Abstract
A method for adjusting audio frequency includes steps of: obtaining initial frequency and temporary data storage of audio data input to a buffering unit; performing a first adjustment procedure on initial frequency to obtain a first variation of temporary data storage corresponding to a first change of initial frequency; calculating a first frequency correction amount according to first variation and a first period of first adjustment procedure; adjusting initial frequency into first frequency according to first frequency correction amount; inputting first frequency into buffering unit; performing a second adjustment procedure on first frequency to obtain a second variation of temporary data storage corresponding to a second change of first frequency; calculating a second frequency correction amount according to second variation and a second period of second adjustment procedure, which first period is less than second period; and adjusting first frequency into target frequency according to second frequency correction amount.
