Dirac software allows "to feel" the premises – to measure its acoustics. It updates the sound offsetting all the defects. Henrik Svensson demonstrated it in the reference room. The room covered with special panels on the walls seemed to be acoustically ideal, but as they turn on "room correction" the tone balance is getting perfect, the sound is more dimensional and bass is getting denser.
"...it comes gone to the sound and even though I have a very good monitoring system, the review unit won't be going back to Hong Kong. I will be buying it and sending them the money instead. Enough said."
Residential Systems review
"Unparalleled audio performance and world-class Dirac room correction elevate this amazing receiver above the pack."
Residential Systems magazine article
"The system corrects the unnatural, overly localized audio inherent in headphones, by positioning a phantom image in front of the listener, where it remains as the point source, even when the listener rotates his or her head. The sound opens up as if you're listening to speakers, rather than from headphones."
Secrets of Home Theater and High Fidelity article
"I selected what ever track I wanted and as I listened through the phones and turned my head, the performance stayed fixed in the same spot but it was as if I had turned in a real performance and it was effectively simulated. It was eerily convincing."
"Turning the enhancement on and off through the app quickly illustrated a much wider and fuller soundstage, without fuzziness or bloat was able to be experienced with Dirac Panorama Sound. It was a very enlightening experience!"
Dirac Live's unparalleled ability to overcome your room's significant acoustic issues must be heard to be believed.
"First of all, I think we're still a few years away from really convincing 3D audio on headphones. There are still too many unknowns that need sorting through—personalized HRTFs; better headphone transducers; how to economically get all number crunching with head movement in order to commercialize it. To my mind, any solution out there right now will be largely incomplete, bleeding edge technologies. Previous to CES, that idea tainted my expectations; I really didn't think I'd hear anything really impressive when it came to 3D audio. I was wrong."
"Dirac is becoming the go-to choice for room correction in high-end products and its demo of technology destined for virtual reality use was convincing. New surround pre-pros using Dirac were announced by Emotiva and Arcam. The latter's demo of Atmos with Dirac (with an existing receiver model and a new four-channel amp) was the best surround sound of the show."
"Dirac Research specialises in platform-optimized sound enhancement technology and its Dirac VR platform features the latest patent-pending dynamic HRTFs (head-related transfer functions) that consider the isolated movements of the head in relation to the human torso."
"While the visual and interactive elements of these headsets have been iterated and improved, the audio has been somewhat of a stumbling block. Sure 3D audio formats such as Dolby Atmos, DTS:X and Auro-3D can give the illusion that you’re actually standing in a 3D space – but it’s not enough to trick the brain that you’re actually there.
That’s where Dirac comes along."
Review by Home Theater Shack forums:
"Another Nail Through My Heart - Squeeze - 90 LU
I love what DL does to vocals, sharp, almost hard, but with no pain. Cymbals are gorgeous. Bass is even, perfection. I sounds like the mixing and mastering were all redone by Dirac Live, every part sounds perfected." Read it!
Review by: Secrets of Home Theater and High Fidelity
"One more point – the unit makes it easy to toggle the Dirac Live on and off. When I would turn it off while listening to vinyl, the soundstage collapsed dramatically. When on, the Dirac spread the stage as wide as possible and opened up the top end in a way that I cannot fully explain with just words. It is something you must experience for yourself." Read it!

Check out this in-depth review on OnePlus 3, OnePlus’ latest smartphone model using Dirac Power Sound for its speaker system. The audio performance of OnePlus 3 is thoroughly introduced and highly rated by the reviewer.
“Moving on to the star of the show, the OnePlus 3, I moved my usual set of music sets, which involve some club, trap, EDM, PDB mixes and some trances, and fired up a club set…Overall it was very balanced produced sound and a very enjoyable experience…I favor the speaker of the OnePlus 3 over the iPhone's, since it is much more accurate when playing the music and sounds a lot louder with no audible distortion that may ruin your experience…This device is a definite green light for audiophiles on a budget. This phone swears to be an audio veteran...” Read it!

Review by: Secrets of Home Theater and High Fidelity
"The improvements brought about by Dirac Live were impressive: bass reproduction elevated to a level I had never heard before in my room; dialog intelligibility improved, as did the consistency of timbre across my loudspeaker array. I never felt the urge to disengage Dirac Live." Read it!
Review by AVForums:
"If that was all the AVR850 was capable of we would have been impressed but as soon as we applied the Dirac Live room correction then entire performance just stepped up a gear. It's an over-used cliché but when applying Dirac Live the room and the speakers simply disappeared, creating a wonderfully realistic audio experience. Any sonic characteristics that could have been caused by the room itself evaporated and all that was left was the original sound design."
"The combination of Class G amplification and Dirac Live results in one of the best-sounding receivers we've tested." Read it!
Review by Hi-Fi Choice:
"When I switch Dirac Live on, there is a quite profound change to the sound. I’ve heard many ‘room correction’ systems and normally I sit listening to the sound of heavy, ham-fisted DSP that solves some problems while introducing others. Not so here though; regardless of source it works a treat." Read it!
