Re: Output Dither
Dithering just works in the LSB and there is, with 24 fixed / 32 float, always noise.
That's the difference between 24 and 16bit fixed where dithering make sense.

Re: Output Dither
Anybody who can show me they can hear any difference from any dithering at anything near 24 bits I'll buy them a case of the finest America Budweiser.

Re: Output Dither
Those are all valid points, but I understand this place as the support forum for Pro Tools and didn't came here to get lectured if one should dither or not (there is a discussion over at gearslutz). I simply wanted to know if Pro Tools does this, yes or no. I thought it did, because I misinterpreted the quoted sections of the manual, and came here for clarification. I was wrong and will dither the outputs myself from now on, you don't have to and we can discuss all this over at gearslutz. No disrespect, I was simply seeking for a technical answer from my DAW manufacturer.

Re: Output Dither
I don't know if PT is dithering from 64float to 24fixed but what I know is, that it doesn't make any sense to dither after the physical output.
It needs to be dithered in the 64float to 24fixed conversion process. If it is already 24bit PCM you're just adding noise without any further advantages.

You do NOT need to have a dither plugin on your output UNLESS you're planning to bounce that output to a smaller than 24bits size file. PT does NOT "dither the outputs", because it's not necessary. Your interface recieves a stream of 24bit samples and converts them to an analog current, D-A. Quote:
NO, PT does not do this. |

Re: Output Dither
... which is why it is DAW mixer responsibility. Any dithering plugin has zero effect on or after physical output.

Re: Output Dither
Because the output of dither plugin goes to 64bit mixer that feeds the physical output

Re: Output Dither
Conversion from floating-point to fixed-point is different than fixed to fixed. Which is why you should not worry too much about it. You can think of it (overly simplified) that when you create a fixed-point word from floating-point you get 23 solid bits and the last bit is calculated from the floating point mantissa. So in a sense it is dither in itself. Whatever "errors" there may be are about -140dBFS

Re: Output Dither
Speaking of Dither, It would be great if we could choose what dither algo to use on "Exporting" files. Goodhrtz,Izotope etc....
As of now if exporting 24 to 16 the stock dither is automatically applied. In my workflow, I use print tracks and export clips as files. If I want to export say 96K/32 mixes or other clips, and use a better dither, I have to do that out of protools. A drop down menu "Dither" should be in the export selected box. you would figure that would of been implemented by this point......
