AstoundSound Expander for Mac 3.0.1
The AstoundSound Expander is a software application that processes all audio on your Mac.
It takes stereo audio as input and produces a significantly wider stereo image, while preserving center information (e.g. vocals or center staged instruments), in real time. The result is a wider, fuller and richer listening experience that can be heard while playing music, movies or games. Hear it. Believe it.
