Abstract
A system includes memory storing instructions and a processing device coupled to the memory. The processing device executes the instructions to: receive a noisy audio signal from an audio receiver; pass the noisy audio signal through a deep neural network (DNN) model to generate a mask of a magnitude spectrogram of the noisy audio signal; retrieve a clean-only audio spectra and a noise-only spectra of one or more frequencies that exist within the noisy audio signal; generate a loss function as a combination of the clean-only audio spectra multiplied by the mask and the noise-only spectra multiplied by the mask; and train the DNN model while minimizing the loss function to generate a trained DNN model useable in audio noise suppression and dereverberation.
