EasyEffects vs SotF

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.

SotF is a free, open-source audio player and optimizer for room and headphone sound, available for Linux, macOS and Windows. It plays FLAC, MP3, AAC, ALAC and Vorbis files, and lists more than 40 audio plugins for equalization, compression, limiting, upmixing, binaural processing, convolution and denoising. Room EQ analyzes room response and calculates correction filters for a plugin chain; using it requires a measurement microphone, its calibration file and connected speakers. Headphone EQ calculates parametric filters targeting the Harman curve for hundreds of measured headphone models. Spinorama EQ provides correction for thousands of speakers without a microphone. SotF can export settings for CamillaDSP, Equalizer APO, EasyEffects, Wavelet, PipeWire and Roon. On macOS, a CoreAudio HAL virtual device can route audio from other apps through a configured plugin chain. The app runs on the user’s machine and says it does not collect user data or listening history. Speaker EQ queries the public Spinorama API for the selected model. SotF is GPL-3.0 licensed and has no subscription.
