Abstract
Provided is an acoustic signal processing technique for performing a signal transformation suitable for desired signal processing (e.g., sound source enhancement processing) on a signal, and then performing the desired signal processing on the transformed signal. An acoustic signal processing device performs signal processing M which is a desired target on an input acoustic signal x. The acoustic signal processing device includes a transform unit that performs transform processing P on the acoustic signal x to obtain a first transform coefficient X; a signal processing unit that performs signal processing M corresponding to a desired target on the first transform coefficient X to obtain a second transform coefficient {circumflex over ( )}S; and an inverse transform unit that performs inverse transform processing Pon the second transform coefficient {circumflex over ( )}S to obtain an acoustic signal {circumflex over ( )}s subjected to signal processing which is a desired target, wherein the transform processing P, the inverse transform processing P, and the signal processing M are simultaneously optimized.
