CamillaDSP vs Radioform

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.

Radioform is a free, open-source system-wide equalizer for macOS. It routes audio from Mac applications through a virtual output device and EQ engine to selected speakers or headphones. The equalizer provides ten bands from 32 Hz to 16 kHz, with adjustable gain and Q. Built-in presets cover Electronic, Acoustic, Classical, Hip-Hop, Pop, R&B, Rock, and Flat, and users can save named curves for particular headphones. A limiter and preamp are included to catch clipping when EQ is pushed hard. Radioform switches output devices without restarting and keeps equalization active after the change. It requires macOS 13.0 Ventura or later and runs on Apple Silicon and Intel Macs. The maker reports under 1% CPU usage on Apple Silicon and no audible delay. Releases are Apple-signed and notarized, with updates delivered through Sparkle. The maker says no data is collected. Radioform is licensed under GPLv3; its audio engine uses C++, while the native Swift and SwiftUI menu bar app uses macOS CoreAudio.
