Abstract

In a smartphone that outputs PCM data and DSD data of different data format from PCM data to a USB DAC, to prevent generation of noises from the USB DAC when the smartphone accepts stopping instruction of outputting digital audio data to the USB DAC while outputting DSD data to the USB DAC.
A controller 11 outputs mute data representing silence of DSD data to a USB DAC 2 when it accepts pausing instruction while outputting DSD data to the USB DAC 2.

First claim

What is claimed is:

1. A music reproducing apparatus comprising: a controller for outputting digital audio data that includes first digital audio data and second digital audio data of different data format from the first digital audio data to a D/A converter,
for accepting stopping instruction of outputting the digital audio data to the D/A converter, and
for controlling the D/A converter, wherein
the controller outputs the second digital audio data to the D/A converter to be converted as mute audio data representing silence when it accepts the stopping instruction while outputting the second digital audio data to the D/A converter, and
stops the D/A converter after it starts outputting the mute audio data to the D/A converter and predetermined time passes.

2. The music reproducing apparatus according to claim 1 , wherein the controller stops the D/A converter when it accepts the stopping instruction while outputting the first digital audio data to the D/A converter.

3. The music reproducing apparatus according to claim 1 , further comprising: a display section, wherein
the controller further controls display of the display section, and allows the display section to display that outputting the digital audio data to the D/A converter is in a stopping state when it accepts the stopping instruction.

4. The music reproducing apparatus according to claim 1 , wherein the controller stores a marker that includes information representing it is the second digital audio data and the second digital audio data in frames of the first digital audio data and outputs the marker and the second digital audio data to the D/A converter.

5. The music reproducing apparatus according to claim 1 , wherein the first digital audio data is PCM data, and
the second digital audio data is DSD data.

6. A non-transitory computer-readable storage medium in which a music reproducing program is stored, the music reproducing program allows a controller of a computer to output digital audio data that includes first digital audio data and second digital audio data of different data format from the first digital audio data to a D/A converter,
to accept stopping instruction of outputting the digital audio data to the D/A converter, and
to control the D/A converter,
the music reproducing program allows the controller to output the second digital audio data to the D/A converter to be converted as mute audio data representing silence when it allows the controller to accept the stopping instruction while allowing the controller to output the second digital audio data to the D/A converter, and
to stop the D/A converter after it starts outputting the mute audio data to the D/A converter and predetermined time passes.
