Are these good or not? The one with the black at the top, I'm not sure about. Thanks

Looks lossy to me. Possibly an analogue recording of a lossy broadcast?

John, sometimes the SA in color can be deceiving. For most definite results it is best to try:

(thanks to dorrcoq for this tip):

It is useful to add a "Black & White" preset for spectral analysis, to do this:

Cool Edit pro 2.00
options > settings >

"colors" tab > "spectral" tab
Spectral High energy: black (highlight > change color)
Spectral Low Energy: white

Gamma: 0.4
thanks to range_hood for showing me this useful setting.

I still believe it's lossless. With the B&W settings you will know for sure.

You will be able to zoom in to 2 seconds give or take via the scroll wheel on the mouse.
