MICROPHONE ARRAY PROCESSOR BASED ON SPATIAL ANALYSIS |
摘要 |
An array processing system improves the spatial selectivity by forming multiple steered beams and carrying out a spatial analysis of the acoustic scene. The analysis derives a time-frequency mask that, when applied to a reference look-direction beam (or other reference signal), enhances target sources and substantially improves rejection of interferers that are outside of the specified region. |
