. When the tonal balance is right and you want the complete chain, continue to Adaptive Mastering.
Questions
Is the online EQ free?
Yes. You can load a track, move the bands, compare with the original and listen as long as you like without paying or creating an account. You only pay if you want to download the processed track.
Is my track uploaded while I listen?
No. The file is decoded and played in your browser. It is uploaded only when you choose to export, because the full-quality file is rendered on our server.
Will the exported file sound like the preview?
The export uses the same filter formulas and the same band settings you see on screen, and a flat EQ is returned unchanged. The browser preview can differ very slightly at the very top of the spectrum for files with a low sample rate, and your speakers and headphones are of course part of what you hear.
Does it change the volume?
Boosting frequencies makes a track louder and cutting makes it quieter, which can make the EQ version sound better only because it is louder. The loudness-match switch estimates that change from the track's average spectrum and lowers or raises the EQ side while you listen. It is an estimate, it only affects playback, and it never changes the exported file. If your boosts would push peaks above full scale, the export lowers the whole file by one constant amount to prevent clipping and tells you how much.
What format do I get back?
A 24-bit WAV with the same sample rate and channel count as your source. If your source is an MP3, the WAV contains that decoded audio; it cannot restore detail the MP3 already discarded.
Is this mastering?
No. EQ Studio only changes the tonal balance with the bands you set. There is no compression, limiting, loudness normalisation, stereo widening or saturation. If you want a complete mastering chain, use Adaptive Mastering.
