“Next was a demo of Dirac Bass, which really amazed me. I was first shown a basic $40 speaker from IKEA. Sound quality was acceptable, with a flat and even sound profile, that had no real distinction between highs, mids, and lows. Once the speaker utilized Dirac Bass, you could really hear the difference. This went beyond using an equalizer preset that was set to favor the lows, which would typically result in the highs and mids being drowned out. Dirac Bass gave you a deep sounding low while keeping the other tones intact, with no distortion and overall evenness.”
"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." Read more about Dirac 3D Audio and headphone surround sound here.
"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...."
