Spatial analysis of room impulse responses captured with a 32-capsules microphone array

The new approach

130th AES Convention – London 13-16 May 2011

How can we obtain lots of directive microphones with only one probe? Using an array of capsules!

2009: first prototype of a spherical array (32 capsules)

Expanded polyurethane

(too much delicate for handling!)

32 capsules for earing-aid

(poor quality)


	A shotgun microphone comports a waste of time for covering all the directions on the hemisphere, changing more than one point of measure inside the theatre. For this reason we tried with a different approach employing a microphone array.
