Re: What is diginoise?

Okay, the diginoise (of this kind as with all others) is definitely obvious to the ear. So I guess that in the case where I read about someone using a wave editor to verify it, analysis was needed because it was at a lower volume.

Five: what are the screenshots of (ie. what type of analysis)? #1 and #2 are the same only with differing time scales. And what program did you use to do this? I tried playing around with audacity to reproduce something similar but it didn't work.

Anybody know of any good beginners guides to sound analysis (basic tools/kinds, scope, interpretation)? Or do I have to crack a DSP textbookto learn about this?

Thx.

The diginoise looks just wrong under close examination in a wav editor. the prog I'm using for FA is cooledit pro 2.1 aka adobe audition. The program for the FA is Audacity (select some music, go to view>plot spectrum and it gives the best FA). To see how to get a better SA with Audacity check here.

Yes, spectral screenshots are the same thing with different time scales. When you zoom in on SA to about 2 seconds lossy sources will show giveaway block shapes that aren't always visible when zoomed out.
