We present a new method for synchronization of multiple independent A/D converters for microphone array processing. Since the spectrum obtained in each channel becomes a stretched version of the source spectrum, we construct a probabilistic generative model of spectrum stretch. Synchronization is realized by solving the inverse problem of the probabilistic generative model.
