Is exporting at a higher sample rate...

1. The same as if you changed your project setting to a higher sample rate, i.e. all individual tracks and plugins are rendered at that higher rate and will have less aliasing. Basically oversampling for your entire project.

OR

2. Is it just a normal mixdown at your projects sample rate to a final mix file, then a mostly pointless upsampling step done to that final mix?

................

I had assumed it was #1, and that I could use a low sample rate for mixing to lower cpu costs, and then mixdown at a really high sample rate which would make aliasing not a problem. But I can't seem to easily find an answer online.

Create a new project at eg 44 or 48 kHz sampling rate. Put a synth generating a 30kHz sine tone in your project (this is too high) and export at 96kHz (not too high anymore)
You could probably use MDA TestTone

but I'm not too sure this goes high enough.

If it's #1, then the rendered output contains that ultrasound. Otherwise it should be silence.

If plugins processing at higher SR by exporting then it's #1. Could be an advantage. But later you have to downsample from e.g. 192kHz to 48kHz. A delicate task? Could that be a problem? Even sonically?
