Hi,

I just made an experiment and calibrated dirac with only one measurement point for my 2 channel system. That turned out to be my best sounding calibration so far. Listening to hifi, there is pretty much only one sweet spot anyway, so kind of makes sense.

Anyone else tried? What is your experience?

I've done it but only below 200 Hz. This way it's roughly equivalent to the EQ I've manually applied in the past. Doing this is throwing away an important part of Dirac's intended capability though.

hi,

Are you sure? It should very well be possible to adjust in time domain based on only one measurement point, shouldn't it?

Absolutely certain but not in the way you're thinking. Dirac uses measurements over an area rather than a single point to attempt to distinguish between features that it's appropriate to 'correct' and features that it is not. It's not just about getting a smoother response over an area than at a point. If you Google the Dirac white paper you'll find a fairly technical document that describes this.

Applying Dirac to a single point measurement does still improve the impulse response. I have measured examples that demonstrate this.

If it sounds best to you with your current approach then do of course just use it and enjoy it :) .

After initial enthusiasm I have done some more testing. One point measurement work less well, in line with what you were saying. Thanks
