The DSP Dimension Releases DIRAC 1.5, Announces qDIRAC for Mobile Devices
Mainz/Germany, May 27th, 2009 - The DSP Dimension today announces that version 1.5 of its award winning DIRAC polyphonic audio Time Stretching & Pitch Shifting solution is now available for download. Version 1.5 fixes minor problems that were present in previous versions and makes the library ANSI C-callable. Version 1.5 might require minor changes to your code due to minor changes in the API, please see the enclosed documentation for more details. The free DIRAC LE version has also been updated and can be downloaded from The DSP Dimension’s “Download” page on http://www.dspdimension.com.
The DSP Dimension also announces “qDIRAC” a new version of DIRAC optimized for mobile devices/streaming applications. “qDIRAC” is optimized for Linux and covered by the same license as the desktop version. It has a considerably smaller memory footprint, leaves allocating memory to the caller so it can preserve state information across sessions and threads and is optimized to make best use of the limited MIPS that are available on mobile/embedded devices. The DSP Dimension expects to make it available at the end of June 2009.

Letter from the Author
Hello,
thank you all for your continued interest in our web site! In 2009 we will be celebrating the DSPDimension web site’s 10th anniversary and thanks to you we have come a long way and are now among the top 10 sites in the field.
Unfortunately, my schedule and the growing number of comments are currently preventing me from personally responding to all your great comments directly on our web site. Because of this I just wanted to remind you that we have a forum at http://www.surroundsfx.com/forum/viewforum.php?f=11 that would be more appropriate for anything more complex than a simple one-way comment. I am regularly checking the forum and there are quite a few other people there who can answer any questions you might have in case I am not available. The forum membership is absolutely free and anyone can register.
Again thank you for your interest in our web site and articles and I am looking forward to answering your questions in our forum as soon as possible.
Happy Thanksgiving and best regards
Stephan Bernsee
HeadAcoustics ArtemiS 9 Now Includes DIRAC
Mainz, April 17th, 2008 — The latest version 9 of HeadAcoustics’ software ArtemiS (short for “Advanced Research TEchnology for Measurement and Investigation of Sound”), an advanced measurement software that is industry standard for vibration analysis now includes DIRAC for time stretching and pitch shifting of measured data. Read the full article on new features in ArtemiS 9 here.
According to their web site, ArtemiS is a recording, analysis and playback software, which was developed to deal with tasks in the field of sound and vibration quickly and efficiently. Simultaneous listening, analyzing and interactive filtering is of vital importance when using ArtemiS. Because only then – while using your own ears – can sound problems be effectively detected or target sounds defined.
DIRAC Licensing Options Changed
Mainz, March 3rd, 2008 — The DSP Dimension today announce that effective immediately DIRAC will only be available for licensing on an up-front one time payment basis. Since nine out of ten of our licensees use the up-front option the recurring licensing fee of the annual licensing option involved too much bookkeeping on our part to be actually profitable. We are still open to customized licensing options if you cannot afford or don’t want the off-the-shelf options that we offer, in this case we kindly ask you to get in touch with us to provide you with a custom tailored solution. Licensees currently using the annual licensing option can switch to a non-recurring licensing contract by paying a one-time fee of EUR 980. Please get in touch with us in order to have your contract changed accordingly.
DIRAC LE 1.3 Released
Mainz, November 13, 2007 – The DSP Dimension announce the immediate availability of version 1.3 of their free commercial grade DIRAC Time Stretching and Pitch Shifting library for Windows and MacOS X. Version 1.3 fixes many minor issues that were present in earlier versions and integrates both the bug fixes and improvements from the PRO into the LE version. The new version is a free download off our download page.
Site Redesign
Mainz, October 21, 2007 — As this web site is slowly but surely approaching its ten years anniversary in 2009 we have decided that it is time for a change. We wanted to steer clear of the old plain html design that was messy to maintain and tedious to update and go for a fully configurable Blog system instead. We are happy to announce that the move to our new system has been completed in no time thanks to the wonderful WordPress software. The good news is that this allows you to comment on some of our articles, providing us with immediate feedback and help on how to improve things. The bad news is that some of our “fun stuff” articles had to go, because there was no way to conceptually integrate them with the new web site content. But worry not – we still keep the entire old site around for you in case you need something. You can find it at http://oldsite.dspdimension.com. Please bear with us if some of the new pages have broken links or missing images – we are in the process of double checking everything right now and expect to have it up and running by the end of this week.
