Is there a point for me to even bother? I got a cheap checkmate cm-130 SPL, it really helped with balancing especial the sub & back speakers. I am learning more& more about treatments & traps. It's the math & practical meaning of terms that is throwing me. Basic concepts:Where and how to find 1st reflection pnts?
I am looking for a tutorial that not only shows me how to use wizrd, but how to apply it to room acoustics and speaker placements. A lot is taken for granted for knowledge. Which is fine, it looks like a good program but take a look below, the intial description of wizard and this symbol ?
of what I dont understand:
Room EQ Wizard is a Java application for measuring and correcting room resonances. It includes tools for generating test signals, measuring SPL and frequency responses and automatically adjusting the settings of parametric equalisers ?
to cancel the effects of room modes ?
. It was initially written to help with the setup of the parametric TMREQ filters ?
on TAG McLaren Audio AV32RDP and AV192R ?
, but the latest version also supports the BFD Pro parametric filters?
(with correct modelling of the effect of the bandwidth control?
, which is quite different to the description in the BFD manual?
Measurement is stepped sine?
, with local loopback?
for soundcard response compensation and DFT ?
to isolate the measurement frequency. Log swept sine measurement?
and impulse response extraction ?
are on the dev list but some way off. The Wizard can also import measurements in the ETF export formats?
or from text files in a basic comma-delimited format - details are in the help files, which can be browsed online at the site and are included in the program.
The sig gen?
provides sine waves to 0.1Hz precision?
, sine sweeps (linear and logarithmic)?
, square waves and various pink noise signals including "full" range (pink spectrum down to just below 10Hz?
), speaker cal?
, sub cal ?
and custom filtered?
to suit your needs?
Note that the app requires V5.0 or later of Sun's Java Runtime Environment (JRE) to be installed, available from http://java.sun.com/j2se/downloads.html
Hope it proves useful.
