AD1940 and ADL virtual surround
I have an application where I am using the ADL virtual surround module 5.1 to virtual setting . Anyhow, I am only driving the left and right surround inputs. During listening test when hard panning a signal left or right , the surround effect is better on the left side as compared to the right. Anyhow, I measured the frequency response of both channel when driving each channel separately and found that depending on the input driven, the resulting frequency responses of the channels is totally different. Now, I under that for surround effects to psychoacoustically work , the frequency response of two channels have to be different, but I thought that they would be symmetrical.
Does anyone from Analog Device have any additional information of this.
I may have been to close to the limit of the available instructions.
I reduced the number of instructions and recompiled and now it is symmetrical.
HI Richard:
Thanks for posting your own reply. We were about to start a long and tedious investigation on this subject. We'll still do some analysis but at least it's not urgent.
