Abstract
Methods, systems, and apparatus, including computer programs encoded on computer storage media relate to a method for audio super resolution. The system receives an audio signal. When the sampling rate of the audio signal is below a sampling rate threshold or the frequency range of the audio signal is below a frequency range threshold, the audio signal is input to an audio super resolution model comprising a machine learning model. The audio signal is processed by the audio super resolution model to generate a synthetic audio signal with a wider frequency range than the frequency range of the audio signal.
