5-band EQ tuned for AI music. Cuts 200–400Hz mud, removes sub-bass, boosts presence and air. A/B preview + export clean WAV. No upload, no login.
AI music generators produce all instruments simultaneously in a single pass. Human mixing engineers spend hours carving EQ space for each element. Here's what that means in frequency terms:
Sub-bass rumble
Inaudible on most speakers but consumes headroom and causes intermodulation distortion. Found in 89% of AI tracks. The high-pass filter removes it entirely.
The mud zone
Kick drum, bass guitar, piano, and vocals all share this space. Human engineers carve EQ separation between each instrument. Suno doesn't — they all build up together creating a boxy, congested sound.
Presence gap
The mud buildup below often masks the presence range above. Boosting 3–5kHz after cutting the mud zone restores instrument definition, vocal clarity, and the sense that the mix is 'open'.
Dull top end
AI music frequently sounds dull or closed in the highs. A gentle high-shelf boost at 12kHz adds air and opens the top end without adding harshness.
Suno generates all instruments simultaneously without applying the EQ separation that human mixing engineers spend hours on. Every instrument — kick drum, bass, piano, vocals — shares the same 200–400Hz frequency space and none of them are carved out to make room for the others. This creates a buildup in the low-mid range that makes the overall sound feel congested, boxy, or like there's a blanket over the speakers. A targeted cut at 250–350Hz removes this buildup without affecting the rest of the frequency response.
It applies a 5-band parametric EQ chain designed specifically for AI music: a high-pass filter at 30Hz removes inaudible sub-bass that consumes headroom; a peaking cut at 250Hz removes the mud zone buildup; a second cut at 400Hz handles additional low-mid congestion; a presence boost at 3.5kHz restores definition and clarity; and a high-shelf at 12kHz opens the top end. All processing happens in your browser via the Web Audio API — nothing is uploaded.
Use it before mastering. The mud cut recovers headroom that the mastering limiter can then use more cleanly. The workflow is: Suno export → Suno Clarity (EQ) → MixMasterAI mastering → download. This gives the mastering engine cleaner, more balanced material to work with, and the result will be noticeably better than mastering the raw Suno output directly.
The default is -3dB which is a good starting point for most Suno tracks. Use the A/B preview to listen to the difference — if the track still sounds congested, push to -4 or -5dB. If you cut too far the track will start to sound thin and hollow. The sweet spot for most AI music is between -2 and -4dB at 250Hz. Adjust by ear rather than by number.
