Sparse Gaussian Process Audio Source Separation Using Spectrum Priors in the Time-domain
Sparse Gaussian Process Audio Source Separation Using Spectrum Priors in the Time-domain
Gaussian process (GP) audio source separation is a time- domain approach that circumvents the inherent phase approx- imation issue of spectrogram based methods. Furthermore, through its kernel, GPs elegantly incorporate prior knowl- edge about the sources into the separation model. Despite these compelling advantages, the computational complexity of GP inference …
