Shame on me, I installed the miniDSP SHD w/Dirac Live but havent gotten to using the built-in dirac live room calibration tool yet on the minidsp., what I've done so far, is try the Dirac room correction using Dirac for Studio on my Mac at the source.,before it hits the DSP/DAC.ĭirac Studio (part of their Pro audio tools now - separately licensed) gives me the flexibility to use any DAC and not tied to minidsp or NAD etc.,Looking at the screenshots, both seem to have the same capabilities(ie Dirac Studio on Computer vs bundled in minidsp or say NAD). So you shouldnt need to add additional PEQ filters. I'm still skeptical, unfortunately microphones simply do not discriminate the same way our ears do.ĭirac Live does mixed-phase room correction, a combination of IIR( PEQ & Crossover) & FIR filters.,correcting for both the amplitute(vs frequency) response as well the time domain response.

Iirc, Dirac is said to be a whole lot better than audyssey, and I believe it allows you to customize it a whole lot more. Secondly, a completely flat LF response sounds wrong and is not perceived as accurate, Harman's testing discovered that most people prefer a natural amount of room gain, (about a 6dB shelving at around 60hz), when testing various DRC software, ones that targeted a ruler flat LF response when normalized to the midrange and treble were rated as thin and bright sounding. Think of the xcurve, many have questioned its validity, and the same argument applied to target curves at higher frequencies above the rooms transition. The problems I have with most room correction software is that they try to address high frequencys above the room transition, based on a target curve that may or may not be appropriate in consideration with the room and speakers. IIR filters can only address phase and frequency simultaneously, while FIR filters are capable of independent adjustments.
