*minidsp has their dirac live correction
, which is minidsp's proprietary time based/ magnitude based system. ie, it uses FIR and IIR filters to correct the response. you also have to have a umik to use it.
*minidsp ALSO has the boxes like the minidsp 2x4
,or the nanoavr
units, which have magnitude based correction, aka traditional parametric EQ.
*they also have the opendrc
boxes, which allow you to do FIR( time based ) correction. you have to measure the response using something like rew, use a convolver software like payware acourate, or freeware rephase
, or brutefir
to generate the filters, and finally load them to the opendrc box
* now,they have the minidsp 2x4 HD
, which offers both time and magnitude based correction
. to use the time based correction, you will use REW to measure the impulse, then use the convolver software of your choice to create the filters, then load those filters to the box. voila . a poor man's dirac.
except, this uses 2048 taps per channel vs dirac ddrc 88a 1200 taps per channel,(audyssey multeq xt32 has 512)
, and it does not require a umik, which saves money for those who have their own measurement mic.
here is how i see the typical avs member using it -if using it for room correction.
1.measure the room and impulse into REW room eq wizard(freeware)
2.on the PEQ side, use REW to generate and save the peq filters, which can be automatically downloaded to the 2x4hd
3. on the impulse side, export the REW impulse response to DRC(freeware)
4.use drc to create the filters,
5.export that to the 2x4hd,
here is a step by step using acourate as an example. keep in mind acourate costs money and there a freeware programs that do the same thing
