[Rwp] rendering again

[Justin Macleod]

Hi, 

 

I’m slightly confused. 

 

You said: 

 

so considering our plug-ins generally process at 32 or 64 bit
if we render out at 24 bit and then brin the file back in for further use, then we theoretically might be throwing away some resolution.

But why would we do that? If you needed the file again, why would you not just open the project with it in and copy the audio across? Then you would have the 64-bit version. I totally see the need when gluing items and freezing tracks, but rendering out everything at 64 bit float when you have the projects anyway strikes me as being exceedingly hard-drive space intensive. 

 

Plus, how is using 24-bit files that you’ve have rendered out from previous projects any different from a DJ mixing with 16-bit CD tracks for mix tapes or film production houses using 24-bit sound effects and royalty free music. If you use any third-party media at all in your projects, from sample libraries etc, you’re going to be taking the same quality hit as compared to a 64 bit version of the same file. 

 

Sorry if I’m being dense and have missed something, 

 

Justin

HELLO Chris

out of subject question

i wonder are you a blind person?

or a sighted person helping here?

Been reading the manual and playing with reapers different options for rendering and bit depth and dithering and such.


I noticed, when you consolidate or export tracks,
there is no option for dither there.

When you render to a bigger bit depth than you are recording,
the extra bits are padded with zeros theoretically, but when you go the other way, you want something to fix up those rounding errors, or ragged tails you might have on the ends.
way down low.

You'd never hear it probably with any modern mix hugging the top end of the scale, but sonar has dithering options all through the architecture,
you can set dither for triangular or rectangular, or pow r 3, or turn it off is you want, but the only place I find it in reaper is a single noise shaping option and dither option for rendering.

so because of that reason, I wonder if maybe best practice in reaper is to set everything the same across the board the same until you are going to do your final render.

In other words, since reaper defaults to 64 bit mixing resolution
then maybe we should render to 64 bit floating point.
Sonar's rendering is set to 32 floating point by default,
and there is a check box to check and uncheck the 64 bit double precission processing engine, which probably equates to reapers 64 bit internal mixing depth,
so considering our plug-ins generally process at 32 or 64 bit
if we render out at 24 bit and then brin the file back in for further use, then we theoretically might be throwing away some resolution.

But leaving everything at 32 or 64 bit, and leaving any shaving down of the file till the very last would guarantee never to introduce rounding errors to the process.
The way it is now, if we ever need to use the consolidate options or the batch file processing, and we choose a lower bit rate, than what the files are in at present, then
I seriously wonder if reaper does just truncate those extra bits.
Also I wonder even when dithering down when we use the render option which does give us that single dither and noise shaping options,
even when we are rendering to 24 bit, if we are coming from a 32 or 64 bit environment,
if we should go ahead and turn on dither.
Reaper also has some interesting features that you can't do in sonar, like reducing the mixing latency down to even 8 bits if you like.

And some things I've never seen like 39 bit and 12 bit.

Which makes me think that maybe if you want to do straight recording, and never dither at all, for something casual, where processing has already been applied,
oh, for instance a radio show marathon that went on for a weekend, and you wanted to just go off and leave it and then come back and if you didn't do any volume changes, or any processes inside reaper involving plugs, or gain staging and such, since technically with a DAW, or you don't change a fader anywhere then what you put in should be the same as what you get out,
then I wonder if lowering the mixing resolution down to the file format you want, say 16 bit or 24 bit, I wonder if that makes any sense?
