Problems solved by technology
The distortion is mainly manifested in the following parts: Playing a piece of audio on an audio playback device (such as a stereo), converting from a digital signal to an analog signal will cause waveform distortion; the audio signal propagates in the air and will be affected by environmental noise, obstacles, etc. The resulting echo and other sound interference cause distortion; audio signals are filtered through electronic components such as capacitors, inductors, and operational amplifiers during recording (such as microphones), and analog-to-digital conversion and sampling cause distortion

Embodiment Construction
[0026] The technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention.
[0027] It should be noted that like numerals and letters denote similar items in the following figures, therefore, once an item is defined in one figure, it does not require further definition and explanation in subsequent figures.
[0028] In the description of the present invention, it should be noted that the terms "first", "second", "third" and so on are only used to distinguish descriptions, and should not be understood as indicating or implying relative importance. Furthermore, the term "and / or" in this application is only an association relationship describing associated objects, which means that there may be three kinds of relationships, for example, A and / or B, which may mean that A exists alone, and A and B exist simultaneously. B, there are three situations of B alone.

The invention relates to an analog audio distortion method and device, a server and a storage medium, and belongs to the technical field of data processing. The analog audio distortion method includesthe following steps that an original audio file is decoded, and audio data features are obtained from decoded data; the audio data features are subjected to sparsity expansion, and target data features are obtained; the target data features are processed by using a pre-trained network model, and distortion audio features are obtained; the distortion audio features are encoded, and a distortion audio file is obtained. By the method, a large number of distortion audio files can be generated quickly based on the original audio files without recording, the efficiency of obtaining the distortion audio files is improved, and thus the cost of human resources is saved.
Description
technical field [0001] The invention belongs to the technical field of data processing, and in particular relates to an analog audio distortion method, device, server and storage medium. Background technique [0002] Recording in a physical environment will cause audio distortion, that is, the waveform of the audio signal after recording is slightly different from the original audio signal waveform. The distortion is mainly manifested in the following parts: Playing a piece of audio on an audio playback device (such as a stereo), converting from a digital signal to an analog signal will cause waveform distortion; the audio signal propagates in the air and will be affected by environmental noise, obstacles, etc. The resulting echo and other sound interference lead to distortion; audio signals (such as microphones) are filtered through electronic components such as capacitors, inductors, and operational amplifiers during recording, and analog-to-digital conversion and sampling...
