The invention provides a DAB link optimization method, device and equipment, and the method comprises the steps: scanning all audio
broadcasting frequencies according to the identification coding information of a current radio
station when monitoring that a radio
station list is updated, and obtaining candidate radio stations; after the candidate radio stations are stored in a preset audio buffer area, whether the coding formats of the candidate radio stations are target coding formats or not is judged; if not, performing
code conversion on the candidate radio
station according to a target coding format to obtain a first preprocessed radio station; performing
timestamp alignment on the current audio
stream and the candidate audio
stream to obtain a second preprocessed radio station; and when monitoring that the broadcast
signal parameter of the current radio station is sharply degraded, immediately starting the second preprocessed radio station. According to the method, candidate radio stations are scanned and screened in advance, and preprocessing of
code conversion and
timestamp alignment is completed; and when the broadcast
signal parameters are sharply degraded, the radio station realizes rapid switching after the second preprocessing is immediately started, so that auditory interruption can be eliminated, and the switching reliability is improved.
