Hello Maree, When you have all the tracks added, tab to the track list and press Ctrl-A to select all. Then when you tab some more you'll find a button "Properties" . That brings up a two-page dialog, one of which allows you to affect how the audio gets filtered, normalized, reverbed, etc. Also even without that, there's always a normalize all tracks checkbox available to allow you to have them all set to the same basic level. I don't see any control over compression, etc. but perhaps you can mess around with these settings, and burn off a few CDs until you find something you like.

I am puzzled why the vocal and sax solos on both of these sound compressed, really low in the mix and almost a ghostly reverb in some tracks when I play the disk on a variety of regular sound systems only to get the same result. I don't know much but I'm just wondering if there should be some level that I should be checking in 'sndvol32' or some other dialog. I am still using JAWS 5.10 and cannot check the default setting in sndvol32, if indeed this is what I should be looking at, can anyone tell me what the default setting should be or where I should be looking to find a solution 'cos it's driving me mad, or is it my old analog ears? The files don't have that sound if I play them from my hard drive, only the compilation CD itself. So it must be something I'm doing wrong in the disk burning process I guess. Pretty please, what could it be? Marée
