Conclusions
• A new spherical
microphone array provides robust hardware platform for capturing spatial
information
• HOA processing of
the signals is possible for synthesizing virtual microphones with directivity patterns up to 3rd order
• A novel
processing method has been developed, not relying anymore on spherical harmonics, capable of
providing sharper virtual
microphones, up to 6th order –
equivalent
• An advanced GUI
with realtime 360° video background has been developed for aiming correctly up to 7
virtual microphones
during live broadcasting or in post-productions
• The first
operational tests confirm that operation is smooth and reliable, and the quality of the signal
provided by these virtual
microphones is comparable or better than state-of-the-art shotgun mikes
