  • Process and associated system for separating a specified audio component affected by reverberation and an audio background component from an audio mixture signal
    Patent number: 9711165
    Abstract: Processes are described herein for transforming an audio mixture for which a specific component is affected by reverberation, into a specific dry component (i.e. unaffected by the reverberation) and a background component. In the process described herein, the long-term effects of reverberation are explicitly taken into account by modelling the spectrogram of the specific component as the result of a matrix convolution along time between the spectrogram of the specific dry component and a reverberation matrix. Parameters of the model are estimated iteratively by minimizing a cost-function measuring the divergence between the spectrogram of the mixture signal and the model of the spectrogram of the mixture signal.

  • Process and associated system for separating a specified component and an audio background component from an audio mixture signal
    Patent number: 9633665
    Abstract: Processes are described herein for transforming an audio mixture signal data structure into a specified component data structure and a background component data structure. In the processes described herein, pitch differences between a guide signal and a dialogue component of an audio mixture signal are accounted for by explicit modeling.
