I am about to purchase the Acoustisoft's ETF software but I noticed that they sell some extra add on modules that I can't decide if I need:
This appears to be for loudspeakers, which I probably won't need for a while unless I design my own monitors, right?
They are normally $75 each but if you get all 3 at the same time with the purchase of ETF then you basically get one free (+$150).
Would a beginner (with ambitious acoustic design hopes!) benefit by any or all of these add ons? Also, any opinions on Fuzzmeasure Pro ? I tend to prefer Mac software but everyone in acoustics and loudspeaker design seems to use ETF so it seems wiser to go that way for now.
Thanks!
PSD / Sweep
The PSD / Sweep add on provides the user with the low frequency room measurement power to see the room response in terms of individual room modes rather than an approximation, such as found in other analyzers.
Psyco Acoustic Response
It has long been known by professional sound installers that setting frequency response with an EQ and RTA results in a system that does not sound correct to the trained or experienced ear. The reason for this is that human ears work differently than spectrum analyzers. Adjusting a system for perfection as measured on a spectrum analyzer does not result in a system that sounds "flat", as it should This gives the user an unprecedented resolution in diagnosing room problems as well as evaluating the effectiveness of room treatment or modification for a specific resonant frequency. This is acheived by using a sweep test signal that shapes itself to the particular background noise in the given environment. ETF provides a psychological model of the human hearing system that more closely approximates what is actually heard, giving inexperienced listeners the capability of measuring their systems more accurately. It gives professional users speed and precision in making these adjustments.
