论文摘要

本文介绍了SMP-PHAT,它通过合并在空间中平行的麦克风对来执行声音估计的到达方向(DOA)。这种方法减少了成对的互相关计算的数量,并在搜索DOA时会带来拖鞋和内存查找的数量。使用常用麦克风阵列的低成本硬件实验表明,所提出的方法提供了与以前的SRP-PHAT方法相同的准确性,同时在某些情况下将计算负载降低了39%。

This paper introduces SMP-PHAT, which performs direction of arrival (DoA) of sound estimation with a microphone array by merging pairs of microphones that are parallel in space. This approach reduces the number of pairwise cross-correlation computations, and brings down the number of flops and memory lookups when searching for DoA. Experiments on low-cost hardware with commonly used microphone arrays show that the proposed method provides the same accuracy as the former SRP-PHAT approach, while reducing the computational load by 39% in some cases.
