goertzel-filter implementation
WebAudio Node that implements a goertzel filter
Fast frequency detection using the Goertzel algorithm
Goertzel algorithm implementation
A small no_std crate to compute THD using the Goertzel algorithm
High-performance, no_std, MCU-friendly FFT, DCT, DST, Hartley, Wavelet, STFT, and more. Stack-only, SIMD, and batch transforms for embedded and scientific Rust.
SSTV (Slow-Scan Television) encoding and decoding library for HAM radio
Pure Rust Energy Systems Simulation & Optimization Library
High-performance Morse code decoder with 100% test suite accuracy
Pure-Rust WSJT-family decoders + synthesisers (FT8 FT4 FST4 WSPR JT9 JT65 Q65) behind a zero-cost Protocol trait. Host (rustfft) or no_std embedded (ESP32-S3, RP2350, Cortex-M) via a pluggable FFT backend; fixed-point hot path for FPU-less MCUs. Ships with embedded-poc/m5stack-s3-app, a working M5StickS3 FT8 controller (LCD UI, BLE CI-V to IC-705, acoustic mic, QSO FSM) decoding real on-air signals in ~1.2 s post-SlotEnd on Xtensa LX7.
