{paper proposes a computational model of co-modulation masking release (CMR). It consists of two models, our auditory segregation model (model A) and the power spectrum model of masking (model B), and a selection process that selects one of their results. Model A extracts a sinusoidal signal using the outputs of multiple auditory filters and model B extracts a sinusoidal signal using the output of a single auditory filter. The selection process selects the sinusoidal signal with the lowest signal threshold from the two extracted signals. For both models, simulations similar to Hall et al.'s demonstrations were carried out. Simulation stimuli consisted of two types of noise masker, bandpassed random noise and AM bandpassed random noise. As a result, the signal threshold of the pure tone extracted using the proposed model shows the similar properties to Hall et al.'s demonstrations. The maximum amount of CMR in the proposed model is about 8 dB.
