CamillaDSP vs EqLume

CamillaDSP is a free, open-source family of tools for real-time audio processing, including active crossovers, room correction, and configurable DSP pipelines. Its engine runs on Linux, macOS, and Windows, with audio backends including ALSA, PulseAudio, JACK, WASAPI, and CoreAudio. Pipelines combine filters and mixers, with channel mixing, resampling, dynamic loudness, and chains of filter stages. Filtering includes IIR biquads and FIR filters processed through FFT/IFFT convolution; room correction can use FIR filters alongside EQ and delay adjustments. CamillaGUI is a browser interface for building and editing pipelines, monitoring levels, and applying changes live. It runs from a local backend and does not need an internet connection. For automation, pyCamillaDSP connects to a running engine over its WebSocket API, which must be enabled with the -p flag. The software is available under GPL version 3 or Mozilla Public License 2.0; an ASIO backend build is GPLv3 only. Major releases may require configuration updates, while minor releases preserve compatibility.

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.
