rusty_esp_audio-core
The pure half of the audio package: WAV, FLAC and ADPCM framing, a linear resampler, voice activity detection, and the fixed-block pipeline they feed — with no drivers, no allocator and no product types in it. no_std + alloc, forbid(unsafe).
Every codec path here is gated byte-identical against FFmpeg in both directions: our decode of their blocks equals their decode, and their decode of our file equals ours.
Where the evidence is
This crate is part of rusty_esp_audio. The
hardware results, the method lines and the open defects live in that package's
README and in
docs/LEDGER.md, where no number
appears without the run that produced it.
Part of Janus
Janus rebuilds the Espressif ESP32 and Arduino application portfolio as independent, memory-safe Rust packages — so a hardware maker can ship a device that the MATA home computer discovers, catalogs honestly, adopts under its own identity, and pays for. Ten packages, three layers, and the dependency direction never reverses.
| layer | packages |
|---|---|
| 0 — the vocabulary | rusty_esp_core · rusty_esp_dsp |
| 1 — the functions | rusty_esp_image · rusty_esp_video · rusty_esp_audio · rusty_esp_signal · rusty_esp_mid · rusty_esp_iroh |
| 2 — the surfaces | rusty_esp_arduino — the sketch facade · espino — the maker's CLI (not published) |
Every package is host-verified against an external oracle and keeps a ledger in which no number appears without the run that produced it. Five of seven device profiles have now run their kill tests on real silicon, three of them over a Wi-Fi network the board hosts itself.

rusty_alloc, the pure-Rust rebuild of
mimalloc that these firmwares run on, and
rusty_jpeg, the JPEG engine behind the
camera path — and our sister project
remade_ffmpeg_rs, a ground-up Rust rebuild of FFmpeg.
