I’m mostly self taught, however, I am curious how to “trim” the realtime processing of my audio plugin. This is more of a Visual Studio/XCode question though. What is the best way to see the amount of resources my code is using.
I see people posting all over the forum, a bunch of benchwork test sheets of their code, I just don’t have a clue where and how to do that. I think it’s called a profiler?
On macOS there is Instruments, on Windows a small app called VerySleepy. Make sure you build the Release configuration with Debug symbols or you won‘t get too much information out of it.
A few tipps (they apply to both tools):
make sure you profile the audio thread and use a long enough measure time (about 20 seconds should be fine)
set the root to your plugins entry point
look for obvious hotspots by sorting by „exclusive“ (this means the time is actually spent in this method and not in a subcall)
then sort by inclusive and compare the usage to what you would expect.
