Re: [Audacity-devel] R: Re: Modules & grids....

SourceForge Headquarters 1320 Columbia Street Suite 310 San Diego, CA 92101 +1 (858) 422-6466

This is just the first module of a complete suite, do not expect to get full
functionality from it alone... For measuring impulse responses with the MLS
or Exponential Sine Sweep method, other plugins will be required: those for
generating the test signal (genMLS, genSweep) and those for extracting the
impulse response from the re-recorded signal (DecoMLS, Convolv, IRselect).
Currenty the only usage of the Acoustical Parameters plugin is with
already-measured impulse responses. The easy way for getting them is
employing exploding ballons, or firing with a blank-shot pistol, and record
the room response....
Although electroacustic methods have some advantages, these old "pulsive"
methods are still quite viable, and usually perform very well in a silent
enviroment. Even this evening I did measurements with balloons...

If you want more infos on impulse response measurements, have a look at the
following presentation:

http://pcfarina.eng.unipr.it/Public/Presentations/AudioPrecision-workshop.pd
f

And if you want to read a detailed explanation about the Aurora plugins, you
are referred to the Aurora web site (www.aurora-plugins.it), where you can
find the manual, a number of web pages explaining what each plugin does, and
a long list of scientific papers, all downloadable in PDF format.

Bye!
