Sonon

⚡

100% Pure Safe Rust

Strictly zero external C audio libraries and `#![deny(unsafe_code)]` crate-wide. Runs bare-metal on microcontrollers, companion computers, or in browser WebAssembly.

🎯

Dynamic Rotor Notch Filtering

Telemetry-coupled IIR biquad notch bank locked to motor RPM telemetry, attenuating propeller blade pass frequencies by up to 40 dB.

🔊

Few-Shot Wake-Word Spotting

Banded Sakoe-Chiba DTW and DBA barycenter averaging enabling immediate 1-2 exemplar voice enrollment without gigabyte neural models.

🗣️

Physical Speech Synthesis

Klatt + Liljencrants-Fant physical glottal flow model and cascade vocal tract resonators delivering smooth coarticulation in WebAssembly.

🩺

Airframe Acoustic Health

Complex Morlet continuous wavelet transform (CWT) evaluating scale-wise kurtosis and blade flutter before structural failure.

🦇

Biosonar Echolocation & 3D Mapping

Active linear chirp compression and CA-CFAR echo detection providing 5-axis clearance and collision hazard guards in GPS-denied environments.

Multi-Platform Quickstart

typescript

// WebAssembly in Browser (JavaScript / TypeScript)
const { instance } = await WebAssembly.instantiateStreaming(fetch('sonon.wasm'));
const api = resolveSononWasmExports(instance);
const handle = api.sonon_wasm_create(16000, 512, 160, 13);

// Register Custom Word from Live Microphone Voice Recording
api.sonon_wasm_set_string_bytes("falcon");
api.sonon_wasm_set_input_samples(recordedVoiceSamples);
api.sonon_wasm_enroll_audio_buffer(handle, 6, recordedVoiceSamples.length, 0.58);

// Streaming Ingestion via AudioWorkletNode
const detections = api.sonon_wasm_ingest(handle, samples.length);
if (detections > 0) {
    const keyword = api.sonon_wasm_get_last_keyword();
    console.log(`Detected: ${keyword}`);
}

rust

// Pure Safe Rust Native Ingestion
use sonon::engine::SononEngine;

let mut engine = SononEngine::new(16_000, 512, 160, 13)?;
engine.enable_telemetry_coupled_notch(4, 2); // 4 blades, 2 harmonics
engine.update_motor_rpm(5_400.0);

let samples: [f32; 160] = read_mic_buffer();
if let Some(event) = engine.process_frame(&samples)? {
    println!("Spotting Event: {} (confidence: {:.2})", event.keyword, event.confidence);
