Re: mm lossy?

well what is fairly easy to tell is lossy vs lossless sources. the steep cutoff in the fa and blocks visible in the zoomed in sa are the giveaways. pure black in the high frequencies of the sa is also an artifact of lossy encoding in the lineage.
I got that, but often the SA/FA aren't that clear-cut..

Quote:
when it comes to md it can be difficult to really tell the diff since it is lossy just like mp3 et al. the blocks often look a little more hyphen-like.
I think this show is more hyphen-like, but that is more based on my feeling, but then why is MD sourced okay to most traders. Isn't it as lossy as mp3?

I know Hi-MD's do support less compressed and uncompressed (?) PCM formats, but I assume you are talking about the older generation of MD's?

Quote:
it is possible sometimes that an md recording has also been converted to mp3 this is one of the most difficult things to spot.
that sucks..

your zoomed in sa is 2ms would be better if that was 2sec ( 0:02.000 in the view/length stat).
I see, must have been sleeping

If you want to upload a sample via yousendit.com post the link here and I can download it and have a look on my end.
I made 3 for you:

Freq's of the las one go up on the end & beginning of the sample (If you make an SA you will see what i mean), those are the spikes I was talking about.

One thing that is unfortunate about the show in question here is that it seems to have been recorded at a quite low quality setting and as a result the sound will be worse than the average mp3, which cuts off at 16kHz
True, the sound isn't great..

As I said microphone level set to high and show is distorted. I just don't know what to do with it.

Should I consider this as lossless format, but note that a mp3 recording of this show had been better (although the higher freq's would have been more smoothed out in FA?)
