desphere (Rust)
Clean-room, dependency-free NIST SPHERE (and Shorten) → RIFF/WAV transcoder —
the Rust port of the Python reference in ../src/desphere.
The Python is the spec; this reproduces its output bit-for-bit, validated
against the same committed fixtures.
let sph = std::fs::read("utt.sph")?;
let wav = desphere::transcode(&sph)?; // RIFF/WAV bytes
std::fs::write("utt.wav", wav)?;
Supports PCM (16/32-bit, both byte orders), G.711 μ-law/a-law, and
embedded-shorten v2 — including QLPC (LPC) blocks and lossless μ-law type-8
with the non-linear bitshift remap. Unsupported/corrupt input fails loud
(DecodeError), never panics — safe for WASM.
Build targets
cargo test # core, byte-exact vs fixtures
wasm-pack build --target web --features wasm # WASM (rust/pkg/)
maturin develop -m pyproject.toml --features python # Python module: desphere_native
The core library is dependency-free; the wasm (wasm-bindgen) and python
(pyo3) bindings are opt-in Cargo features that don't burden a plain Rust
dependant.
Clean-room
Built only from public sources (NIST SPHERE docs, ITU-T G.711, Robinson 1994
TR.156) and black-box oracle testing — no GPL/LGPL source was ever read. See
../PROVENANCE.md. MIT-licensed.
