Abstract
An electronic device is provided. The electronic device includes: a first processing unit; a storage unit, configured to store at least one audio file; a first memory unit; and a modulator-demodulator (modem), configured to perform audio processing of the electronic device during a phone call, wherein when the electronic device is used to play the audio file, the first processing unit reads the audio file from the storage unit, retrieves header information of the audio file, and writes the audio file into the first memory unit, wherein the modem accesses the audio file stored in the first memory unit based on the header information, and performs audio decoding on the audio file.
