There are many different RealAudio codecs. Each codec
is named according to the data rate it produces, and the type of content
for which it is best suited. The various codecs control most of the audio
parameters. You can only select volume adjustments in the Audio tab when
creating RealMedia or RealAudio files.
- The names of the RealAudio codecs refer to "Kbps" which is
Kilobits, not KiloBytes. Kilobits are 1/8 the size of KiloBytes. To do
an approximate conversion, just shift the decimal one place to the left.
For an accurate conversion, a calculator is useful.
- Generally, you should choose the codec that best describes your source
movie content and the data rate you desire.
