User manual

Allow Downmix: This option makes it possible to
'downmix' the input signal from stereo to mono. This
has advantages when encoding a stereo source with
a very low data rate - and where encoding in mono
only would make sense.
Padding: Because mp3PRO blocks within an
mp3PRO file can be of different sizes and because
some mp3PRO player programs cannot cope with
MP3PRO different sized blocks, this option can be
selected to specify how to deal with mp3PRO blocks
of different size. The default setting with Nero is
'ISO', in other words, the procedure spelled out in
the ISO-MP3PRO standard. 'Always' and 'never', as
the names suggest, "top up" the differently sized
mp3PRO blocks (in every case or not at all).
Click on 'OK' if you are satisfied with the settings
and to close the dialog
Click on the ‘GO' button to begin encoding.
A window will appear and inform you of the progress
of the encoding procedure.
