Title:
AUDIO ENHANCEMENT METHOD AND APPARATUS, AND ELECTRONIC DEVICE AND READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/226839
Kind Code:
A1
Abstract:
An audio enhancement method and apparatus, which belong to the field of audio processing. The method comprises: acquiring a target complex spectrum feature of initial audio data, wherein the initial audio data comprises audio data of at least two audio channels (101, 201); inputting the target complex spectrum feature into an encoder (610) of a target model (600), so as to obtain a first feature (102, 202, 302); inputting the first feature into a frequency-domain model of the target model (600), and performing frequency-domain feature extraction on the first feature, so as to obtain a second feature (103, 303); inputting the second feature into a time-domain model of the target model (600), and performing time-domain feature extraction on the second feature, so as to obtain a third feature (104, 204, 304); fusing the second feature with the third feature, and inputting the fused feature into a decoder (630) of the target model (600), so as to obtain a complex masking value (105, 205); and generating enhanced audio data according to the complex masking value (106).
