[0.1.1] - 2026-04-24

Changed

WASM: ~13-15x speedup in ResonatorBank::process_sample / process_samples at 88-880 bins, by recovering autovectorization that was defeated by f32::mul_add lowering to per-lane fmaf calls on wasm32+simd128. Diagnosis by @pengowray (#1).

[Python 0.1.1] - 2026-04-22

Changed

Linux and Windows x86_64 wheels now target x86-64-v3 (Haswell, 2013+) to enable AVX2 + FMA auto-vectorization in the resonator hot loop. On Linux, this is typically a 20-50x speedup over the 0.1.0 wheel. Users on pre-Haswell CPUs should install from sdist with custom RUSTFLAGS.

[0.1.0] - 2026-04-21

Added

ResonatorBank and Resonator types implementing the Resonate algorithm for low-latency spectral analysis.
Streaming (process_samples) and one-shot (resonate) processing modes.
heuristic_alpha / heuristic_alphas, alpha_from_tau / tau_from_alpha, midi_to_hz helpers.
Python bindings via PyO3.
WebAssembly bindings via wasm-bindgen.
