TOPIC: DDRC-88A-BM speaker delay compensation

I previously requested a on/off for speaker delay compensation as this delay imparts very audible comb filtering in a well treated room and havent gotten a response in weeks so ill try this another way.

Since you are obviously unwilling to add this functionality into the software/firmware i wonder if it would be possible instead to simply overwrite the parameter after dirac creates it.

After measurement, dirac saves all generated files to the computer for backup. Would it be possible to open the filter settings file in a text editor and then change any delay value imposed by the software to "0", and then save the file. And load the new edited version in my ddrc-88a?

You can add delay on the output channels.

I dont want any delay. I want to turn the speaker delay compensation off. Adding delay to all channels will just add latency

Um, Dirac Live inherently has a delay. If your left/right delays are off by more than a few percent of the delay it already has, there is some issue you should get to the root cause of.

If the measurement mic isnt perfectly centered youre going to cause delay compensation thats not really needed. In a heavily treated room this delay causes very audible comb filtering, especially when monitoring in mono. Dirac knows this and you can turn off speaker delay compensation in the computer version. This feature didnt make it into the minidsp version for whatever reason. I just want to turn it off in the minidsp version. I realise using dsp adds latency, so does my asio drivers. Im trying to keep it at a minimum.

If you're mixing to mono, you will need to have that "before" Dirac Live in the signal chain, not "after".

I dont want to send a mono signal to dirac. I want to check my mixes in mono for phase cancellations. And even more than that, even a stereo signal still has much of the energy and content panned right down the middle which can still be problematic when one channel is delayed. I will be using dirac to help do the final smoothing of the frequency response and decay times in my highly treated studio control room. Monitors are flush mounted and their relation to listening position has been laid out very carefully and early reflections will be supressed effectively.

Of course, you can do what you want, it's your gear. However, if you mix to mono after the Dirac Live correction then the left speaker will have the correction for both speakers applied to it, and vice versa. This is regardless of the delay setting. Most people would consider this suboptimal I think. Possibly counterproductive, if the point is to "check your mix for phase cancellations."

Im not sure i follow you. Im not routing the output of dirac to mono, ie sending one output channel to both speakers. Im sending a mono signal from my daw through the chain. Instead of having wide panning and different sounds on left and right channels the stereo signal will be summed to mono. Everything panned dead center, both channels playing the same signal. Each speaker is still independent, they just play the exact same thing. Because of this, the delay dirac imposes causes comb filtering and phase cancellations because of the time difference in the two copies of the same signal.
