EqLume vs Radioform

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.

Radioform is a free, open-source system-wide equalizer for macOS. It routes audio from Mac applications through a virtual output device and EQ engine to selected speakers or headphones. The equalizer provides ten bands from 32 Hz to 16 kHz, with adjustable gain and Q. Built-in presets cover Electronic, Acoustic, Classical, Hip-Hop, Pop, R&B, Rock, and Flat, and users can save named curves for particular headphones. A limiter and preamp are included to catch clipping when EQ is pushed hard. Radioform switches output devices without restarting and keeps equalization active after the change. It requires macOS 13.0 Ventura or later and runs on Apple Silicon and Intel Macs. The maker reports under 1% CPU usage on Apple Silicon and no audible delay. Releases are Apple-signed and notarized, with updates delivered through Sparkle. The maker says no data is collected. Radioform is licensed under GPLv3; its audio engine uses C++, while the native Swift and SwiftUI menu bar app uses macOS CoreAudio.
