Bit rates for music are usually 192 kbit for good quality, 256 kbit and more for
excellent quality. 128 kbit are sufficient for Internet streaming and speech (in
mono).
Encoder quality: The included MP3 encoder can operate in three "gears":
"Fast" mode is especially fast, "highest" mode is very powerful to achieve the
best sound possible and takes a little more time, and the third "gear" is a
compromise between the two.
Padding options: Leave this setting on ISO padding, unless you detect
undesired pauses at the beginning of tracks during playback on certain
players.
Encoder settings: These are optimizations that will only be used for low bit
rates (smaller than 128 kbit) to reduce the file size. "Permit intensity stereo
coding" or "mid/size stereo coding" will save certain parts of the audio
material in mono to save bandwidth. The extend to which sound quality is
improved depends on the material. "Permit mixdown in mono" allows the
encoder to save in mono if it detects that the content of both stereo channels
is identical, even if stereo was set as output format (e.g. introduction within a
radio program).
Content options: The "Use CRC check" option adds an internal checksum to
the MP3 file which checks whether the MP3 file is complete. The other options
(private, copyright, original) are merely for your own labeling system, as they
won't be evaluated in any form.
VBR: VBR (variable bit rate) adjusts the bit rate to the audio material, so a
lower bit rate will be used for quiet parts. Therefore, VBR files are smaller than
files of comparable quality without VBR. Thus, a constant bit rate setting
doesn't exist, but rather a quality setting. Not all playback programs and
devices can use VBR properly; problems may occur when displaying the track
length and during winding (seeking).
