About encoded audio

details. 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 used for the encoding. Sample
rate is expressed by kilobits per second (Kbps). The word
'bitrate' is also commonly used when talking about this
sample rate. 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 Kbps usually gives
results good enough for listening to pop music with your
device. WMA or AAC generally gives a similar result as
MP3 with one step lower bitrate (96-160 Kbps). Classical
