Dirac Bass is latest breakthrough solution that enables smartphones and portable speakers to reproduce bass that is deeper with higher transparency than ever before. In speakers, bass performance is all about moving as much air as possible. However, micro-speakers, like those used in smartphones or portable speakers, cannot move the amount of air required to reproduce the really deep bass content that is key to a rich listening experience. Dirac Bass solves this problem by combining a classic psychoacoustic approach with new breakthroughs in digital signal processing.
- Firstly, extends perceived bass tone by up to 3 octaves
- Secondly, enables bass tones as deep as 30Hz to be audible
- Thirdly, reproduces natural, clean, and balanced deep bass
- Finally, perfect for smartphones and portable speakers
Lower risk for speaker damage
When micro-speakers attempt to produce pure bass tones, they easily get over-driven, causing audible distortion and ultimately speaker damage. By shifting bass tones to higher frequencies, Dirac Bass improves the health and longevity of the speakers.
Room for louder sound
The removal of some of the original bass content results in new headroom for speaker excursion. This then can be exploited to increase the loudness of the full band playback.
Freedom to use smaller speakers
Dirac Bass also allows manufacturers to utilize smaller speakers – which often cost less – while still delivering a significant upgrade in bass reproduction. These smaller Dirac Bass-enabled speakers require less power to be driven, which results in extended battery life for power-constrained mobile devices.
Dirac Bass is used exclusively in conjunction with Dirac Panorama Sound or Dirac Power Sound, Dirac’s suites of sound optimization solutions for mobile devices.
Sub-optimal bass performance can be the product of speaker driver properties or any other downstream post-processing audio system component. However, regardless of the cause, Dirac Bass is the ideal solution to improve the bass reproduction of any small speaker setup.
Improved performance in upcoming smartphones
Dirac announced Dirac Panorama Sound, which optimizes speakers that- positioned close together. You can find their technology in the OnePlus 6 and OnePlus 6T as well. Their latest addition, Dirac Bass, is a feature that improves bass performance for tiny speakers in smartphones.
Dirac is using a clever trick to achieve this. The tiny speakers in smartphones are simply not able to reproduce deep bass notes. To get around that, Dirac Bass plays a “combination of artificially generated overtones that are several octaves higher”. This tricks the human mind into perceiving the sound as deep bass.
