Dither checkbox greyed out


jeffythedragonslayer

Question

I've noticed that in the Change Audio Format window, the Dither checkbox becomes greyed out when the New Bit Depth is set to 32 or 64.

However, I can simply set the bit-depth to 16 or 24, toggle the checkbox, and then change it back to 32 or 64 as a workaround.

What is the purpose of greying out the Dither checkbox when it is so easy to bypass?  Does anyone ever use dither when converting to a higher bit-depth?

Tried to tell them that but they didn’t seem to believe me. 
 

Cakewalk works with 32 bit by default. So if you choose 32 bit why would you want dithering ?  And if you choose 64 why would you need dithering?  If you reduce to 24 or 16 then you might want to dither. personal choice. 
 

It might help if you take a few minutes to look up what dithering is for then you might understand why our answers are as such.

Well you can add me to the list of people who believe you 😄

Ok.  I'm not saying I want this - I'm just curious about why the UI works this way and whether anyone has exploited it.

I don't see why I would at 64.  But maybe someone else would want to in order to create some cool effect unknown to me.

I understand everything written here except for scook's message (see below.)  I'm just confused about why the UI works the way it does (it looks like a bug to me) and if anyone has found a use case for dithering when going in the opposite direction.

The DAW will not dither in this case.

Dithering is only possible when bit depth is reduced.

So this is a Cakewalk limitation.  (I suppose someone can add noise to a signal with low bit depth being converted to high bit depth if they want, but if my understanding is correct here that wouldn't typically be called "dithering."  I might just call it upsampling followed by adding noise.)
