Well, this is my last statement on this subject, but in an application that does spectrographic analysis and requires that you choose an input sound device (as more than one of the programs I tested did require) it is pretty clear that the analysis app is capturing the audio output, just like Audacity and other audio capture programs. These apps lacked a FILE OPEN capability that would have allowed me to choose a file for analysis without capturing the soundcard output. > . . .

Well, Johannes, you're just WRONG, WRONG, WRONG. These applications had no capability of opening a file. All they could do was listen to a stream of audio from the soundcard. Now, more than one of the apps *did* have the ability to open WAV files, but I wanted to analyze MP3 files, so those were of no use to me. Those, presumably, would not have involved my soundcard. But in the case of the ones I've been talking about, the soundcard *was* involved, whether you are able to conceive of that being the case or not. YOU ARE JUST WRONG HERE. -- David W.
