Example
with a microphone array
§The
sound field is sampled in N points by means of a microphone array
Is the time-domain sampled
waveform of a wave with well defined spatial
characteristics, for
example:
• a spherical wave centered in a precise
emission point Psource
• a plane wave with a certain direction
• a spherical harmonic referred to a receiver
point Prec
