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.
