A Survey of Enhanced Algorithm for SRP-PHAT
Jing Mingmin · Audio Engineering · 2012
A method,named steered response power phase-transform weighed(SRP-PHAT),is one of the most popular approaches for the microphone array sound source localization.The problem that the computation of SRP-PHAT is so expensive that it can't locate the sound source in real time is focused.Some efficient improvement approach such as traction(SRC),coarse-to-fine region contraction(CFRC),stochastic particle filtering(SPF),and so on are analyzed.Improvement methods for SRP-PHAT are summarized.
