About the adaptive beamforming technology
The adaptive beamforming technology is a technology where sounds from within the range of about 30 degrees in front
of this unit are recognized and captured as the target sound while unnecessary sounds from within a close range of the
target sound are significantly reduced at the same time.
Because the adaptive beamforming technology adapts the sound pickup pattern dynamically to changes in the
surrounding environment, unnecessary sounds are kept reduced even when their sources move. On the other hand,
environmental sounds at long range are moderately captured along with the target sound.
Ultra-directional mode (adaptive beamforming)
With
(Ultra-directional) selected by the directivity mode dial on this unit, the adaptive beamforming algorithm is applied
for recordings.
The following depicts how sounds are picked in Ultra-directional mode:
Subject/target sound
Unnecessary sound
Environmental sound
Other directivity modes
In any directivity mode other than Ultra-directional mode, the sound pickup pattern never changes dynamically. As a
result, unnecessary sounds from within a close range of the target sound may be captured depending on the location or
pointing direction of this unit.
For details about how sounds are picked in each directivity mode, see Selecting the directivity.
The following depicts how sounds are picked in Super-directional mode:
