Yes. So does that mean that the OP should use something like the
'stat' effect to find out the peak RMS level of the audio file,
then work out how much gain or attenuation is needed, then use
a 'gain' effect with that calculated value?
No, he should just use the gain effect. It adjusts both RMS and peak
values by the same amount because that is what happens when you
multiply
each sample by a fixed amount, which is what the gain effect does.
Yes, I understand that gain is gain, but he has to decide how much
gain to apply. If he's previously done that in terms of a pre-gain
peak level, but now wants to bring RMS levels to a certain point,
he surely has to find out what the file's RMS levels are first
then decide how much to modify it by?
