DSP Dimension Releases Dirac 3.5 – Introduces DiracFx API

Mainz, Germany, September 13th, 2011 – The DSP Dimension today announces the immediate availability of version 3.5 of its award winning cross-platform time stretching and pitch shifting library DIRAC. Version 3.5 is a free update for licensed users and adds new features to the Dirac core and the DiracRetune API, such as key mapping and automation callbacks. It also introduces “DiracFx”, a new API that offers transient-aware time stretching and pitch shifting for polyphonic music at unprecedented speed and unbelievable quality. DiracFx is the world’s first time stretching algorithm that does its DSP magic without using trigonometric functions, resulting in dramatically increased performance over traditional FFT based methods.

The free DiracLE library has also been updated and now contains a free DiracFx AudioUnit pitch shifting plug-in for MacOS X 10.5 and higher (32 and 64bit Universal), that can be used with all AudioUnit aware host applications on any MacOS X system. Plenty of example projects for Linux, MacOS X, iOS and Windows are included with DiracLE, which can be downloaded for free from http://dirac.dspdimension.com
