## What it is
CamillaDSP is a flexible real-time audio processing engine written in Rust that applies IIR (biquad) and FIR (FFT convolution) filters and mixers to audio streams. It runs as a command-line application on Linux, macOS, and Windows, capturing from and playing to devices via ALSA, PulseAudio, PipeWire, Jack, WASAPI, ASIO, and CoreAudio.

## Use cases
- build an active crossover for 2-way or multi-way speakers
- apply room correction filters to my audio playback
- process audio with FIR convolution filters in real time
- route and mix audio channels on a Raspberry Pi music streamer
- correct speaker frequency response with REW-generated filters
- resample and filter audio between capture and playback devices

## When to choose
- you need flexible real-time IIR/FIR filtering for hi-fi or DIY speaker setups
- you want a cross-platform DSP engine controllable via websocket or a web GUI
- you run a headless Linux audio player (e.g. Raspberry Pi) and need room correction or crossovers

## When to avoid
- you need a graphical DAW-style audio editor rather than a config-driven engine
- you only need simple volume control or basic OS-level audio settings
- you want a plugin inside an existing media player rather than a standalone pipeline

## Facets
- artifact type: application
- maturity: active
- function: audio-processing, cli, websocket
- domain: cross-platform, developer-tools
- platform: windows, rust, cli
- tags: dsp, iir-filters, fir-filters, crossover, room-correction, alsa, pipewire, wasapi, coreaudio, hi-fi-audio, audio, linux, macos
