## What it is
FunDSP is a Rust library for audio processing and digital signal synthesis with a composable inline graph notation for building audio networks. It includes a suite of audio components, analytic frequency response analysis, and supports no_std environments.

## Use cases
- generate sound effects procedurally for games
- build a software synthesizer in Rust
- prototype DSP filter algorithms
- analyze frequency response of audio networks
- learn audio DSP concepts
- embed audio synthesis in no_std firmware

## When to choose
- you need composable, zero-cost audio graph abstractions in Rust
- you want procedural audio for games or embedded systems
- you need analytic frequency response analysis of linear filters

## When to avoid
- you need a full DAW or sample-based music production suite
- you want a high-level audio engine with built-in playback devices and mixing
- you need non-Rust language bindings

## Facets
- artifact type: library
- maturity: active
- function: audio-processing, simulation, math
- domain: media, embedded-systems
- platform: rust, cross-platform, embedded
- tags: dsp, synthesis, no-std, audio-graph, frequency-response, procedural-audio, audio, game-development
