What CamillaDSP is

CamillaDSP is a free, open-source family of tools for real-time audio processing on Linux, macOS, and Windows. It can split audio into crossover bands, apply room correction, and assemble advanced DSP pipelines. The engine chains filters and mixers, and supports channel mixing, resampling, dynamic loudness, IIR biquad filters, and FIR filters processed with FFT/IFFT convolution. Room correction can combine FIR correction filters with EQ and delay adjustment. Audio backends include ALSA, PulseAudio, JACK, WASAPI, and CoreAudio. CamillaGUI is a browser interface for building and editing pipelines, monitoring levels, and applying changes live; it runs through a local backend and does not require 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.

Who it suits

CamillaDSP suits people building audio crossovers, room correction, or custom DSP pipelines. The GUI offers local browser control, while pyCamillaDSP supports automation integrations.

What it does well
