Claims11
An audio appliance for reading and processing digital audio data stored on an optical storage medium, comprising:
- a controlled drive device arranged for rotating the storage medium at a speed of rotation that is variable;
- optical sampling means for reading the audio data from the storage medium;
- a decompression module operatively connected to said optical sampling means for receiving the audio data read by said optical sampling means and for decompressing compressed audio data;
- and
- evaluation means for converting the digital audio data to analog audio data,
- wherein said speed of rotation is varied in response to a type of audio data being read by said optical sampling means.
