View Full Version : I've never seen this before.....lossy or not?

So I'm new at this whole SA/FA thing so maybe this isn't a big deal but I've never seen anything like it.

And while I've got your attention....what do you think about this one?

hey heather...can you zoom those in to around 2 secs? can't tell if thats a pilot tone or a mirroring affect...
the first one has a strange mirror effect and what I like to call "death star groove" up the middle. I've seen only a couple like that before. I ripped a vhs tape last year that looked like that, I was using creative sb live at that time, perhaps this is the culprit. as for what it is & how it happens ssamadhi97 explained it somewhere in this forum a while ago perhaps he will post here.
it is probably lossless, but I have to see more
the 2nd one looks totally okay from what I can see so far
2 second zooms as aar suggests would be helpful
I would also love to check a yousendit.com sample of the 1st track if you find the time (10-20 seconds or just a short track would be great)
and sorry to keep you waiting for your package I will mail it very very soon. I added a couple of bonus discs (melon) that you will love!

Erm. Yes. Sorry, forgot to reply.
Look for my brief explanation of "aliasing" in this thread:
Basically it's introduced whenever some kind of ghetto upsampling filter is used on audio material.
And by "ghetto" I mean something really dumb, like just duplicating samples as needed until there are enough for the desired sampling frequency (like for example EAC - or whatever performs resampling for it - does), instead of properly interpolating them.
just to clarify, you mean the EAC SA. EAC's read/write functions are flawless. thanks for finding that post, too!

Actually I was referring to resampling performed by EAC (for example when converting non-44.1kHz content to 44.1kHz).
But you're right, that doesn't happen anywhere near its digital audio extraction routines.
