About EQK
EQK provides separate ten-band EQ, output level, device routing, and headphone correction for supported apps such as Apple Music, Spotify, TIDAL, and VLC. It includes 3,985 AutoEq-based correction profiles for headphones, earbuds, and in-ear headphones, with measurement correction and custom EQ kept independent; it can play local FLAC, ALAC, WAV, and MP3 files directly with the same EQ and correction, without system audio recording permission. EQK does not upload audio, song names, app names, or files, and optional product analytics can be disabled in Settings. The direct-download version requires macOS 14.6 or later; it is fully usable for 14 days after download, then requires a lifetime license. One license works on up to 2 Macs, with no subscription.
