In their own words
JamesDSP
JamesDSP is a free, open-source audio effects processor for Linux clients using PipeWire or PulseAudio. Its tools include automatic bass boost, multiband dynamic range compression, reverb, equalizers, crossfeed, soundstage widening, analog modeling, and an output limiter. A partitioned convolver supports mono, stereo, and full or true stereo impulse responses. The arbitrary response equalizer uses the AutoEQ database and requires a network connection. Users can build live DSP effects with EEL2 scripting in a minimal IDE that provides syntax highlighting, basic code completion, and console output. PipeWire is the intended backend; PulseAudio remains supported in maintenance mode. Selective app exclusion and changing the target device are available only for PipeWire clients. Since version 2.5.0, D-Bus IPC and command-line controls can manage settings, presets, devices, and preset rules. Installation options include Flatpak, Arch AUR, Fedora and openSUSE packages, or a source build. The Flatpak is sandboxed and has access only to its application data directory by default. The project is GPLv3 licensed and provides no warranty.
SotF
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.
