Bitrates
When encoding audio, the quality of the resulting sound
depends on the sample rate and bitrate 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. Bitrate is expressed as kilobits per second
(Kbps). The higher the bitrate, the better the sound quality.
The required quality level may depend on your demands,
the headsets 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). Variations of AAC,
such as AAC+ and enhanced AAC+ (eAAC+) provide CD
quality audio at bitrates as low as 48 Kbps. Classical music
and music with nuances usually require a higher bitrate
than basic pop music.
For speech or other sources where the quality of the sound
is less important than saving storage space, you can use
bitrates between 8 and 64 Kbps. At low bitrates WMA or
AAC generally gives better results than MP3.
Variable bitrate
Your device also supports variable bitrate (VBR). Variable
bitrate means that the bitrate of the encoding varies with the
complexity of the encoded material. When using VBR, the
encoding is optimized to preserve a constant audio quality
throughout the track, rather than losing quality for complex
music sections as with constant bitrate (CBR) encoding.
