This paper describes a new method for synchronizing microphones based on spectral warping in an asynchronous microphone array. In an audio signal observed by an asynchronous microphone array, two factors are involved: the time lag caused by a mismatch of the sampling rate and offset between microphones, and the modulation caused by differences in spatial transfer function between the sound source ...
