How to implement this EQ block in miniDSP?

[wonderfulaudio]

Hi,

Please find attached the block diagram of Equalization I would like to implement in miniDSP. I have 2 way plugin with me. Is it possible to do it in miniDSP at all, if yes then using which plugin?

Thanks and Regards,
WA

No, I'm afraid not. 'Not with the typical scheme the older miniDSP software utilizes.

I wonder about your approach though. The top "adder" just sums and creates an all-pass response. Is that your intention?
Also, I'm not sure why a 10mS relative delay would be needed in most situations.

You can't. There is no "adder" (non-inverting summer) in the miniDSP routing that can be configured that way.

Not that this is the same as my particular reason, but after finding I could not do certain things under the miniDSP routing and filtering options I moved on to computer based DSP.

Hi Dave,

Thanks for the quick response. Yes the adder is intentional, it is done to get phase right with the other output.
10ms is not an actual delay. I have not calculated what the delay should be. I am trying to implement a cardioid with this block and the two outputs are front and rear drivers.

Warm Regards,

Thanks Charlie, I will try to do it with op-amps now

Problem with op-amp based implementation is that delay cannot be implemented.

Can I do it with Analog Devices Sigma Studio? Does it work with miniDSP since it uses ADAU1701 that can be configured by Sigma Studio?
