I have recorded a number of tracks that will go together on a CD (or MP3 download).

How can I make sure that they play at more or less the same volume? Does Amadeus Pro provide some statistic that will help me know whether, on average, two tracks will play at the same volume. For example, could it be Average RMS power under Waveform Statistics?

And while I'm asking for such a statistic, is there a standard level at which each track should play?

Thanks very much.

Years ago I wrote up and published somewhere on the hairersoft site how
I did this job but I have no idea how to find it -- there was some
special place for usage articles and I don't know how to find it.

At that time I used a specialized program to generate the average value
of the tracks that was frequency-weighted but I can't see any reason
that the the rms for the track won't work.

Basically what I did was for each track I generated the peak value and
the rms value in db. I then went through and found the biggest
difference between the peak and rms value -- say 20 dB. I then
normalized every signal so that its average value was -20 dB, which
guarantees that no track will have its maximun greater than 0 dB. I then
burned a CD and listened to it. I ended up changing a couple of tracks
by 2-3 dB.

For what I was working with (classical voice -- Vivaldi, Mozart,
spirituals, etc.) the technique worked quite nicely

Thanks for your response, Chuck. Sounds like a nice solution. I should have mentioned, for the sake of completeness, that what I'm doing is spoken word.

So to confirm (I'm new at this), you're suggesting that a reasonable average RMS power for a track is -20db (after the precaution that you're suggesting). Correct?

No -- not at all; that value was just an example.

Go through your clips and find the rms average and the peak. Then
normalize to the largest difference value. That way you can be sure
that 1) your output is as high as possible and 2) you have no clipping.

For spoken word, you might well want to use some sort of compression or
leveling first.
