Re: [Help] Needed about lossless/lossy audio frequency

Excuse me if this question sounds very silly for some of you who is specialized on taping and gear. But I am a little confused:

I have a few recordings of a band and I am trying to confirm if the sources I have tagged as "Lossless" is legit or if it's lossy version. I have installed AudioChecker and Spek (To analyze the frequency).

Example 1:
Source: AT853s > SP Battery Box w/ roll-off @ 69hz > Sharp MD-SR60
Transfer: Sony MDS-JB920 > coaxial S/PDIF > Hoontech ST-DBIII > SoundForge 5 > FLAC
Screenshot of Spek: https://ibb.co/fhD65J
NOTE: This was seeded by taper.

Example 2:
Equipament: MD: AT822 w/bass roll off > Aiwa AM-F65
Screenshot of Spek: https://ibb.co/mr3jsy
Note: Got it from the waves files from taper.


Final example:
MD: Home-made Binaural Mics > Sony MZ-R55
Note: Here's a screenshot of one of concerts I think is 100% legit: https://ibb.co/i6PUQJ

Conclusion: Why some of them seems to be lossy, even if it was seeded by the own taper? Is it due the mode it was recorded? Compressed MD or something like that?
if yes, is there any other way to analyze these to confirm if its a legit lossless or lossy?

There are a few shows released by tapers but when I check frequency it doesnt seems to be lossless or above 20Khz. What I am doing wrong?

Thanks for the help
Sure looks like lossy encoding from the screens, but to be absolutely certain you'd need a program with a better color map ("perceptually uniform colormap") and zoom in a little closer.
