DIRECTIONAL AUDIO SIGNAL PROCESSING USING AN OVERSAMPLED FILTERBANK

摘要

A dirctional signal processing system for beamforming information signals. The system includes an oversampled filterbank, which has an analysis filterbank for transforming the information signals in time domain into channel signals in transform domain, a synthesis filterbank and a signal processor. The signal processor processes the outputs of the analysis filterbank for beamforming the information signals. The synthesis filterbank transforms the outputs of the signal processorto a single information signal in time domain.
