CamillaDSP vs EasyEffects

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.

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.
