What CamillaDSP is
CamillaDSP is a free, open-source family of tools for real-time audio processing on Linux, macOS, and Windows. It can divide audio into crossover bands, apply room correction, and build DSP pipelines with channel mixing, resampling, dynamic loudness, filters, and mixers. Filter options include IIR biquads and FIR processing through FFT/IFFT convolution; room correction can combine FIR correction with EQ and delay adjustments. The engine supports ALSA, PulseAudio, JACK, WASAPI, and CoreAudio audio backends. CamillaGUI provides a browser interface for building and editing pipelines, monitoring levels, and applying changes live. It is served from a local backend and does not need an internet connection. For automation, pyCamillaDSP communicates with a running engine through its WebSocket API, which must be enabled with the -p flag. The software is licensed under GPL version 3 or Mozilla Public License 2.0; builds with an ASIO backend are GPLv3 only. Major releases may require configuration updates, while minor releases preserve compatibility with existing configurations.
Good
- Runs on Linux, macOS, and Windows.
- Supports multiple audio backends.
- GUI works locally without internet access.
- Supports room correction with FIR, EQ, and delay.
- Free under GPLv3 or MPL 2.0.
Watch out
- WebSocket must be enabled for pyCamillaDSP.
- Major releases may require configuration updates.
- ASIO backend builds are GPLv3 only.
Who it suits
CamillaDSP suits users building active crossovers, room correction, or custom real-time audio pipelines. Its local GUI and Python library also serve users who want browser-based control or automation integrations.
Verdict
CamillaDSP offers flexible processing workflows, local browser control, and automation integration across three desktop operating systems. Users should account for the WebSocket requirement for Python integrations and possible configuration changes at major releases.
