A 10 seconds sine sweep compressed into one tiny burst of sound. Feed it into your speaker when recording impulse responses of intresting rooms, halls, areas and spaces. Created with Voxengo Deconvolver.

Use Voxengo Deconvolver to generate a 3 - 6 second sine sweep from 20hz - 20khz. Play this through your device (or through a studio monitor in an acoustic space to be captured by a microphone) and record it. Load the original sine sweep file into Voxengo Deconvolver along with the recorded sine sweep. The program removes the sine sweep from the recording and time-aligns/compresses the file into an instant.
This method will produce a far better result!

The only option for me was to use a tool that could generate the deconvolved sweep automatic.

You don't want to use that to record impulse responses. First of all it seems like it's supposed to be a Dirac delta but it doesn't even sound like one.. And then what you want to do is record a sweep, THEN deconvolve it with the original sweep to obtain the frequency response. Because a sweep of several seconds has a lot more energy than a mere click, so you'll get less noise in your result.
