## What it is
dasp is a modular suite of Rust crates providing fundamentals for digital audio signal processing (PCM DSP), including sample/frame types, conversions, ring buffers, envelope detection, and interpolation. It is allocation-free and dependency-free, designed to be a fast, portable 'std for audio DSP'.

## Use cases
- process PCM audio samples in Rust
- convert between audio sample bit depths and formats
- detect signal envelopes with peak and RMS
- resample or interpolate audio signals
- build audio synthesis or effects engines
- work with audio frames and slices without allocations

## When to choose
- you need low-level, high-performance audio DSP primitives in Rust
- you want zero dependencies and no dynamic allocations
- you want to pick only the DSP components you need via modular crates

## When to avoid
- you need a full DAW or high-level audio application framework
- you need built-in audio playback or device I/O
- you want ready-made effects plugins rather than DSP fundamentals

## Facets
- artifact type: library
- maturity: stable
- function: audio-processing, math, developer-tools
- domain: media
- platform: rust, cross-platform, embedded
- tags: dsp, pcm, audio, no-std-friendly, signal-processing, modular-crates, algorithms
