The Period-Modulated Harmonic Locked Loop (PM-HLL): A low-effort algorithm for rapid time-domain multi-periodicity estimation
Many speech and music analysis and processing schemes rely on an estimate of the fundamental frequency f0 of periodic signal components.Most established schemes apply rather unspecific signal models such as sinusoidal models to the estimation problem, which may limit time resolution and estimation accuracy.This study proposes a novel time-domain lo
