The following encoding options are available in the
Settings
area:
Drop-down menu
Constant Bit Rate
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.
Drop-down menu
Variable Bit Rate
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.
The following encoding options are available in the
Expert settings
area:
Drop-down menu
Encoding quality
Specifies the encoder quality. These settings specify whether you
