Cockos Incorporated Forums - View Single Post - 44.1k sample rate-still allow 75 kHz sounds?

I'm curious to know if individual plugins inserted in a 44.1 kHz project are capable of outputting frequencies that are as high as 80 kHz etc.

It is not easy to measure this directly. If I measure that individual track with a spectrum analyzer the project sample rate ( 44.1 kHz ) itself will not measure higher than to around 23 kHz.

SO my concern is that higher frequencies than alittle bit above 22.05 kHz are emotted from individual plugins without me knowing it directly. But that this HF "junk data" may affect other plugins and may of course also be a cause of aliasing distortion.

So How can I design a test that truly and withou doubt verifies if individual plugins are emitting above 23 kHz while sitting in a 44.1 kHz sample rate project?

That is my concern...
