I can understand where he is coming from with the two separate sounds entering the same microphone one would expect them to be equally affected, if any affect is present, of course.
I would at least expect to have the recording hardware tested for consistency and have this stated and verified. This would need to be stated in the protocol.
Daylightstar, please guide me on how to do that zip file upload.
I create a zip file and add the recording to it? If so, how do I attach it?
sorry, can't help it.
