Title:
METHOD AND DEVICE FOR DETERMINING DELAY OF AUDIO
Document Type and Number:
WIPO Patent Application WO/2018/019181
Kind Code:
A1
Abstract:
A method and device for determining the delay of an audio. The method comprises: obtaining inputted audios to be adjusted, which are a first audio and a second audio (101); extracting a first sub-fingerprint sequence of the first audio and a second sub-fingerprint sequence of the second audio (102), the first sub-fingerprint sequence comprising at least one first sub-fingerprint, and the second sub-fingerprint sequence comprising at least one second sub-fingerprint; determining multiple similarities between the first sub-fingerprint sequence and the second sub-fingerprint sequence (103); determining the matching degree between the first sub-fingerprint sequence and the second sub-fingerprint sequence according to the multiple similarities (104); and determining the delay of the second audio relative to the first audio according to the matching degree (105). By means of the method and the device, the computing precision can be improved, and accordingly the effect of delay compensation can be improved and the phenomena of sound overlapping can be reduced.
