摘要： To resolve volume shortage of middle and high band of speaker reproduction sound. 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： To realize active control ground that sets inverted output of an amplification circuit to ground with simple configuration.A DAP 1 comprises a positive side DAC 7 that D/A-converts digital audio data into analog audio data, a positive side amplification circuit 9 that amplifies the analog audio data that the DAC 7 D/A-converts, a negative side DAC 8 that D/A-converts the digital audio data into the analog audio data, and a negative side amplification circuit 10 that amplifies the analog audio data that the DAC 8 D/A-converts, and a CPU 2. The CPU 2 mutes the DAC 8 in case of an ACG mode that sets output of the amplification circuit 10 to ground.
