An audio processor circuit includes a storage circuit, a digital-to-analog converter circuit, and an amplifier circuit. The storage circuit is configured to store digital audio data from an electrical device. The digital-to-analog converter circuit is configured to convert the digital audio data from the storage circuit into an analog audio signal. The amplifier circuit is configured to provide an output audio signal to an audio playing circuit according to the analog audio signal. If a total data volume of the digital audio data stored in the storage circuit is not a multiple of a throughput or the total data volume of the digital audio data stored in the storage circuit is equal to or greater than an upper limit value, the amplifier circuit is turned off such that the amplifier circuit stops providing the output audio signal to the audio playing circuit.
