The DAP accepted only PCM sources (no DSD) and, at the time of the review, only up to 24/96. In its original implementation, the Dirac Audio Processor (DAP) acted as a virtual audio device, inserted into the signal chain between your music program and your DAC. I reviewed the original release of the Dirac Live Correction System (DLCS) in 2014 and installed it into both my systems, for multichannel and stereo. Not only was it more flexible and precise than those convenient built-in products it was audibly more capable of dealing with problematic room effects. For those of us who accepted the job, it was an ear-opener. As such, its use was limited to the more intrepid and technical audio consumers.
DIRAC LIVE VS DIRAC FULL INSTALL
When it first appeared, Dirac Live was a software product that the user could buy, download, and install into a Windows or Mac computer used for music playback (footnote 1).

There's a place in the two-channel world for room-correction DSP. And yet, these days, most two-channel audiophiles spend at least some of their time listening to digital, whether it's from a streaming service, locally stored downloaded or ripped files, or old-fashioned shiny silverdiscs. Stereo listeners are much more likely to integrate analog sourcesturntables, reel-to-reel tape, and old-fashioned radio tunersinto their systems and to resist converting that pure analog signal to digital so that it can be processed and room-corrected. Small, standmount speakers often benefit from uncorrected room modes to extend their range. In the two-channel world, things have proceeded much more slowly. Most work well, providing precise level balance, compensating for unequal pathlength differences, and correcting in-room frequency response for all the speakers. Today, some arrive installed in AVRs and preamp-processors others come as standalone devices or computer software. Audyssey was the first such utility to gain wide acceptance.
DIRAC LIVE VS DIRAC FULL SERIES
Help quickly came in the form of setup utilities that required no knowledge of acousticsonly a willingness to position a microphone for a series of measurements and let the system do the rest. Its fans were expected to install several loudspeakers in a full-range setup that included at least one speakerthe subwoofer(s)that functioned exclusively in the problematic bass region. Arcam’s AVR10, AVR20, AVR30, and AVR40 units, and AudioControl’s Concert XR-4, XR-6, XR-8 and Maestro X7 and X9 will also soon be equipped with Dirac Live Bass Control Complete.Adoption of DSP-based speaker-and-room correction in home theatera parallel universe to audiophiliais almost universal. This processing enables the subwoofers to be positioned anywhere in the room for aesthetic reasons, without sacrificing performance for design, or vice versa, says the company.Īll StormAudio, Bryston, and Focal models currently equipped with Dirac Live Room Correction are now also equipped with Dirac Live Bass Control (Complete), as will soon be true of all JBL Synthesis AVRs. The feature also corrects the low-frequency sound waves produced by the speaker pair, so the bass produced by each speaker is in sync with the system. It then identifies gaps in the sound waves and distributes bass evenly across the room.
DIRAC LIVE VS DIRAC FULL MANUAL
This newest feature is available in three tiers: Enabled, for manual single subwoofer management Limited, for automatic single-subwoofer management and Complete, for AI multi-subwoofer management.ĭirac Live Bass Control aggregates measurement and location data from each subwoofer to determine how a system’s bass is distributed throughout the room. “Dirac Live Bass Control measures and phase corrects both the speakers and subwoofers across all frequencies to produce enhanced bass clarity and improved bass tone evenness throughout the room.”ĭirac Live Bass Control is the second feature offered through the Dirac Live room acoustics product, which also includes the Dirac Live Room Correction room calibration tool. “Speaker and subwoofer sound waves bounce throughout a space and collide with one another to create crossover areas with uneven bass distribution,” noted Thorin in the announcement statement. Powered by machine learning and AI, Dirac Live Bass Control co-optimizes a system’s subwoofers and speakers to deliver consistent and accurate bass throughout a room. According to Niklas Thorin, Dirac’s GM of High Performance Audio, the solution is now featured on AVR units from Bryston, Focal and StormAudio, with units from Arcam, AudioControl, JBL Synthesis and others soon to follow. Dirac Live Bass Control, the latest feature of Dirac Live, is now officially available for home theater and audio enthusiasts in a range of models from several A/V receiver (AVR) manufacturers, Swedish audio technology company Dirac has announced.
