EasyEffects vs Radioform

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.

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.
