Last year was a year when there was a great deal of interest in "spatial audio." There are various techniques for providing a three-dimensional sound field, but here we will introduce "Dirac Virtuo".
Dirac Research of Sweden, which developed Dirac Virtuo, is a well-known company in the field of room tuning and room acoustics in the overseas audio field. Dirac Research is famous for software called "Dirac Live" that automates everything from acoustic measurement to equalizer generation using a digital filter, and DSP hardware that supports it. Optimal sound is achieved by the listening position and the shape of the room.
Clear Audio Alpha
By the way, Dirac Virtuo has been in the limelight when the "Clear Audio Alpha" wireless headphones that adopted the technology at CES 2022 recently won the Innovation Award of CES 2022.
The Alpha is Clear Audio's flagship model, equipped with the trendy adaptive ANC. Furthermore, by installing Dirac Virtuo, the sound field can be expanded and a movie theater-like sound can be provided. Dirac Virtuo for Bluetooth Headphones converts regular stereo audio into 3D audio. It is said that the digital filter cultivated in Dirac Live is applied to this technology. Dirac Virtuo also has a technology for smartphones and tablets equipped with a multi-speaker called "Dirac Virtuo for Mobile Audio".
In addition, content-based processing has been added as a new feature of Dirac Virtuo. It can analyze the contents of existing stereo audio, generate multi-channel audio, and use it in existing multi-channel systems. There is no need to add a DSP, and it is said that it is possible to realize natural sound quality with less distortion than competing technologies with its own technology.
This technology will first be applied in the field of car audio, but eventually it may be applied to home audio technology and experienced at home.
