Decomposition of audio signals into primary and ambient components is useful for realizing spatial enhancements such as upmix and stereo widening. In this paper, we present several methods for primary-ambient decomposition of two-channel audio signals based on signal-space geometry. We discuss the performance of the various methods with respect to target… CONTINUE READING
