APPARATUS AND METHOD FOR SPATIALLY SELECTIVE SOUND ACQUISITION BY ACOUSTIC TRIANGULATION
摘要:
An apparatus for capturing audio information from a target location includes first and second beamformers arranged in a recording environment and having first and second recording characteristics, respectively, and a signal generator. The first and second beamformers are configured for recording first and second beamformer audio signals, respectively, when they are directed towards the target location with respect to the first and second recording characteristics. The first and second beamformers are arranged such that first and second virtual straight lines, defined to pass through the first and second beamformers, respectively, and the target location, are not mutually parallel. The signal generator is configured to generate an audio output signal based on the first and second beamformer audio signals so that the audio output signal reflects relatively more audio information from the target location compared to the audio information from the target location in the first and second beamformer audio signals.
