MD or MP3
Hello,
can someone tell me if following its from MD or mp3..Original source is probably a tape that was used for a broadcast...if there would be no blocks it could be a similiar encoding like http://www.thetradersden.org/forums/...ad.php?t=30357 Please explain detailly why u think that's it from mp3 or not..i wanna understand..;-) And: Can somebody explain what these thin vertical lines means that goes beyond 20 kHz? Thanx Uli No members have liked this post.

Re: MD or MP3
looks like MP3 at about 128kbps

Re: MD or MP3
ustone
clearly .mp3 because of the HUGE dropoff in frequency on the graph you provided at around 16kHz. This is the "classic" sign of there being .mp3 at some point in its ancestry. Also, the spectral looks "chopped" off at the same frequency, it's way too level, there should be more spikes than this if it were lossless. No members have liked this post.

Re: MD or MP3
I'd guess this is ATRAC3 (LP2) which is really a little worse than even mp3 128kbps CBR and should not be traded. The noise in the high frequencies demonstrates that it has been captured via analog but if it was mp3 it would be perfectly black up there. Don't trade this one. I was tempted not to post at all.
