Releasing DIRAC2 Version 2.1 With Pitch Correction
November 9th, 2009 — The DSP Dimension is happy to announce version 2.1 of DIRAC. Version 2.1 is available for download as of today and fixes several bugs that could affect performance and precision. Most importantly, polyphonic formant correction could produce unpredictable results with previous versions and pitch shifting could sometimes affect the length of the processed audio. All these bugs are fixed in version 2.1 and due to popular demand we have upgraded and re-enabled pitch correction in the latest version. DIRAC LE on all platforms offers pitch correction on a equitempered scale while the PRO version adds support for arbitrary tuning tables and direct pitch manipulation. Please see the README file that comes with DIRAC and the DIRAC product page for more information.
The DSP Dimension Releases DIRAC2 on Windows, MacOS X, Linux and iPhone
Mainz, Germany, October 23rd, 2009 — The DSP Dimension is proud to announce the release of version 2 of its much anticipated DIRAC2 Time Stretching and Pitch Shifting object library now available for Windows, MacOS X, Linux and the Apple iPhone. DIRAC2 is available as both a commercial object library offering unlimited sample rates and phase locked multichannel support and as a free single channel, 44.1/48kHz LE version.
Our free DIRAC2 LE project offers the full audio quality of the commercial version, is fully documented and easy to understand, and compiles and works right out of the box. Think of the potential that you can unleash in your app (and the added value) by writing just half a page worth of additional code without even investing a single dollar.
About DIRAC2
DIRAC2 redefines the limits of what todays’ technology can do for your application if you want to change the speed and pitch of music independently without sacrificing quality. Used by leading hi-end audio processing applications and custom built solutions in studios around the world, DIRAC2 is the improved successor to our critically acclaimed DIRAC time stretching and pitch shifting technology that works with both musically monophonic and polyphonic signals with equal ease and success. Its straightforward API makes this an ideal tool for any software project that requires time stretching and pitch shifting.
From Creativity to Hi-End Mastering
DIRAC2 can be used wherever speed and pitch of audio need to be changed independently of each other: for NTSC/PAL frame rate conversion, for adjusting the length of an ad to fit into a predefined time frame, for changing speed and pitch of audio tracks for remixing. It does all these tasks without making your music sound unnatural or altering the stereo image and instrument localization.

DIRAC v2 Public Beta for the iPhone Available
Mainz, Germany, October 5th, 2009 — We are happy to announce the first public beta of the new DIRAC version 2 for the iPhone. Over the past few weeks, we have received numerous requests for an iPhone version of our DIRAC time stretch/pitch shift technology, since Apple is not providing their AUTimePitch AudioUnit for the iPhone. Until now, iPhone developers had to use their own methods to change pitch and speed of audio signals independently, as no commercial grade solution was available.
As of today, DIRAC v2 for the iPhone is in public beta test and we expect to release support for its full range of platforms this week. The LE version will continue to be free and all versions will be available for Windows, MacOS X, Linux and the iPhone. Upgrades for existing 1.x licenses will also be available.
For general information on the product please visit our DIRAC page at http://www.dspdimension.com/technology-licensing/dirac2/ which will also be updated to version 2 soon. Version 2 offers increased speed, a better preview mode, better formant correction, iPhone support, 64bit support and is now ANSI C callable.
If you want to participate in the beta test and download a fully functional beta version of the free LE version right now you can do so from http://beta.dspdimension.com/iPhoneTest.zip (please see the license agreement that comes with the archive). Please contact us with any questions or problems that you might have via our contact form.
