1. A low power audio play device, comprising:
- an audio processing unit configured to decode requested audio data, the audio processing unit buffering decoded requested audio data as buffered data; and
an audio output unit configured to play the buffered data when the buffered data in the audio processing unit are more than a predetermined amount,wherein a supply of power to hardware is configured to be cut off, except for power supplied to the audio output unit, while the buffered data are played.
