The invention discloses a noise processing method, which includes: dividing the time domain signal of each window of the frequency to be denoised into frames; wherein, the length of each frame is several sample points; dividing the sample points into several interval, and calculate the interval energy of each interval; determine whether the interval energy of the continuous interval meets the preset short-term non-stationary noise identification condition; respond to the judgment result meeting the preset short-term non-stationary noise identification condition, extract the described The ADSR feature of the continuous interval, and determine the corresponding noise elimination method according to the extracted ADSR feature. The embodiment of the present invention also provides a noise processing device, equipment and storage medium to effectively solve the problem that the prior art cannot quickly identify noises and thus cannot eliminate these noises well.
Description
technical field [0001] The present invention relates to the technical field of sound processing, in particular to a noise processing method, device, equipment and storage medium. Background technique [0002] Generally speaking, noise can be divided into three categories: stationary noise, short-term stationary noise, and short-term non-stationary noise. Stationary noise means that the mean value is constant, the correlation function is only related to the time difference, and its characteristics remain basically unchanged. Short-term stationary noise means that it can remain stable for a short period of time, such as speech signals. Short-duration non-stationary noise is noise that does not remain stationary for any period of time. [0003] Short-term non-stationary noises are very common in real life, such as opening and closing doors, putting things down, sounds from percussion music, and so on. In addition to short-term non-stationarity, this kind of noise also has on...
