Audyssey MultEQ room correction algorithm relies on the analysis of measurements in the time domain and the effects of sound reflections from walls and other room surfaces. In AVR systems, the filters are set to +9 dB max boost and +20 dB max cut. It uses Finite Impulse Response (FIR) filters. XT32 generates filters that have 32 times the resolution of XT for the satellites and 4 times for the subwoofer. I've gathered some facts and tips from my search and found, and will post some of them later.īelow is just to start, the list will grow for sure, the information under the heading MultEQ filters are mainly from the AH interview with the founder.

Actual FR graphs using REW/Umik-1 mic and/or Omni mic etc., are welcome, hope to see as many as possible. Emphasis is given on providing, sharing tips and even target curves. This thread is for MultEQ users in general, so it is not limited to Denon and Marantz product owners in case users of other brands may be interested in it enough to consider switching in their next purchase. There are a few such threads already, but no users/or owners thread that I am aware of, so I thought it may be better to have one for the users.
