EqLume vs JamesDSP

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.

JamesDSP is a free, open-source audio effects processor for Linux clients using PipeWire or PulseAudio. Its tools include automatic bass boost, multiband dynamic range compression, reverb, equalizers, crossfeed, soundstage widening, analog modeling, and an output limiter. A partitioned convolver supports mono, stereo, and full or true stereo impulse responses. The arbitrary response equalizer uses the AutoEQ database and requires a network connection. Users can build live DSP effects with EEL2 scripting in a minimal IDE that provides syntax highlighting, basic code completion, and console output. PipeWire is the intended backend; PulseAudio remains supported in maintenance mode. Selective app exclusion and changing the target device are available only for PipeWire clients. Since version 2.5.0, D-Bus IPC and command-line controls can manage settings, presets, devices, and preset rules. Installation options include Flatpak, Arch AUR, Fedora and openSUSE packages, or a source build. The Flatpak is sandboxed and has access only to its application data directory by default. The project is GPLv3 licensed and provides no warranty.
