EQBase vs EqLume

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.

EqLume is a free system-wide equalizer for Apple silicon Macs running macOS 26.0 or later. It detects the genre of the current track and applies a matching EQ preset, with 21 presets that include hip-hop, EDM, rock, jazz, classical and ambient. The menu bar app shows a live spectrum analyzer and an EQ response curve. EqLume reads now-playing details from Spotify, YouTube Music, Apple Music and supported browsers, and offers transport controls for Spotify, Apple Music and YouTube Music. It uses a Core Audio process tap to capture system audio without a virtual audio driver or kernel extension. Audio is processed in memory, not recorded to disk or uploaded. Track and artist names may be sent to MusicBrainz and Apple iTunes Search for lookups. The built-in 3.5 mm headphone output uses tuned correction; other outputs can be enabled per device, while built-in speakers are unprocessed. The Mac App Store version omits the optional on-device classifier.
