Hi there
Is there anyone who tried that?
I just need a "simple" room correction and do not want to overcharge the PC.
Cheers from Switzerland

PS: Yes Sonnie, I'm the one from the Td10m-Beyma TPL build thread :cool:

I have not used it myself, but I have done several simulations with corresponding filter lengths. And it works pretty well.

But if you already have a PC in your system I recommend that you try that first. Two channels of correction is hardly noticeable on PCs from this millennium.

I did it. Still learning about the filters, but initial experiences are good. It improves stereo image a lot. Group delays and phase response corrected down to 30Hz.

Hi,
I personally use Acourate and AcourateDRC for generating the FIR-filters (combined with IIR-filters). If the filters are well created the import and functionality in the OpenDRC work like a charm. The correction by the FIR-filter alone is useful down to about 150Hz due to the 6144 tap limitation. The IIR-filters then should care about the corrections for the deep base.

Hi all
Thanks for the input. Meantime I'm stuck to rephase. I built a 3-way system with a Bliesma T34B-4, Scan-Speak 12 MU 4731T and a eton 11-212/C8/50 with a hypex FA123. The hypex does not support FIR so I do all corrections for the frequency response on it an use the OpenDRC-DI just for the phase correction. The result is amazing. The box sounds great without phase correction allreday, but then: More open, more precise (very defined voices or instruments) but close to too analytical, you can hear simply everything what went wrong on the recording :cool:

Well, I'll try Accurate too and will share the result.
Cheers
Werner
