Crate slowrx 

slowrx

Pure-Rust SSTV decoder library — a port of slowrx by Oona Räisänen (OH2EIQ). Significant portions of the algorithms are translated from the C source. See the NOTICE file for full attribution and license preservation.

Status

0.5.x — V2.4 published. PD120/PD180/PD240 + Robot 24/36/72 + Scottie 1 / Scottie 2 / Scottie DX + Martin 1 / Martin 2 decoding from raw audio. PD120/PD180 validated against ARISS Dec-2017; Robot 36 validated against the ARISS Fram2 corpus (see tests/ariss_fram2_validation.md). Scottie and Martin families are synthetic round-trip-validated only — no Scottie or Martin reference WAVs available. The public API is #[non_exhaustive]-protected for additive growth as future mode-family epics land. See https://github.com/jasonherald/slowrx.rs/issues/9 for the V2 roadmap.

Example

use slowrx::SstvDecoder;

// Construct a decoder at the caller's audio sample rate.
let mut decoder = SstvDecoder::new(44_100)?;

// Feed audio chunks; consume any events that come back.
let audio = vec![0.0_f32; 1024];
let _events = decoder.process(&audio);
