3 minidsp 2x4hd and a OpenDrc

[Andrew Slater]

As title says I have 12ch of fir and 12x10ch of iir and a 2ch of upstream fir

12ch are 1024 samples at 96k
And upstream open is 3100 samples at 96k also (can be made to do 6100 samples at 48k)

my question is

Will audiolense be able to make a correction and put all 13 channels of fir into its system and be able to divide the delay taps how I want them to be made and output an fir for each device and respective channel.

i am hoping to build a correction that is all exclusive on the same set of measurements for each driver and have each correction for each channel compliment eachother

i want to do driver tuning and linear crossovers in the outputs and a global room and sum correction with the OpenDrc and have all channels and stuff be managed in audiolense and done all start to finish….

ive been using rephase for crossovers now and the iir channels on the outputs for driver tuning and using a Dirac ddrc22 for the summed correction…. I want to do it all manually and do it all together in one interface and not have to bounce between REW, Rephase , Dirac …..

I also want to adjust everything together for making and trying different things without having to start completely over like new measurements and stuff

will this do what I want ?

thanks in advance

And it would even better if it can separate the fir and iir segments and give me biquads to import as well

I doubt that this will be a good solution. Too small fir capacity, but you can find out with the demo.

The bottleneck will be 1024 coefficients for the lowest XO. You can e.g. try with the enclosed 3 way stereo measurement, where you can play with different crossover settings. Just remember to specify 1024 fir length in the correction procedure.
6000 fir coefficients is usually sufficient at 48kHz for a global correction, but it depends on what you try to do.

Audiolense only used fir btw.

Thank you!
And maybe that’s what I was sorta asking

so I can allocate 4069 taps over 4 ch
So I can actually squeak a little more if I use one dsp for sub and tweet , like a 200tap for tweet and 1996tap for sub

regardless, I have been able to make a 1200 tap filter work with rectangular windows, and an impulse centered at 10ms, at 80hz….

will I be able to set impulse centering and windowing? So I can archive good attenuation at LF with less taps?

And if so, otherwise, would audiolense do everything else I asked?

can I measure work the correction for each speaker, measure again and do the main target in the sum with this all in one screen and see every speaker and have them all compliment eachother?

Audiolense operates with fixed length fir filters. Same length for all drivers.

I’m afraid I sm not able to go into further detail here.

 

[Andrew Slater]

No problem…. So maybe the 2.0 version for the OpenDrc. I’ll do everything else manually in rephase

Or…… I’ll stack a bunch of OpenDrcs

If I email you can you help further please…..
the software looks very exciting and promising

You need xo if you want the time domain correction. The frequency correction does a very good job on its own, though.
