Revolutionary 3D Sound Technology Set to Disrupt Stereo Audio Systems

The development of positional 3D audio is poised to revolutionize the way we experience sound, especially in video-conferencing, with the chief executive of Aureal, Kip Kokinakis, predicting that it may sound the death knell for traditional stereo sound systems. Aureal's proprietary A3D technology, which has been used in VR labs, theme parks, and flight simulators, creates a more immersive experience by simulating the acoustic response from various materials and compensating for atmospheric attenuation and Doppler shifts.

Key Takeaways:

• Aureal's A3D technology uses "head-related transfer functions" to create a more realistic sound experience, which has been applied in various fields such as gaming, film soundtracks, and home cinema.
• The technology can project additional virtual speakers around a room, reducing the need for multiple speakers and making it a cost-effective solution.
• Ten years of research have resulted in filters that process digital signals into more realistic sounds.
• The A3D technology has been used in about a dozen games, with over 100 in development, and has also been employed in the recording of sound tracks for films such as Twister and The Cable Guy.
• Aureal aims to bring 3D sound technology to the Internet, which will significantly impact video-conferencing by enabling more realistic audio-visual synchronization.

Statistics:

• 10 years of research have been spent developing the A3D technology.
• 100 games are currently in development using the Aureal system.
• 12 games are already available that utilize the A3D technology.
• The A3D system can project virtual speakers around a room, making it a more cost-effective solution than traditional home theaters.
