AMBMAN normalise

NORMALISE:  adjusts a file's volume so that the peak
volume is a set figure (-1.5dB unless you opt for another
value).
The process is verbose due to underlying snags in the
scripts called. This is being worked on.
Multiple processing of sound files beyond the essential
is not recommended, and thus normalising should generally
only be done once at the end of processing.
