About encoded audio
Applications like Windows Media Player and Nokia Audio
Manager encode audio files with codecs like WMA or MP3
to save storage space. The encoding is done by removing
those parts of the audio signal that are not audible or only
barely audible by human ear.
Regardless of the encoder and codec quality, the sound
quality of the resulting file is not as good as the original.
The basic codecs supported by this device are AAC, WMA,
and MP3. All of these have different variations.
Bitrates
When encoding audio, the quality of the resulting sound
depends on the sample rate and bit rate used for the encoding.
Sample rate is expressed as thousands of samples per
second (kHz), and for CD music the sample rate is fixed at
44.1 kHz. Bit rate is expressed as kilobits per second (kb/s).
The higher the bitrate, the better the sound quality.
The required quality level may depend on your demands,
the headphones used, and the surrounding noise. For MP3s
a bitrate between 128 and 192 kb/s usually gives results

WMA or AAC generally gives a similar result as MP3 with
one step lower bitrate (96-160 kb/s). Variations of AAC,
such as AAC+ and enhanced AAC+ (eAAC+) provide CD
