Question Lossy or Lossless?!?!?!?!?!!?

I just got these shows in a trade.
I'm sure on the source of most of them, but since I'm no expert, I'd just like another opinion to be sure

Re: Lossy or Lossless?!?!?!?!?!!?

all three look lossy

first two look like md (check the lineage)

the 3rd looks like default setting (128 cbr) mp3

The guy I traded with said he has the silvers for the first one and it is supposedly a SBD. I believe the second one is sourced from a radio broadcast.
As for the third one, I was pretty sure that was probably an MP3, just wanted to confirm it.

They all look lossy to me.

A SBD recording can also be lossy if it is taped as mp3.
If he got the silvers I think he has not transfered it to the pc as wave files or the one who taped it taped as mp3 or another lossy format and then burned it as wave.

Broadcasts in it self are lossy.

Re: Lossy or Lossless?!?!?!?!?!!?

older broadcasts are lossy in the sense that there is heavy dynamics compression and everything above 15kHz is filtered out... but the md compression has never been used for any broadcast I've ever come across, check the blocky 'parapets' up in the highest highs. That's where its visible, but MD will also dig in below its cutoff to discard more data it thinks you don't need. Everything slurs a little When we use the term 'lossy' on this board we're referring to digital endoders like lame (mp3), ogg vorbis, atrac (md), real, vqf, aac, ac3 (dvd), etc. We don't use it in the broad literal sense.

as far as modern broadcasts go I'm not sure when it started but 99% of mainstream radio worldwide is lossy encoded before broadcast.

We don't allow webcasts or digital satellite radio here since they're of wildly varying quality, leaning toward really low. But the modern analog broadcasts are still predictable in their level of frequency response so we still allow taping of radio from the open air, even though it is expected to be lossy in this day and age.

Tony, it is possible that the silver disc that was ripped from was pressed as lossy, that does happen sometimes. I've got 2 silvers that are sourced from mp3 in my collection

Other times MD gets in the lineage because when MD was a new thing nobody knew what lossy was, just that they could send a nice small digital copy on a minidisc instead of a cassette with the added noise... many shows have gone into circulation with this problem. Many of them have pure lossless counterparts in circulation so we try to keep the md sources off this tracker unless its been really well researched and known only to circulate with md in the lineage (eg Beatles A/B Road).

Thanks for helping me confirm what I thought, so they're all lossy, shame (it's not that bad, neither one sounded that good anyway)
