I'm trying to figure out how Pro Logic implements center channel extraction. Looking at how various different types of sine waves combine (a single one into two other ones), I guess I'll need to implement some type of FIR filter. I'm very new to this. It would be nice if this could be done on a sample-by-sample basis.
Any help? |

Since you want an in-depth explanation, you can have it.
This is really about Pro Logic II and the possibility of storing 5.0 music on a conventional CD. The only PL2 encoder I've really used is eac3to's, and it has horrible issues with crosstalk. I know of no good, standalone PL2 encoder that takes crosstalk into account. $800 for SurCode isn't ideal, either. I intend to change that. I also don't know what I'm doing, exactly. I have theories on how to eliminate crosstalk, but need to be able to dematrix the sound as a preprossing process. Pro Logic is merely a starting point. Does this make more sense now? |
