How to eliminate dialogue leakage in Lt-Rt Surround sound

[bimbla]

Surround sound

Lt-Rt gives surround but with dialogue leakage. We need some kind of variable gain control to eliminate dialogue leakage. Has anybody worked on this? Preferably I want suggestions using analog design.

Hi Bimbla..long time hearing from you,!!!!!!!!!!!!

give more details to me..Iam doing a HD filter) it is not the surround sound but infact it gives a rotating effect with a cross synchronisation on right and left speakers

Check the ST electronics website and i think old filemanager has some data sheets on virtual surround audio processors ..and some firmaware may be i can dig it out for you... :idea:

Thanks for the links! I will implement the same and get back with the results.
By the way, I have tested a circuit which does everything that SRS*technology promices us. I will upload the same shortly for people to evaluate it and use it.

Thanks again.
