6.6.1.3 MP3 And MP3PRO Encoding Options
With Nero Burning ROM you can encode audio files of an Audio CD in MP3 and MP3PRO
formats. Set these options in the MP3PRO window that you can open in the Encode files
window via the Settings button. Ensure that you have selected MP3/MP3PRO as the Out-
put file format.
Selects a constant bit rate, i.e. the data flow per unit of time and
the quality of the saved data are the same over the entire audio
file. If the bit rate is small, less data is transferred. The file is then
small, but quality is lower. If the bit rate is high, more data is
transferred. The file size is then large, but the quality is high. The
default value of 128 for MP3 files is near CD quality.
Selects variable bit rate, i.e. the data flow per unit of time - and
thus the quantity of the saved data - adapts to the dynamics of
the audio file. The bit rate, for example, can be lowered at quieter
points in the track.
Select your desired quality level in the drop-down menu.
Specifies the encoder quality. These settings specify whether you
place more value on fast encoding (lowest/fastest) or more va-
lue on a superior psychoacoustic encoder model for the very best
results (highest/slowest).
Sets the original bit in the music file, which differentiates between
the copy and the original.
Check box selected: Original bit = 1, i.e. original.
Check box cleared: Original bit = 0, i.e. copy.
Sets the private bit in the music file. It is reserved for the user and
is only used for informational purposes.
Sets the copyright bit in the music file, which identifies protected
content.
Check box selected: Copyright bit = 1, i.e. protected.
Check box cleared: Copyright bit = 0, i.e. unprotected.
Also sets a checksum in the music file to ensure that transfer er-
rors are detected.
