## What it is
JamesDSP for Linux is an open-source audio effect processor providing system-wide sound effects for PipeWire and PulseAudio clients. It is a Linux port of the Android JamesDSP app, offering equalizers, bass boost, convolver, and other DSP effects through a GUI.

## Use cases
- apply system-wide equalizer on linux
- boost bass of all audio output
- add reverb to system audio
- load impulse responses for convolution
- apply autoeq headphone correction
- crossfeed for headphones on linux

## When to choose
- you want system-wide audio effects on PipeWire or PulseAudio
- you need an equalizer, bass boost, or convolver for all apps
- you want an open-source alternative to Windows audio enhancers

## When to avoid
- you need audio effects on Windows or macOS
- you only need per-app volume control without DSP effects
- you want a lightweight CLI-only tool

## Facets
- artifact type: application
