I have an mp3 I'm looking at:

Maximum: -1.330 dB
RMS: -19.545 dB

So far, so good. Then

Minimum: -3.134 dB

That doesn't make any sense. If the minimum were that high, how would you get an RMS that low?

Yes, that one baffles me. Go to that minimum sampe location and (obviously) you can see many samples that are much closer to zero !

Presumably this stat means something different to what it would seem.

What I think it does is that "minimum" is the farthest negative swing of the waveform. Thus if it swings all the way to the largest absolute value in the negative direction your "minimum" value will be 0 dB.

I seem to recall that older versions of SF worked the way you want it to, not this way, thought about turning in a tech support rqst on it but never got around to it.
