I did a quickie video lasting 10min while I monitor the sound over the LCR I’m not focusing on the surrounds tonight that’s for another day.
I go though muting HF left and right and left and right and centre and given where the SPL db metre is placed it still missed the word “inexpensive” on the playback by a few db masking of left and right fronts. It’s getting near, its close to where it should be for clear reproduction.
SPL db was set at 70dbc so it slightly overloaded on the youtube recoding level at few moments. I should have set it at 80dbc.
Contrast and brightness levels wash the image out on the cheap webcam! The LCD video projector is picked up clearer on the webcam. You get what you pay for.
