PITCHMAP Takes Musical Composing to the Next Level
“A remixer’s dream come true” you might call this recent development created and marketed by newly founded company Zynaptiq out of Hannover, Germany, that we’re proud to be associated with.
PitchMap is not just your regular kitchen pitch shifter – it is a tool based around music recognition that actually de-mixes and pitch shifts instruments in a mix at the same time. Oh, and did I forget to mention: yes, it does all of this in real-time, on an off-the-shelf Mac (Windows support is being worked on). Not only allows this tool to correct for off-key arrangements after all the musicians have left the stage to do more interesting stuff and join the festivities in the VIP lounge. It also allows for real-time manipulation of all your favourite hits to suit your personal mood and preferred musical style – directly by interacting with them on your own MIDI keyboard. It’s like you had all the musicians right at your fingertips performing to your commands. If you ever wondered what Michael Jackson’s “Stranger in Moskow” sounded like after he had his 3rd round of Gorbachov Vodka you can use PitchMap to change the scale accordingly to compensate for the “drift”, or, if you’re so inclined, you could listen to any classical recording being played in another key or mood.
Check out their video and web site at http://www.zynaptiq.com and if you’re on a Mac make sure you give their free demo version a spin.
With this tool, you too can change the laws of physics!
Tom Zicarelli Releases AudioGraph (iOS)
Mainz, Germany, December 8th, 2011 — Software developer Tom Zicarelli has released an open source iOS audio processing graph demonstration called “audioGraph”. According to the author the work is in part based on the DSP Dimension pitch shifting tutorial.

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).

The DSP Dimension Releases Free Pitch Shift AudioUnit Plug-In “DiracFxAU”
Mainz, Germany, September 14th, 2011 – The DSP Dimension, one of the leading providers of DSP technology for music and speech applications today announces 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, MacOS X, Windows and Linux. A feature-limited DiracLE edition of the SDK is available to developers at http://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 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 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.
