Abstract
The present disclosure describes aspects of an end-to-end neural audio upsampler and bandwidth extender. In some aspects, the end-to-end neural audio upsampler and bandwidth extender is configured to receive an input signal having a first bandwidth and generate, using a first neural network model and in a time domain, a feature vector based on the input signal. The end-to-end neural audio upsampler and bandwidth extender is further configured to generate, using a second neural network model and in the time domain, an output signal based on the feature vector, where the output signal has a second bandwidth that is greater than the first bandwidth.
