Re: Mp3 or Not???

It would be cool to see if we could get the same results from several fft programs by tinkering with settings.

this show it seems we need the sa to really see what's going on. the fa looks kinda flat in the highs but the drop isn't visible as with AnalFreq. EAC's sa you can see the drop at 16kHz at the highest fft setting, even tho it looks a little different.

the cutoff just above 16kHz in a straight line, this is the classic case of lossy source, since this is how 128kHz CBR mp3 displays. Also, the little legolike shapes visible when you zoom in with CEP indicates lossy.

I can't seem to figure out how to adjust the scale of the fa for cep... when I pull on the left bar it just moves up and down, and there's nothing in the advanced options I can see.

Oh, while I was doing this I discovered something.

I opened CEP, loaded in a short lossy-sourced .wav I had on my desktop and the fa looked like this:
