Hi,

I am planning to use a Center channel to set a two seat Tune. Is a proper center channel processing possible in C-dsp 8x12 using DIRAC?

You would need an upmixer upstream 

then Dirac could set gains and delays and eq perfect for that channel 


you can do a L+R and sum them together to a si for channel , you just can’t extract L or R 

ypu can do a L-R for the rears however 

I would do a L+R on center , add rear processing and do about 10ms on rears after Dirac (not the 28ms) 

then when you take your measurements use the two seat algorithm in Dirac as directed 

then after Dirac adjust the output on center so the stage depth and imaging works properly 

that should do it 


I would definitely make a 1 seat configuration using the method I created and ANU on DIYma had made a how to page on , for when your driving by yourself (you’ll appreciate that tune a lot more) 

center channels have a difficult time imaging outside the car. 

i believe I posted that paper on here also somewhere

Here it is 

there’s two methods 

1 keeping the crossover phase shift in multi channel 

2 linear phase using multi channel (which is an appendix)
