The use of psychoacoustical masking models for audio coding applications has been wide spread over the past decades. In such applications, it is typically assumed that the original input signal serves as a masker for the distortions that are introduced by the lossy coding method that is used. Such masking models are based on the peripheral bandpass(More)
We propose a new approach for modeling auditory masking based on gammatone filters for application areas including speech/audio coding and audio watermarking. Besides the use of gammatone filters, this model differs from existing audio coding psychoacoustical models (e.g., the ones used in MPEG), in taking into account the contribution of a range of filters(More)
