Surround. Both cards include three governing feature sets for
managing sound holistically:
1. Intelligent Media Processing (IMP): The Philips software
foundation that constantly monitors the type of sound
input and renders it according to output.
2. Compelling 3D virtualization: Technology developed by
QSound Labs for Sound Agent 2 creates the absolute
best 3D audio experience for any headphone, stereo
speaker or multi-channel speaker system. State-of-the-
art algorithms eliminate the need for cross-talk
cancellation found in many solutions from other
manufacturers. The end result is an ultra-wide "sweet
spot" for strong positional perception regardless of
head movement and positioning, allowing listeners to
enjoy a true 3D surround experience with two, four,
or more speakers in any environment.
3. Comprehensive API support: Both cards include
extensive compatibility to existing standards, such as
DS3D, EAX 2.0, and A3D 1.0.
The Sonic Edge 5.1 also includes:
1. 5.1 Channel Surround from any source material: Stereo
sources from CDs, MP3s, and PC games are
transformed into 6 full channels of true surround
sound using QSound's exclusive QMSS 5.1 technology.
While other solutions simply mirror the front stereo
speakers in the rear channels, QMSS analyzes each
incoming signal and automatically approximates the
location of where each individual sound should be in a
surround environment. The result is a full 360-degree
wrap-around sound experience from all sound sources.
2. QSizzle and QRumble to supercharge MP3's: Uniquely
provides an energy boost to MP3 files that helps
restore compressed digital music to its original fidelity,
by compensating for lost harmonic detail (see
expanded technology description "Attacking MP3
Format Limitations"). MP3 files are have a notoriously
flat sound. Truly adaptive, this technology features
active multi-band filtering that continuously monitors
input signals and makes adjustments automatically.
