Ive heard a lot about the Apogee UV22 plugin for dithering, and know that this is included with Wavelab 5, which I own. When I dither, i usually do it in mastering. I'll load up the 24 Bit Wave, apply mastering effects, render, and then I will go to "save as" 16 bit wave file.
Is this dithering process using the UV22? If not, does it really matter?
Also in the UV22, ive noticed that there is a "noize type" that has to choosen to dither. I know by dithering, noize is inserted to replace the lost part of the audio file?, but why?
Also, what are the differnt types of noize in the plug in? 3 to choose from.
Cheers

May 23, 2005 07:22 am I also checked out on the help files with Wavelab and it explained there quite quickish style.
The dithering is indeed using the UV (there are 3 types) but I canny mind what each one is. If you check the online help with W/Lab, it does it in likesay 3 paragraphs which may be ideal for ye - tho Olddogs site he's passed is bloody good too, the online help may be shorter/snappier I thinks.
However, I think you will need to actually RENDER the dithering as the insert, with any others you are using i.e. maximiser etc THEN save it...
dB will pop in on that one for ya tho being a heavy w/l user.

May 23, 2005 11:15 am i've been interested in this one too...i'm usin' WL 4. i just picked one and went with it....i didn't know it was Apogee though! something i have noticed since, is that Sonar has an option to apply dithering upon bouncing to stereo audio...i havn't really bothered with either. gonna read up today!
May 23, 2005 11:25 am Sonar 4 also comes with a top-notch dithering tool cakewalk.com/Products/SONAR/precision.asp
Dithering is a difficult concept to explain...it's not just noise, but intelligent noise which is created based on the audio on either side of it.
I have always found it best to illustrate use a picture in photoshop. Increase the size of in image to about double and notice the "pixelation" of the image, jagged edges and all. That what happens as digital audio is processed, the computer is makes millions of calculations and generally drops remainders from the calculations. This creates a form of "pixelation" in the audio, jagged edges from places that were dropped off...
Just like photoshop dithering will make an empty pixel between a red pixel and a white pixel sort of a pinkish semi-transparent color to create the illusion of a smoother transition, audio dithering creates that sort of intelligent noise as filler in empty spaces...
I hope that makes sense, like I said, it's very hard for me to explain...it's one of those things I know in my head what it does, but can't really put it into words very well...
May 23, 2005 09:12 pm Mmmm k,
well im gonna hit wavelab when i get home, that help file. Cheers Coco
Ok, i get what your saying dB, but I still dont understand why there are three types, but i guess that Ozone website and wavelab will explain that for me.
Cheers guys

May 24, 2005 07:06 am Aye, wavelab explains the 3 types matey - its like UV22, UV22B? and something else. Each has its own characteristics and intended use I believe..canny remember tho!
Nae worries...
Cheers
Coco.
