No, I had made no such assumption. I am interested only in the profile of an entire piece, as shown in the wonderful graphs that Hiro has been making. I'd like to be able to do the same thing, but none of the tools I downloaded (freeware, shareware, demos of $$$- ware) either worked or could analyze a file except by capturing playback from my soundcard (unless the UIs were just not set up in a way that allowed me to figure out how to use them to do what I wanted). I think you certainly recognize that if the spectrograph analyzer is looking at the playback of the file rather than the file itself that the result will include distortion introduced by my soundcard. Which is what I said all along, and, I thought, pretty clearly. Just goes to show that when one is speaking of a subject in which one lacks experience and expertise that it's easy to be misunderstood. -- David W.
