Research lab for active noise control prototypes: offline FxLMS simulation, secondary-path IR measurement, and realtime experiments on Windows (WASAPI).
Author: Gleb Voronkov · Non-commercial research license · Status: research prototype, not a shipping consumer product.
Speaker-mode ANC is physically constrained by latency and the λ/10 quiet zone. This repo documents measured secondary-path delay on a laptop bench, correct FxLMS structure notes, and measurement protocols — the kind of engineering that prevents false “AI magic” claims.

Do not claim medical benefits or “room silence” from a phone speaker. Realistic near-term speaker ANC targets low-frequency drone near the device, often combined with masking.
