Prosoniq TimeFactory v2.5 Now Available for Download
Karlsruhe, Germany, May 17th, 2013 – Prosoniq is happy to announce the immediate availability of TimeFactory version 2.5, which is a free download for all registered users.
TimeFactory is a standalone application for polyphonic time and pitch manipulation based on our DIRAC technology.
The following enhancements are implemented in this new version:
• Added capabilty to split and export joined channel files as individual channels (keeping the original names)
• Added native support for Sony WAVE64 and EBU MBWF/RF64 file formats for processing and export of large files (ProTools 10+ compatibility)
• Updated Dirac algorithm to latest v3.6.2
• Added Dirac’s transcribe mode
• Better usage of screen real estate
• Removed support for PPC machines
• Many minor fixes and usability improvements
PLEASE NOTE THAT THIS IS AN INTEL-ONLY VERSION. As of version 2.5 Prosoniq no longer supports PPC machines. Please note also that they recommend MacOS X 10.6.8 or better when using this application.
You can download the new version from their updates page at http://support.prosoniq.com/cgi-bin/register?service=begin_update
Using Dirac with FMOD to Change Pitch and Speed of Audio in Real Time
This tutorial outlines a way to use Dirac to change pitch and speed independently of each other using FMOD to process and play back sound in real time. The example presented here uses FMOD’s streaming sound API but can be easily adapted for offline processing and other use cases as well. Read more
Max/MSP: diracLE~ external by Timo Rozendal
September 23, 2011 - Time Rozendal releases a high quality timestretching and pitchshifting external with autotune option for Max/MSP on the Mac. The package includes 3 Max for Live devices as well. The external is based on the free LE version of DSP Dimension‘s Dirac algorithm. You can use it to play from a buffer~ without latency added, or alternative you can place it in an audiostream (in this case you have quite some latency, but luckily hosts like ableton live correct for this automatically).

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
Dirac Time Stretch v3.2.5 Adds Realtime Examples and iOS 4.3/Xcode 4 Compatibility
Mainz, Germany, April 6th, 2011 — The DSP Dimension announces the immediate availability of version 3.2.5 of its critically acclaimed time stretching and pitch shifting technology Dirac. This new version improves stability on all platforms and adds new realtime processing example projects for iOS and MacOS X. This version also adds full compatibility with Apple’s new Xcode 4.
DiracLE and PRO evaluation have already been updated with the other versions to follow later this week.
Dirac 3.2 Now Available For Download
Mainz, Germany, November 30th, 2010 — The DSP Dimension announces the immediate availability of version 3.2 of its critically acclaimed time stretching and pitch shifting technology Dirac. Version 3.2 is available to all licensing partners and also to the general public via the free DiracLE version for MacOS X, Windows, Linux and the iPhone, which can be downloaded from http://dirac.dspdimension.com
New in version 3.2:
- [MacOS X][iOS]: Improved performance of vectorized code for kDiracLambdaPreview and kDiracLambdaTranscribe
- [iOS]: Compiled against latest iOS 4.2 SDK
- [iOS]: Removed unsupported UNIX symbol that caused the linker to fail when compiling for simulator target
- Improved speed of formant correction, up to 2.4x on vector-enabled platforms
- kDiracPropertyUseConstantCpuPitchShift in combination with kDiracLambdaTranscribe could cause unexpected results
- fixed crash with kDiracLambdaTranscribe and sample rates other than 22.05kHz and 44.1kHz
- fixed gain change when using kDiracLambdaTranscribe
- Removed cache warning messages
- Fixed formatting error in parameter output when using DiracPrintSettings()
- Optimized memory footprint when using kDiracLambdaTranscribe
- Introduced kDiracPropertyCacheMaxSizeFrames and kDiracPropertyCacheNumFramesLeftInCache property constants
- Added cross platform time measurement utilities, DiracStartClock() and DiracClockTimeSeconds() to keep the example projects more readable
- Added CPU usage measurement tools (DiracPeakCpuUsagePercent())
Dirac 3.1 Released
Dirac 3.1 was released this morning. Version 3.1 adds the following features:
1. Pitch detection: DiracRetune now allows getting and setting of the fundamental frequency. This can be used to detect the average pitch of an audio segment.
2. External pitch control: DiracRetune now allows to manually adjust the pitch of the audio signal, in order to create melodic phrases programmatically or via MIDI.
3. Constant CPU pitch shifting: We added a new kDiracPropertyUseConstantCpuPitchShift property that allows enabling constant CPU load pitch shifting. This affects all modes that support pitch shifting (kDiracLambda1-5, kDiracTranscribe). In previous versions, raising the pitch would increase CPU load proportionally. Note that this property has some impact on quality when upshifting pitch so it is off by default and its use should be strictly limited to realtime processing/previewing.
Version 3.1 is available to all licensees of Dirac 3. A new DiracLE version is also available from http://dirac.dspdimension.com. DiracRetune is not available in DiracLE.
Dirac Version 3.03 Now Available
Mainz, November 1st, 2010 - The DSP Dimension announces today the release of version 3.03 of its critically acclaimed time and pitch manipulation software Dirac. Version 3.03 has already been made available to all licensees that have a version 3 license plan. An evaluation version is also available upon request, please use the DSP Dimension contact form to request access to the technology evaluation server.
