I've never normalized a track. Can normalization hold
a -0.5db peak to -0.5 while it pushes a -12db valley
up to -6db?
No, normalization only scales the data points so that relative amplitude
is maintained. The WHOLE file is scaled so that -3db becomes -1db, -6db
becomes -5db, -9db becomes -7db, etc. This does raise the overall volume
by 2db, but it won't normally get you all that much volume if there are
a lot of dynamics in the file or else you'll clip those peaks.
That's "peak" normalization. There is also "RMS" normalization
which
doesn't scale everything equally.
