Abstract:
To represent and recover the constituent sources present in an audio mixture, informed source separation techniques are used. In particular, a universal spectral model (USM) is used to obtain a sparse time activation matrix for an individual audio source in the audio mixture. The indices of non-zero groups in the time activation matrix are encoded as the side information into a bitstream. The non-zero coefficients of the time activation matrix may also be encoded into the bitstream. At the decoder side, when the coefficients of the time activation matrix are included in the bitstream, the matrix can be decoded from the bitstream. Otherwise, the time activation matrix can be estimated from the audio mixture, the non-zero indices included in the bitstream, and the USM model. Given the time activation matrix, the constituent audio sources can be recovered based on the audio mixture and the USM model.
