Title:
AUDIO PROCESSING METHOD AND APPARATUS, DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2024/077452
Kind Code:
A1
Abstract:
The present application relates to the field of audio processing, and discloses an audio processing method and apparatus, a device, and a storage medium. The method comprises: performing short-time Fourier transform on audio data to obtain a frequency domain data set, each time window in the frequency domain data set corresponding to a group of frequency domain data, and the frequency domain data comprising frequencies and amplitudes corresponding to the frequencies; calculating loudnesses according to the amplitudes in the frequency domain data set to obtain a first frequency domain loudness set, each time window in the first frequency domain loudness set corresponding to a group of frequency domain loudnesses, and the frequency domain loudnesses comprising frequencies and loudnesses corresponding to the frequencies; and using a fade-in and fade-out function to perform end-to-end windowing processing on the frequency domain loudnesses in each time window of the first frequency domain loudness set to obtain a second frequency domain loudness set. According to the method, the spectrogram better fits human hearing.
