Re: Is this mp3?
Doesn't look like mp3 to me either. FM? That black "line" of space in the top area I think indicates something, I think that it's an FM signal, but I could be wrong. Perhaps someone else will know what and if that's true that it even means anything.
On mp3s the freq will drop off at around 16khz. And the spectral view will show a hard line across the top where the sound cuts off, what is called a "haircut". Neither pic indicates these.
