Purpose-built for the macOS audiophile workflow. No bloat, no drivers, no kernel extensions.
Monitors Apple Music and switches your output device to the track's native rate. No audio gaps. Bit-perfect, first time and every time.
Live frequency response graph from 20 Hz to 20 kHz. Add, remove, and reorder filters. Adjust frequency, gain, and Q with precision sliders.
Biquad filter coefficients computed in 64-bit, applied sample-by-sample in 32-bit float. Maximum accuracy with zero compromise on performance.
Calculates peak filter response and sets compensating pregain with optional headroom. Ratcheted design: volume can only decrease, never silently increase.
Dual-tab mode for side-by-side comparison. Intelligent level matching ensures a fair A/B test — no loudness bias, just the EQ difference.
Multiple named profiles per headphone, organized by model in the menu bar. Switch EQ with a single click. Plain text files you own and control.
No lock-in, no proprietary formats. MusEQ speaks the same language as the most popular headphone EQ tools.
Import EQ profiles from the community's most trusted sources, or build your own from scratch.
The standard format used by AutoEQ and Squig.link. Import, edit, and share freely.
Import an oratory1990 measurement PDF and MusEQ extracts the EQ preset automatically.
Profiles live in ~/Documents/MusEQ/, organized by headphone model. Version control, sync, or share them however you like.
Import profiles from OPRA — an open community-maintained directory of headphone EQ profiles, aggregating data from AutoEQ, oratory1990, and others.
Purpose-built for bit-perfect Apple Music playback and headphone EQ — not a bolt-on to a larger product.
