Patent Searching and Data


Title:
AUDIO DENOISING METHOD AND APPARATUS, DEVICE AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/045779
Kind Code:
A1
Abstract:
An audio denoising method and apparatus, a device, a computer-readable storage medium, and a program product. The method comprises: obtaining audio data to be denoised (S101); estimating amplitude time-frequency masking of said audio data by using a preset real number network model to obtain a first-order enhanced amplitude spectrum corresponding to said audio data (S102); estimating complex time-frequency masking of said audio data by using a preset complex network model (S103); and determining denoising result audio data corresponding to said audio data by combining the first-order enhanced amplitude spectrum and the complex time-frequency masking (S104).
