unkown source (bootleg) MD possibly?
All right y'all here's a source from a bootleg that looks strange, uneven flattened tops, but with spike through them. MD perhaps? opinions are welcome.

Re: unkown source (bootleg) MD possibly?
looks like MD source to me
analog transfer for sure also can notice some cd/cdr extraction errors

If you mean the vertical line stuff, that's more likely caused by clipping during transfer or saturation during recording No members have liked this post.

Re: unkown source (bootleg) MD possibly?
I noticed that the blocks themselves are almost U shaped, with a little tail extending up ant the start and finish of each one. is this typical of MD?

Re: unkown source (bootleg) MD possibly?
the MD signature when you zoom to 2 seconds tends to have that look like little parapets (is that the word?) built from lego (and a few free-floating blocks visible here and there). Take a look at some of the older threads in this forum, you can really get a feel for it that way.
transfers done digitally show pure black in the highs, whereas analog transfers will have that puple haze which is noise from the soundcard and/or analog output of the MD player. not so many MD decks even have a digital out (mine has only digital in but no digital out) so perfect digital MD transfers are a little more rare. EAC likes to show a haze on the highs on pretty much anything and everything, of course. Quote:

Re: unkown source (bootleg) MD possibly?
First of all, thanks, I'm really feeling better about analyzing these shows. Although it's annoying to reboot into windows to use CEP. I should try it with WINE.
ANYWAY, here's a different show (I'm trying to weed out lossy shows) but an interesting one. It may explain the spikes in the unknown manu bootleg. Well, after looking at the two, this one is a lot smoother, so maybe not. I don't understand the French completely but it's Radio (sat or FM?) recorded on an MD. Ah ha! The U-shape 'parapets', uneven blocks and then the occassional spike. (Sorry, I'm a little lazy with trimming the screenshots.) Here's the French text explaining the source. Five, you're Canadian, right? Parlez-vouz Francais? ++++++++++ Bonjour, Je viens de faire une image d'un CD qui comprend 23 chansons acoustiques de Manu Chao, enregistrées à la radio en novembre et décembre 2002. L'émission était captée par sat et enregistrée sur MD puis sur DD. J'ai scindé le tout grâce à CoolEdit (sans aucune transition audible entre les plages qui se suivaient) et recopié les .wav sur un CD. La qualité est impec. J'ai enlevé les interviews pour que tout tienne sur un CD (76 mn). Le fichier, qui comprend aussi les couvertures, est: Manu Chao acoustique by me.rar Les titres sont les suivants: -snip- No members have liked this post.

Re: unkown source (bootleg) MD possibly?
now this one looks more like its been mp3'ed unfortunately
it might be MD > mp3 at some point the cutoff is so straight and normally with md there aren't so many holes punched in the lower frequencies. I am 25% French and I comprehend about 25% of what I read... I do have a f-e dictionary handy I'll look up some of the difficult words tomorrow

Re: unkown source (bootleg) MD possibly?
I disagree, I don't see anything in that picture that particularly hints at mp3 compression. A couple holes can be perfectly normal for MD, too - in any case an MD encoder is the last lossy/perceptual encoding this recording went through.

Re: unkown source (bootleg) MD possibly?
looking more closely I think you guys are right, this is MD using one of the codecs that you don't see as often these days.
With a little head scratching, paraphrasing & a lot of babelfish I came up with this translation: Quote:
