Problems solved by technology

[0003] However, at present, different reverberation processing devices have different numbers of internal filter combinations, resulting in different reverberation processing effects. The reverberation devices of some devices can achieve real-time reverberation processing, but cannot achieve ideal reverberation effects. The reverberator of some equipment can realize the natural sound of reverberation processing, and the effect of reverberation processing is good, but it cannot guarantee the real-time performance of reverberation processing, and cannot meet the real-time requirements in practical applications such as live broadcasting

Abstract

The embodiment of the invention discloses an audio reverberation processing method, device, equipment and storage medium. The method includes: obtaining the reverberation processing duration of the current filter combination, wherein at least three filters are connected to the current filter combination; if the reverberation processing duration is outside the standard reverberation processing duration range, adjusting The number of filters connected in the current filter combination to obtain a new filter combination. By obtaining the reverberation processing time of the current filter and comparing it with the standard reverberation processing time, it can be judged in time whether the current filter combination can realize real-time reverberation processing and achieve an ideal processing effect. If the reverberation is judged If the processing time is outside the standard reverberation processing time range, adjust the number of filters connected in the filter combination so that the obtained new filter combination can achieve real-time reverberation processing and achieve ideal processing effects.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of audio reverberation processing, and in particular, to an audio reverberation processing method, device, device, and storage medium. Background technique [0002] At present, after many devices receive the user's voice through the microphone, they will perform reverberation processing to make the sound have a sense of space and sound more real and natural. At present, the model used for reverberation processing of audio is mainly the Schroeder reverberation model and its improved model, using a combination of comb filter and all-pass filter to create the reverberation required for sufficient reflection density. [0003] However, at present, different reverberation processing devices have different numbers of internal filter combinations, resulting in different reverberation processing effects. The reverberation devices of some devices can achieve real-time reverberation processing, bu...
