* PC needs to be able to handle wav files and output digital audio signal at Sampling Frequency 44.1 kHz.
* For wav-compatible PCs which do not output audio signal at the above specification,
use a commercially-available USB-AUDIO interface unit. e.g. Onkyo-made ND-S1
* Set Sampling frequency to 44.1 kHz and also set Volume to Maximum.
For further information, please see Owner's manual of your PC.
* Instead of PC, CD players with DIGITAL output terminal can be used.
Note: CD players need to output digital audio signal at 44.1 kHz of Sampling frequency.
Some CD players and DVD players are not suitable for update because they process audio signal to output.
Burn a CD-R as music disc.
