EQK 3.0 FAQ
How does EQK learn my listening preferences?
EQK uses an on-device AI engine that analyzes songs as they play, adjusting the EQ in real time. It saves per-song and per-app profiles locally, so the second time you play the same song, it starts with a refined EQ curve.
Can I use EQK with streaming services like Spotify or Apple Music?
Yes, EQK works as a per-app equalizer, so you can route any audio app—including Spotify, Apple Music, Tidal, or web browsers—through it and apply custom EQ settings per app.
What happens if I exceed the 1,000 song profile limit?
EQK stores up to 1,000 song profiles. When the limit is reached, older or less-used profiles may be automatically overwritten by new ones. The Optimizer engine can help manage and clear incomplete profiles.
Does EQK require an internet connection to work?
No, EQK is fully on-device. It does not send any audio or listening data to the cloud, and all AI processing happens locally on your Mac.
Is there a free trial available?
Yes, EQK offers a 14-day free trial so you can test the full features before making a one-time purchase.
Can I manually adjust the EQ curves, or is it fully automatic?
EQK is designed to be automatic, but it provides an interface where you can fine-tune the EQ if desired. The AI learns from your adjustments and incorporates them into future profiles.
Does EQK support external DACs or audio interfaces?
EQK works with any audio output device recognized by macOS, including external DACs and audio interfaces, as long as they are compatible with the system's audio routing.
