In this paper, we introduce a Downsample Upsample Shift Add (DUSA) method that faithfully implements the Time Compression Overlap-Add (TC-OLA) technique while overcoming some of the existing TC-OLA implementation shortcomings. The mathematical framework of DUSA relies on three operators: downsample, upsample, shift and add operators, and is shown to yield the same results as TC-OLA. Moreover, at some...
The application of a recently developed broadband beamformer to distinguish audio signals received from different directions is experimentally tested. The beamformer combines spatial and temporal subsampling using a nested array and multirate techniques which leads to the same region of support in the frequency domain for all subbands. This allows using the same beamformer for all subbands. The experimental...
