Audio reverberation method and system

Abstract

An audio reverberation method includes: preprocessing an input audio signal to obtain a reverberation input signal; reverbing the reverberation input signal to generate an initial reverberation audio signal of a target scene; performing audio content analysis on the input audio signal to obtain an audio content feature of the input audio signal; determining a content-adaptive masking matrix based on the audio content feature; performing weighted mixing on the content-adaptive masking matrix and the initial reverberation audio signal to obtain a content-adaptive reverberation signal; and performing weighted mixing on the content-adaptive reverberation signal and the reverberation input signal according to a preset ratio to obtain a final reverberation audio signal. According to the embodiments of the present disclosure, audio signals with different audio content are adapted to different reverberation effects, avoiding the problem of distortion of the final reverberation audio signal.
