    摘要： Problem: To resolve volume shortage of middle and high band of speaker reproduction sound.
    Solution: A DSP 4 performs LPF processing to extract low frequency component of an audio signal to which the first volume processing is performed, DRC processing to compress the audio signal to which the LPF processing is performed in case that the audio signal to which the LPF processing is performed is not less than a predetermined signal level, HPF processing to extract high frequency component of the audio signal to which the first volume processing is performed, second volume processing to attenuate the audio signal to which the HPF processing is performed based on the volume value that is received, and synthesis processing to synthesize the audio signal to which the DRC processing is performed and the audio signal to which the second volume processing is performed.

    摘要： Problem: To reduce signal output and wiring to a D/A converter (DAC).
    Solution: A DAP 1 comprises a DAC 7 that D/A-converts LR 2 channels digital audio data into LR 2 channels analog audio data, an amplification circuit 9 that amplifies the LR 2 channels analog audio data that the DAC 7 D/A-converts, a DAC 8 that D/A-converts the LR 2 channels digital audio data into the LR 2 channels analog audio data, and an amplification circuit 10 that amplifies inverted LR 2 channels analog audio data that the LR 2 channels analog audio data that the DAC 8 D/A-converts is inverted.
