Plug-in upsampling on bounce/freeze/export

If it sounds better, upsample it :)
 
My experience is that virtual instruments with lots of harmonics, amp sims with lots of distortion/high-gain settings, and dynamics processors with extremely fast rise times benefit the most. Here's a demo of the most dramatic example I could find about upsampling and waveforms with ultra-fast rise times.
 

 

afaik upsampling can result in a higher latency, that is if the tool you're using increases the latency at a higher sample rate.....for most of them it's hard to find out the latency they produce per sample rate, but Waves fe have this specified on the website.
Some plugins and (perhaps instrument too, I don't know) actually produce lower latency at higher sample rate.
And the CPU use usually increases with upsampling.
Other than those 2, don't know about any down sides to upsampling.

A big 'Yes' for up-sampling on render. The key is to check each plugin or vi to see if the performance is actually better.
Not all plugins benefit, sometimes the results can be worse so you really need to check. When they do you should a hear an improved sonic audio quality in your mixes.
 

It would be nice if Sonar included a "suggestion list" for common brands, like they auto-categorize many VSTs now. Tbh I can't be bothered A/Bing the 900-or-so plugs I use. Even if it takes just 2 minutes per plug (and it wouldn't) that's way more time than I'd want to spend.

Hi Dave,
If your upsampling doubles the latency of that tool, your music will be affected by it (in my opinion)...even if you have it set to offline render.
There is a 'latency compensation' in Sonar that uses the latency that the tool reports to Sonar and alligns all your tracks/busses so everything stays in sync / correct on the timeline.
In my opinion / my ears, this is not undoing/deleting the latency unfortunately, but it's just alligning it.
There are other opinions/ears out there...
 
Personally if I had a synth part that needed upsampling, and it's something like a stringpad, or simular...I would freeze that track.
That iic will bypass the Sonar latency compensation, and leave the latency just in that stringpad.
Again, this is just what I'd do, I don't claim any truth etc.
 
I thought the upsampling is another great thng we learned from Anderton sharing this with us.
Learned a lot from him and always like his posts/vids etc.
 
 
 
 
 
 

Latency has nothing to do with the sound of an individual track. It's impossible to "hear" latency in a track. If track alignment were off, this would be easy to check by rendering (which, by the way, is basically the same thing as freezing), but it's not the case. This has nothing to do with ears or opinion, it's easily verifiable. This is psychoacoustics at work.
