An MP3 and WMA Primer D-3
Memory and Audio
Quality
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.
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.
