The DSP Dimension Releases Dirac3
Mainz, October 22nd, 2010 – The DSP Dimension announces the immediate availability of Dirac3, the successor of its critically acclaimed time stretching and pitch shifting library for polyphonic audio. Dirac3 allows changing pitch and speed of audio independently of each other without sacrificing audio quality. It offers both realtime and non-realtime processing modes for different applications and speed requirements.
Dirac3 offers vastly improved processing speed, better support for mobile platforms such as the iPhone and iPad (including iOS4 and Accelerate) and specialized processing modes such as DiracRetune and Transcribe. DiracRetune complements Dirac’s pitch correction and can quantize and freeze pitch to the closest semitone. Dirac’s new content aware TranscribeMode allows extreme time stretching factors to slow down audio by as much as 400% without losing attack transients. As with previous versions a free Dirac LE library is provided. LE offers a subset of features and is limited to monaural recordings.
Dirac3 can be licensed as a cost effective mobile version (iPhone, iPad, OS 3.2 and iOS 4+) or as either a stereo STUDIO or a full-featured multichannel PRO desktop license (MacOS X PPC/Intel 32/64bit, x68 Linux 32/64bit, Windows 32/64bit) the latter of which also includes the mobile version.
Existing licensees who have licensed Dirac within 6 months prior to the release of Dirac3 can upgrade for free. An evaluation version of Dirac3 is provided upon request.

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.

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.
