Normalization is just simple amplification by a
constant factor. The factor is calculated so that the
highest peak in the normalized audio will be at some
user-determined target level (typically, the target defaults to
"maximum", e.g. 32767 for signed 16-bit audio... or sometimes
a dB or two below maximum, I guess to avoid clipping DACs).
So if you think about it, normalization is always
both A and B :-)

If these spikes aren't clips, maybe I can
normalize
and close the level gap between the spikes and
the
average signal. I'll try that but suspect it won't
do
the job.
Normalizing won't change the relative levels of the
spikes
and the average at all.
