The QSurround family of algorithms renders high-quality,
multi-channel virtual surround audio with maximum spatial
impact over stereo headphones, stereo speakers and multispeaker surround systems, creating a powerfully immersive
listening experience.
QSurround has been implemented in a wide range of consumer
entertainment products including PC sound cards, laptop
computers, DVD players, TVs, portable stereos and home
theater systems from manufacturers such as AIWA, Philips,
RCA, Sharp, Sanyo and Toshiba.
Product Family
The QSurround family of 3D audio virtualizers consists of:
QSurround HD™, a multi-channel virtualizer specifically designed
for playback over stereo speaker systems.
QSurround 5.1™, a multi-channel virtualizer that works with any
multi-speaker configuration, whether arranged traditionally or
front oriented.
QSurround Headphones™, a multi-channel virtualizer employing
unique HRTF algorithms for headphones in conjunction with
ambient environment simulation (a virtual room) that provides
context for the content.
All of these virtualizers can be complemented with the addition
of optional bass and high frequency enhancement algorithms,
QSizzle and QRumble, as well as our speech enhancement
algorithm, QDialog.
QSizzle™
QRumble™
QDialog™
An adaptive mid to high-frequency spectral enhancement
that restores a natural-sounding sonic punch to highly
compressed audio formats like MP3 by selectively adding
upper spectrum energy according to the real-time
characteristics of the input signal.
The low-frequency counterpart to QSizzle, QRumble also
adds energy in a selective fashion, bringing substance and
warmth to the low end spectrum without overloading on
loud passages.
Enhances speech and vocals for music and movie soundtracks, providing improved clarity and intelligibility.
