This directory contains the results of polar pattern mesurements
(based on impulse responses) made at the Anechoic chamber
of the University of Ferrara on days 28-29 July 2008
Over 5 microphonic arrays
- Brahma
- Soundfield ST250 PR
- Tetramic FE
- ZoomH2 internal mikes
- DPA4 PR
- Holophone
The polar patterns are charted inside Excel worksheets, in octave bands.
For each microphone the original set of impulse responses coming from
the capsules is saved in a 4-channels WAV file (for the Holophone, 
8 mono WAV files are saved).
Furthermore, for the Brahma (the only one for which we have a set of working
inverse filters), it is available also the set of A2B filters, the convolution
VST plugin (Xvolver), the set of B-format (processed) impulse responses,
and another Excel file containing the B-format polar patterns.
