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.

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.
