The DSP Dimension has announced the release of DiracFxAU, a free pitch shifting plug-in for the Apple AudioUnit platform based on its new DiracFx API.
DiracFx is a high performance pitch shifting and time stretching algorithm that allows changing pitch and speed of audio signals independently of each other at very high quality and very fast speed. Optimized for use on mobile platforms, DiracFx uses no trigonometric operations and is available for iOS, Mac OS X, Windows and Linux. A feature-limited DiracLE edition of the SDK is available to developers at dirac.dspdimension.com (this distro also contains the AU plug-in), a professional version can be licensed from The DSP Dimension upon request.
DSP Dimension is the former Prosoniq R&D department and the company responsible for developing the DSP technology behind all Prosoniq products.
