Abstract
Described herein is a method of processing an audio signal using a neural network or using a first and a second neural network. Described is further a method of training said neural network or of jointly training a set of said first and said second neural network. Moreover, described is a method of obtaining and transmitting a latent feature space representation of a perceptual domain audio signal using a neural network and a method of obtaining an audio signal from a latent feature space representation of a perceptual domain audio signal using a neural network. Described are also respective apparatuses and computer program products.
Claims1
A computer-implemented method of encoding an audio signal using a neural network, the method including the steps of:
- (a) obtaining a perceptual domain audio signal by applying a mask indicative of masking thresholds derived from a psychoacoustic model to the audio signal in an original signal domain;
- (b) inputting the perceptual domain audio signal into a neural network for mapping the perceptual domain audio signal to a latent feature space representation;
- (c) obtaining, as an output from the neural network, the latent feature space representation of the perceptual domain audio signal;
- and
- (d) outputting the latent feature space representation of the perceptual domain audio signal in a bitstream.
