Memory and Audio
Quality
For optimal audio quality,
it is recommended that
you set your encoding
bitrate at 128 Kbps for
MP3 files and 64 Kbps
for WMA files (see
Figure D-1) when you
create them from audio
CDs.
The amount of memory available and the quality of the MP3or WMA file are related. The higher the
quality required, the higher the bitrate needed. This leads to more data storage and memory
requirements. The amount of memory required in your Creative TravelSound MP3 player is
proportionate to the audio playback time.
