What it is

EQBase is a system-wide macOS equalizer that processes sound from apps in real time. It includes a 10-band EQ and measured correction profiles for more than 8,600 headphone models. The free tier has no time limit and can record system audio in MP3, AAC, ALAC, FLAC, WAV, or AIFF. Pro adds microphone-based room measurement and a fitted parametric correction curve, per-app volume, mute and tone controls, and routing audio sources to one or more outputs. Pro also supports Audio Unit plugins. EQBase uses headphone correction curves from the open-source AutoEQ project. Audio is processed locally; the privacy policy says audio content, recordings, and listening information are not collected, stored, or transmitted. Normal setup does not install a driver, while optional Audiophile mode and Pro routing use a user-space Core Audio driver. It requires macOS 14.4 or later and supports Apple silicon and Intel Macs. Pro Monthly costs $4.99 per month for three Macs; Pro Annual is $39.99 per year for three Macs, and Pro Lifetime costs $79.99 once for one Mac.
