I posted this at the cubase forum too but here is is in case someone here can tell me. What is the UV22HR plugin really for. It opens in the place you'd open plug ins but what the heck is it? I mean I know it is suppose to dither but how do you use it, do you use it even? Is it just there and if is so great, why would it be a plug in and not just port of the export? Anyway, any light on the subject would be more then I understand now

It will add a certain amount of random bit toggling to the LSB, a bit like extremely low level tape hiss. Here's an artical about it: http://www.harmony-central.com/articles/tips/dithering/

In this case: Let's say cubase works with a 16bit internal depth. It means that each sample can have 65 536 different values, from the quietest to the loudest. Ths is 65536 levels of loudness. Now , you want to export you music to a 8bit mixdown. It means that you'll have not 65 536 different levels available, but only 256. So now, let's take one sample. It's original value is 50 000 (on a scale of 65536). Going to 8bit will reduce the scale to 256. Your sample should then take the value of 50 000/256=195.3125 But there is no such thing as a decimal value in our case. So, if you don't apply Dithering, your sample will sound "195". The same error will be made with each sample, ending in a noise, aka information that doesnot correspond to any recorded sound. But if you use very high frequencies (not audible) to each samples, you can round up the division result with the noise *you* chose, and not the one that is generated by the abrupt division. For instance, UV22HR will say: Ok, we have a sample that's worth 50 000. I chose to add very high pitched noises to this sample so that it's value reaches 50 176. The noise I added will not be earable since it will be quiet and high pitched. When comes the time to export to 8 bits, the division will be: 50 176/256=196 The result is an integer, meaning that You'll get exactly the same sound in 8bit than the sound you had in 16bit with the dithering sound added. There. Huey PS: of course, Cubase works in 32bit internal, not 16bit, but you get the picture.

In normal use, you'd put it in slot 7 or 8 of your master bus. When mixing down for CD, choose normal and 16 as the bit resolution. HTH, CS

You should have written that article. It was good but you said it better - Thanks

I just did a mixdown and now I guess I'm going to do it again because I CAN here that nasty tail end noise. thank you too for that - I feel like a new man - all smart and stuff

Not that it changes anyhting, but I mistyped here. One should read: --Your sample should then take the value of 50 000/65536*256= 195.3125-- But you'd got the point, anyway... Huey

That changes everything - no wonder my mix came out so messed up I used it for the first (and second) time yesterday. I don't know that I can really hear much difference or not. Its subtle at best but since I did some other things to my re-mixed mix down I cant really tell the effect it really is having but I am going to trust the younger ears on this. Mine have suffered snare-drum syndrome for about 36 years so some things might get past me. Appreciate your help -

You could hear the difference in a very quiet passage that you would normalize. If you want to hear exaclty what it does, you can also make a bounce to a 8bit file with and without dithering. You can't miss the difference with this trick. Without dithering, this is Atari 2600 land, and with it is ... quite similar to the 16bit file if you are listening from your car cd player... have fun.
