Introducing the Dirac Live Room Correction Suite

Easy-to-use software delivers powerful sound optimization for computer-based HiFi systems

Uppsala, Sweden - December 19th, 2012-Dirac Research AB (, sound technology provider to Rolls Royce, BMW, Naim Audio and other world leading brands, has announced the introduction of the Dirac Dirac Live Room Correction Suite™, a powerful software solution that delivers optimized sound quality for any PC or Mac®-based HiFi system. The software, which requires a microphone, measures the acoustic performance of the system within the listening room and optimizes playback performance accordingly, providing the most transparent music reproduction possible.

A point of emphasis with the Dirac software is that it optimizes all sound from the computer using any music/media player as well as standard sound output devices. It was designed to be very easy-to-use but also highly precise and without compromise in terms of sound quality and/or flexibility for the advanced user. Because the Dirac software uses the computer as a digital signal processing engine, there is no need for additional costly audio electronics. It is an ideal solution for anyone seeking better performance from their computer-based HiFi system.

"The Dirac Live Room Correction Suite has been tailored to the growing number of consumers who are using their computer as an audio source," explained Dr. Mathias Johansson, CEO at Dirac. "We have leveraged the processing power of the home computer, enabling each user to optimize their listening experience based on their existing speakers and environment. Our goal has been to offer a better sound quality upgrade than any other HiFi component can provide at the same price," Johansson concluded.

The Dirac Live Room Correction Suite is based upon an acclaimed digital signal processing technology born from years of research and development. Used by digital cinemas around the world, leading consumer electronics manufacturers and automakers such as Rolls Royce, BMW and Bentley, Dirac has become an established leader in loudspeaker and room optimization. Now available at a completely different price range than ever before, music aficionados will enjoy how the software tightens the bass, removes resonances, focuses the stereo image and makes voices smooth and clear.

The suite supports up to 8 channels and up to 24 bit resolution at a 96 kHz sampling rate. The technology is unique in that it corrects not only the frequency response but also the impulse response of the signal, in contrast with other solutions that do not optimize the impulse response. Correcting both the frequency and impulse responses yields remarkable improvements in the stereo image, clarity and overall reproduction of the music. MSRP for the Dirac Live Room Correction Suite is $850 (14-day risk free trial) with an introductory discount of 25% available now from Dirac (


"Our customers expect the ultimate in every experience and Dirac provides the ultimate within digital signal processing." - Mike Hanks, Senior Engineer at Bentley Motors

"I was completely amazed by the difference that Dirac made to my new studio....Now everything sounds just right! significantly more accurate across the whole frequency range plus the imaging is incredible" - Ian Wallman, Ivor Nevello-nominated record producer, UK.

PureLink - HCE III TX/RX: 4K HDR over HDBaseT Extension System w/ Control and Bi-Directional PoE

The HCE III Tx/Rx HDBaseT™ extension system offers full HDMI 2.0 compliance supporting HDR (High Dynamic Range) and 4K@60Hz with 4:4:4 chroma sampling. Featuring PureLink's proprietary Pr©cis codec, a light compression technology, the HCE III can transport Ultra HD/4K, multi-channel audio, and High Dynamic Range (10 bits support) content over a single CATx cable. The HCE III provides HDMI extension up to 130 feet (40 meters) at Ultra HD/4K and up to 230 ft. (70 meters) at 1080p over category cable with embedded multi-channel audio, CEC pass-through, bi-directional RS-232 and IR control, and PoE - all with zero loss and zero noise. The HCE III Tx/Rx also supports Dolby TrueHD, Dolby Digital Plus and DTS-HD Master Audio plus LCPM (up to 192 kHz). Additionally, the low profile "slim box" enclosure design make the HCE III ideal for limited space installation environments, such as behind flat panel displays and video walls.
