Yeah, thanks for the explanation. I'm still a little bit confused by the use of the PPM meter...

When you say "Peak hold" meter what do you mean? I know that SoundForge has a number at the top that tells the highest peak in the recording...so, for instance, as the song plays, it lets you know when the highest peak occurs. So, at the beginning the song may be at -2.3 DB and then by the end, the peak meter detected the highest peak at -0.2 I'm assuming since it didn't go over zero, that that is a safe level of volume?
