How dry do the recordings for auralization need to be?

by A Buen

Critical listening to simulated sound fields in rooms and spaces can be done using auralizations. So, how dry do the recordings for auralizations need to be? We need to investigate this more closely, but we may draw some preliminary conclusions:

• The recording for auralizations needs to be drier than the room we want to investigate by a ‘fair amount’. We need to do tests to find more closely how much drier it needs to be.

• The level of the Schroeder curve needs to be lower than the IR for the room we want to investigate by at least 10dB (A hypothesis that needs further investigations)
