HEADSPEAKER – 5.1 HEADPHONE SYSTEM
1. G eneral instruction s
HeaDSPeaker 5.1 headphone system makes realistic, immersive multichannel audio
playback possible using regular stereo headphones. The underlying technology is based
on modeling the human auditory mechanisms using advanced signal processing
algorithms and real-time head tracking.
To be able to produce a surround sound experience that satisfies even the most
demanding users, head tracking feature is a necessity. For this purpose, HeaDSPeaker
system provides tracking sensors that can be attached to virtually any regular
headphones.
The ”brains” of the system is a DSP unit, which acts as a transmitter for the tracking
sensors. DSP unit processes multichannel audio signal in such a way that the user
perceives sound directions as if the sound was actually played back using a set of
surround loudspeakers.
HeaDSPeaker supports lossless 5.1 (or 7.1) PCM-audio via USB-bus, or alternatively
surround-encoded multichannel audio via analog stereo connector.
Analog stereo audio will be decoded to multichannel format using DSPeaker's proprietary
DSP-logic -decoder. DSP-logic can decode the most commonly used multichannel
formats in a way suitable for headphone use. This way HeaDSPeaker supports sound
sources including surround-encoded TV-broadcasts and the latest gaming consoles
among others.
To enjoy surround sound at the maximum, it is recommended to take a couple of
minutes to configure the system based on personal qualities. HeaDSPeaker package
contains the required computer software for easy configuration and diagnostics. At the
moment, only Windows XP and Vista plattforms are supported. A Macintosh version is
under development.
