Center channel from stereo. Will this work?

[diwakarma]

Hello, Greetings!

I am just trying to develop a stereo to 5.1 conversion circuit. So far, all are working fine. For center channel from stereo, the easiest way is to combine both left and right channel with resistors and feed to op amp.

I just tried it differently, to get the center channel as shown in the image. I am using TL074 and 15V dual power supply.

So far everything works fine, but I just wanted to get expert advice, to check if this is a bad design.

Thanks in advance!

IMO it is better to substract both stereo chanels over add them.
