Osclet

Osclet is a high-performance Rust library for Discrete Wavelet Transform (DWT) and Inverse DWT (IDWT). It supports both f32 and f64 types and provides optimized implementations for modern architectures including ARM NEON (AArch64) and x86 SIMD. Osclet is designed for signal processing, audio analysis, and image compression workloads where speed and precision are critical.

Features

• Multi-level DWT decomposition for f32 and f64 signals.
• Support for Daubechies wavelets of various orders (db2, db3, db4, etc.).
• Optimized for ARM NEON and x86 SIMD instructions.
• Thread-safe and can be used in parallel contexts (Send + Sync).
• Customizable border modes for signal padding

let signal: Vec<f64> = vec![1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0];
let dwt_executor = Osclet::make_daubechies_f64(DaubechiesFamily::Db4, BorderMode::Wrap);

let dwt = dwt_executor.dwt(&signal, 1).unwrap();
println!("Approximation coefficients: {:?}", dwt.approx);
println!("Detail coefficients: {:?}", dwt.detail);
