Talking about lossless

[Onclefritz]

There is some programs on the internet that can check if a lossless file is lossless or mp3. There is some:

Hum Audio Tools with a frequency analysis
Audacity with a frequency analysis
auCDtect Task Manager
Audiochecker not "Lossless Audio Checker"

and many more.

There is the results with a lossy show like 1986.07.06 - Copenhagen, Denmark - (2nd Source) Battery

What do you guys think? Usually there is a significant drop around 15000-16000 khz for mp3-sourced. The frequency analysis of 1986.09.18 - Sheffield, England seems lossless to me but with the others programs, its says lossy. I know that no programs can be perfect. Is the frequency analysis is only the best way? But a frequency analysis can be questionable and 2 person can have different opinions with the result. What do you guys use for programs?

If you have doubt about a show, please feel free to add results or pics, so we can talk about it.

What do you guys use for programs?

I use the spectral view in Adobe Audition and my eyes. But you can't always be sure. For example the minidisc recording format is actually lossy (If I understand correctly)
