Death Star Groove AND mp3?

[taygan]

Check this one out. I'm guessing a very bad resmaple (from what??) and then probably mp3? The 16kHz line looks blocky, but not like most of the other mp3s I've been looking at. It's just plain ugly.

looks like 32kHz DAT > SB Live! imo

not too pretty, but I've seen worse! :lol

Haha, oh hell no.

Random 22.05kHz source with cutoff at 10kHz (maybe an mp3 already?) > crappy resampling to 44.1kHz > mp3 or similar lossy encoding

How the heck did that happen? Webcast maybe? I guess it sounds as ugly as it looks, too...

I disagree... what encoder settings give that kind of a SA signature?

is it possible to get a yousendit sample of this audio? 10-20 seconds? I'd like to hear if this has that lossy sslur to it.

mp3 sources normally have a signature like this (right?):

[taygan]

Yes, it does have a lot of sound artifacts, definitely a web-cast sound.

here's the sample:

I was wrong... this is lossy as f*ck. I can see it & hear it now.

Pretty much what I described... low bitrate encode of a 22050Hz mp3 may introduce a 10kHz lowpass for example; then mediocre resampling adds the "flipped" content above 11025Hz (and leaves the black hole between 10kHz and 12kHz); and finally another round of lossy perceptual encoding introduces the "skyline" around 16kHz.


PS: Five, I hope my "oh hell no" above didn't offend you in any way. I was actually referring to the SA of this track there, but upon rereading that post I noticed that it's very easy to misunderstand.

no harm :wave:

good eye!
