View Full Version : What is diginoise?

Hi folks,

Could someone point me to a site where diginoise is explained? Or if you have the time, a short rundown on its sources and how to detect/analyze (like you're explaining it to your slightly retarded cousin please). I'm running Linux, so the only analysis tools I've seen mentioned is audacity. My ears aren't that reliable after all those garage band years standing in front of the stack.

Thx.

it can be a static-y sound...or sometimes with DV, it can cause a high-pitched "robotic" effect to the audio...

So it sounds like bad vinyl or that "six-million-dollar man" (anybody remember Steve Austin :) ) type sound then?

I was reading in a DaD comment on a DVD rip about how diginoise was heard and then confirmed in a wave editor. Is the confirmation possible? Static and effects like echo don't seem to me to have a "signature" but then I still have to get grip on what frequency analysis is (intuitively I'd say it's a distribution of the signal into frequencies and their strength/intensities)

Thx for any answers/tips/comments.

You mean THIS SOUND? (http://www.leemajors.co.uk/Media/audio/BIONICFX.wav)

Ted: Yep. (hearing that is making me grin like an idiot) Thx.

I was going to come back and correct/edit the post. Thinking about it more, I think by "robotic sound" something like a dentist drill is what was intended, no?

willard - if you liked that one, go HERE (http://www.leemajors.co.uk/Docs/multi.htm) and roughly halfway through the page are more .wavs from The Six Million Dollar Man.

:lol = laughing (LOL)

No its okay Ted. It''d be good if someone could answer this though.

"I was reading in a DaD comment on a DVD rip about how diginoise was heard and then confirmed in a wave editor. Is the confirmation possible?

I mean, it'd be easy to explain that to an airhead, right ;>

I've met my share of electronic heroes. (Save me! Save me! ) lol

Gotta go to work now!

I think it'd be funny to have the star trek (original) door-opening sound as part of the desktop sound theme but It's probably been done somewhere .

Pot Head: It's cool. Just passing back the weirdness.

So I'm still stupid about diginoise. Why not just point me to a sample?

Diginoise and it's detection is part of a larger issue that interests me.
What I'd like to know in general is what and how commonly perceived sonic phenomena (such as diginoise but more so stuff like ambience) registers when it is analyzed. I think what people are doing with matrixing is interesting, to get a fuller sound from sbd and aud sources but is there anyway some instrument (of analysis) shows this? Is there even such a tool?

Maybe here's not the place to ask? If so, does anybody know where a forum for this kind of talk is? Hell, I can be stupid anywhere! :)

Thx.

I usually delete stuff full of diginoise but I've got a couple around somewhere. I'll post some screenshots and samples when I get the chance.

here we go...

here's a flac sample, attached screenshots are from this:

this is just one kind of diginoise. there are a few other typical kinds.

thanks Five...i'll try to dig some examples up and post some screens as well...

unfortunately, diginoise refers to a few different things...it can be glitches introduced in extraction, it can be caused by too hot of a signal on the source, amongst others...each can "sound" different, though each is definitely noticeable...

you also might find info re: diginoise, atleast pertaining to taping, over at taperssection.com

Okay, the diginoise (of this kind as with all others) is definitely obvious to the ear. So I guess that in the case where I read about someone using a wave editor to verify it, analysis was needed because it was at a lower volume.

Five: what are the screenshots of (ie. what type of analysis)? #1 and #2 are the same only with differing time scales. And what program did you use to do this? I tried playing around with audacity to reproduce something similar but it didn't work.

Anybody know of any good beginners guides to sound analysis (basic tools/kinds, scope, interpretation)? Or do I have to crack a DSP textbookto learn about this? :)

Thx.

The diginoise looks just wrong under close examination in a wav editor. the prog I'm using for FA is cooledit pro 2.1 aka adobe audition. The program for the FA is Audacity (select some music, go to view>plot spectrum and it gives the best FA). To see how to get a better SA with Audacity check here (http://www.thetradersden.org/forums/showthread.php?t=8706).

Yes, spectral screenshots are the same thing with different time scales. When you zoom in on SA to about 2 seconds lossy sources will show giveaway block shapes that aren't always visible when zoomed out.

Also just surf the lossy or lossless forum, it's the best way to learn.
