Music reproducing apparatus
In a music reproducing apparatus for converting audio data into audio data of different data format so as to reproduce it, gapless reproduction and cross-fade reproduction are performed in a switching manner, and generation of a noise at time of the gapless reproduction is repressed. When a reproducing section performs the gapless reproduction, a converting section performs conversion into PCM data to be reproduced latterly using a buffer used for conversion into the PCM data to be reproduced formerly. Further, when the reproducing section performs the cross-fade reproduction, the converting section generates a buffer different from the buffer used for the conversion into the PCM data to be reproduced formerly in a storage section, and performs the conversion into the PCM data to be reproduced latterly using the generated buffer.
1. A music reproducing apparatus for performing gapless reproduction for reproducing two audio data sequentially and seamlessly and cross-fade reproduction for reproducing two audio data while performing fade-in and fade-out, the apparatus comprising:
a converting section for generating a buffer in a storage section, and converting first audio data into second audio data of different data format using the generated buffer; and
a reproducing section for performing the gapless reproduction and the cross-fade reproduction on the second audio data, wherein
the converting section
performs conversion into the second audio data to be reproduced latterly using the buffer used for the conversion into the second audio data to be reproduced formerly when the reproducing section performs the gapless reproduction,
generates a buffer different from the buffer used for the conversion into the second audio data to be reproduced formerly in the storage section, and performs the conversion into the second audio data to be produced latterly using the generated buffer when the reproducing section performs the cross-fade reproduction.
2. The music reproducing apparatus according to claim 1 , wherein the converting section
stores a sampling frequency of the first audio data converted into the second audio data in the storage section,
when the sampling frequency stored in the storage section is different from the sampling frequency of the first audio data converted into the second audio data, generates a buffer that is different from the buffer used for the conversion into the second audio data to be reproduced formerly in the storage section even in a case where the reproducing section performs the gapless reproduction, and performs the conversion into the second audio data to be reproduced latterly using the generated buffer.
3. The music reproducing apparatus according to claim 1 , wherein when the converting section does not perform the conversion into the second audio data to be reproduced formerly, the converting section generates a buffer in the storage section even in the case where the reproducing section performs the gapless reproduction, and performs the conversion into the second audio data to be reproduced latterly using the generated buffer.
4. The music reproducing apparatus according to claim 1 , wherein the first audio data is DSD data,
the second audio data is PCM data.
5. A storage medium in which a music reproducing program is stored, the music reproducing program allows a computer to function as a music reproducing apparatus for performing gapless reproduction for reproducing two audio data sequentially and seamlessly and
cross-fade reproduction for reproducing two audio data while performing fade-in and fade-out, the program allowing
the computer to function as:
a converting section for generating a buffer in a storage section, and converting first audio data into second audio data of different data format using the generated buffer; and
a reproducing section for performing the gapless reproduction and the cross-fade reproduction on the second audio data,
the converting section
performs conversion into the second audio data to be reproduced latterly using the buffer used for the conversion into the second audio data to be reproduced formerly when the reproducing section performs the gapless reproduction,
generates a buffer different from the buffer used for the conversion into the second audio data to be reproduced formerly in the storage section, and performs the conversion into the second audio data to be reproduced latterly using the generated buffer when the reproducing section performs the cross-fade reproduction.
