Mp3 or noise reduction?

Again I'm not sure about a show. This is a very good audience recording from 1981 recently released as a pressed bootleg. If I had got this without any source info I wouldn't trade it, but now I'm wondering if they used a mp3 source for the bootleg or if this is the result of a noise/hiss reduction attempt maybe.

Thanks in advance for your help.

Re: Mp3 or noise reduction?

this is MD

there's a bunch of old shows going around which have been thru an MD lossy encoding stage for some reason. MD is only considered tradeable if it was taped that way at the show. since this is from 1981, that obviously isn't the case.

hopefully a better source will show up

Thanks. It's just strange, because this show has never circulated among traders until the bootleg came out 1 or 2 two years ago, that's why I found it hard to believe that it went through any lossy encoding before, I thought the bootleggers took it from a tape. Anyway I won't trade it then.

Re: Mp3 or noise reduction?

Just by looking at these pics I'm not so sure that it's MD and not MP3, but seeing how it's a show from '81 this is irrelevant anyway.

That aside, it has been observed that many recent bootleg pressings are mastered from MD or even MP3 sources - whatever the bootleggers can get their hands on is good enough for them, I guess.

yeah, some of the companies' standards have really dropped lately. I think this looks like ATRAC, btw. ATRAC2 and newer cut around 18kHz.

Re: Mp3 or noise reduction?

Yep, I tend to agree, especially because of the uneven cutoff.

Ahh, I'm so out of training.
