Not sure about this !

Having checked out images in my archive of lossy / lossless spectrals I'm stumped by this one.
If you didn't know better you'd say lossy but the freq pic says otherwise.

Re: Not sure about this !

the highs are just noise... looks like maybe an fm broadcast captured to analog

lossy, but not necessarily digital data compression.

I have to disagree that this is lossy. I think it's just a low fidelity recording. Tony, on the FA if you change the FFT size to 512 and change Blackmann-Harris to Hanning what does it look like. Those are the settings I use in FA

I'd forgotten all about this one J. It goes back to April. Been so long I can't tell you what the artist or source is.
Doesn't matter.

FWIW; I find it easier to view the SA in black and white. More definition between the Hz ! In colour I find it too difficult to read the grading.
