A novel Time-Delay-of-Arrival estimation technique for multi-microphone audio processing

Multi-microphone speech enhancement requires knowledge of relative Time Delay of Arrival (TDOA) of the desired acoustic source at microphones. This paper presents a novel TDOA estimation method, Steered Null Error PHAse Transform (SNE-PHAT), which exploits null-steering to improve estimation robustn…
