Extraction of interchannel coherent component is a useful method that is applicable to the improvement of blurry sound image and setting up an upmix system. In this paper we propose a new method that extracts the component from three-dimensional (3D) multichannel audio signal. Such a signal sometimes has a negative cross correlation among channels because it includes independent sounds propagated from different directions. To handle this problem, a new method is proposed to estimate the component of one channel signal by the other channel signals having positive correlations with the signal in each subband. The experimental result showed that the estimation of the component by selected channel signals brought better performance than that by all channel signals.
