Feature Description
QXpander®
The QSound Competitive Edge
QSound’s proprietary QXpander 3D spatial processing literally
adds new dimensions to music playback, expanding the sound stage
beyond the physical limitations of speaker locations, and enlarging the
acoustic image outside the listener’s head when using headphones.
• Top quality audio enhancement
algorithms for stereo headphones,
speakers / docking stations
QXpander employs purpose-specific algorithms for maximum spatial
impact on headphones or speakers. Speaker-targeted 3D processing
is optimized for narrow speaker geometries and can be OEM-tuned for
peak performance on front, rear, or side-firing speaker configurations.
QSizzle™
QSizzle is an adaptive mid to high-frequency spectral enhancement,
selectively adding upper spectrum energy according to the real
time characteristics of the input signal. QSizzle restores a natural
sounding sonic punch to highly compressed audio formats like mp3
resulting in lively, sparkling highs without the strident, harsh sideeffects of simple frequency boosters.
QLimiter™
A high-efficiency, anti-saturation dynamic range controller, QLimiter
handles any combination of signals and extreme effects settings,
eliminating output distortion with surprisingly little CPU bandwidth.
•
Industry’s best performance:
- Lowest memory and MIPS
- Ultra low system overhead
- Minimal effect on headset
playback times
- Tunable for all narrow geometry
speaker configurations
• Proven track record and established
brand recognition
Other Technologies Available:
QRumble™ dynamic low-frequency enhancement.
QCompressor™ dynamic range control.
QLoudness™ Fletcher-Munson equalization curve.
