I am now (beginning with Black Sabbath 1981-11-19 Canadian Assault) including the results of a (very) basic test for lossiness in the download bundle (.rar file). Specifically, I am using Traders Little Helper (TLH) to test for CDDA vs. MPEG. This is included as a screenshot file, named “TLH test.png”.
For bootlegs where I physically own the actual bootleg (whether CD or CD-R), I rip directly to FLAC5, and do not in anyway modify the transferred recording. However, we all know that some bootlegs are lossy sourced.
I am making this change (the addition of the TLH screenshot) primarily so that I, myself, can have some sense of how likely the bootleg is to be truly lossless. Also, perhaps others will wish to be aware of this information.
I know that this is an extremely basic test only–not as good as a spectral analysis (or whatever else)… But hopefully this is of some value, compared to not providing any information on lossless vs. lossiness of each bootleg.
On a related note: I have a number of Ian Gillan-era Black Sabbath (1983-1984) commerical bootlegs that I am beginning to post. It is disappointing that most (all?) of these bootlegs are lossy 🙁
