Lossy or lossless? Any opinions?

Hi, wonder if anyone can help determine if this is minidisc or DAT sourced?
Thanks

it is hard to say (for me, anyway) based on these pics, since the spectreal screenshots only show up to 8kHz which is usually way below the cutoff if there is any cutoff - we need to see everything up to 22.05 kHz (or 24 kHz respectively, and in this frequency analysis I don't see the kHz value. Any chance that you share a short (2 seconds would be enough) flac audio sample instead?
it also depends on the sample rate of the dat. a dat with a 32kHz sample rate will appear lossy (and actually IS lossy, in a way, because 32kHz is substandard now), and i would probably not be able to tell the difference from minidisc or mp3. a dat recording at 48 kHz, however, would be perfectly lossless.

Hi, thanks for your reply, here's a sample if that helps

Thanks, yes, this helps. This is not an exact science, but here's my 2 cents:
If I didn't know anything about this recording, I would say it has to be either lossy-sourced or crudely denoised. That's what the "lego block" pattern at the border of the colored and the black areas in the attached screenshot tells us. If you know that this is either from DAT or from MiniDisc and that it hasn't been denoised, I am 99% sure it is from MiniDisc.

Ok that's great, thanks for your help . I was told it was DAT0 but had suspicions that it may be from a md source instead.

I agree it is MD. scroll down this thread.
