In their own words
CamillaDSP
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.
FxSound
FxSound is a free Windows audio-processing application founded in 1999. It adjusts timbre, volume, spatial balance, and dynamics, with an equalizer, effects, and presets for shaping sound. The maker lists music, gaming, transcription, video, calls, and general listening as uses, and mentions Zoom calls. Audio routing and volume controls let users tailor output for their hardware. Windows downloads are offered for Intel/AMD x86/x64 and ARM64 systems. FxSound includes noise reduction, virtual surround, and equalizer controls, but no app-specific profiles. The maker says the project became free in 2022 and open-source in 2023. Its website does not use cookies or sell or rent personal information.
