My sole input device in Windows is a microphone. I have deactived What-You-Hear.
In Cubase, I arm an audio channel, and I press record.
On my microphone, I have an Off switch.
I physically disable / mute the microphone using the Off switch.
In fact, no sound should be recorded now as there is no input on the microphone.
However, the recorded audio does record VST instruments, not loud, but clearly audible.
This is an example of such an audio file: https://drive.google.com/file/d/1tOF8RRAulaTYWIGIYGlJopHyP27fIg2I/view?usp=sharing
In this audio file you can hear little bits of the drum VST that I’m using in this song.
Also, what you hear in this sample is not just low in volume, it sounds like digital artifacts or so.
When I record anything in Wavelab, these artifacts are not to be heard.
I’m baffled why this is happening.
I would say that I’m really experienced with recording, so this really confuses me.
What could I check?
ps: I’m using Creative SBZ Series ASIO
