EasyEffects vs Equaliser

EasyEffects is free, open-source Linux software for applying audio effects to applications managed by the PipeWire audio server. It can process application output and microphone audio sent to recording applications. Available effects include equalizer, compressor, convolver, limiter, noise reduction, reverberation, pitch shift and stereo tools, with control over their processing order. Users can process input or output streams and exclude selected applications. Processed audio can be exposed through Easy Effects Source for recording and communication applications. Configurations can be saved, imported, reused on another system and set to load automatically for selected devices. A PipeWire tab reports version, quantum values, sample rate, installed modules and loaded clients. Most current Linux distributions package the application, and a sandboxed Flatpak includes available plugins. Some distribution packages may omit plugins needed for certain effects. EasyEffects is licensed under GNU GPL version 3 or later, and PipeWire must be installed.

Equaliser is a system-wide audio equalizer for macOS that processes audio from every app automatically. It offers up to 64 parametric EQ bands, each with separate controls for frequency, gain, bandwidth or Q, and filter type. Compare Mode lets users hear adjusted settings against the original sound in real time, and 11 factory presets cover music, movies, and other uses. Listed specifications include a 1 Hz–22 kHz frequency range, sample rates up to 768 kHz, and 32-bit float processing. Equaliser can import filter settings from Room EQ Wizard; the project also supports EasyEffects import and exporting presets for sharing with Linux users. Processing happens locally, and the app says it does not record, store, or transmit audio or include analytics or telemetry. It is free and open source under GPL-3.0. The app requires macOS 15 (Sequoia) or later and an Apple Silicon Mac. It is not notarized by Apple, so macOS may require selecting Open Anyway in Privacy & Security settings.
