The invention discloses an audio processing method and device, computer equipment and a storage medium, and relates to the technical field of audio processing. The method comprises the steps that first audio data with the sampling rate being the first sampling rate are obtained; the first audio data are processed by a super-resolution model; and according to an output result of the super-resolution model, second audio data are obtained, wherein the sampling rate of the second audio data is the second sampling rate, and the second sampling rate is N times the first sampling rate. The model canmore accurately restore missing high-frequency components in the audio data with the low sampling rate, that is, the scheme of processing the audio data with the low sampling rate through the super-resolution model to obtain the audio data with the high sampling rate can significantly improve the audio processing effect.
Description
technical field [0001] The embodiments of the present application relate to the technical field of audio processing, and in particular, to an audio processing method, device, computer equipment, and storage medium. Background technique [0002] With the continuous development of digital music technology, users have higher and higher requirements for audio or video sound quality, which requires audio playback products (device or application program) to provide audio data with a higher sampling rate. [0003] In related technologies, a device or an application program that provides support for music playback can perform super-resolution processing on audio data with a low sampling rate through a preset audio data algorithm to obtain high-resolution audio data. For example, an audio data upsampling algorithm based on one-dimensional interpolation, or an audio data upsampling algorithm based on Fourier transform, may be used to perform upsampling processing on audio data with a ...
