About QSound® Bluetooth® Audio
In today’s consumer environment, wireless means flexibility,
freedom and mobility – no cables, no clutter, no hassles. Whether
wired or not, consumers expect excellent performance and quality.
QSound and CSR deliver exactly that – top quality Bluetooth wireless
capability. CSR’s BlueCore3/5-Multimedia single chip radio and
baseband IC enhanced with QSound’s leading stereo sound stage
expansion, surpasses consumer expectations with an impressively
detailed audio experience.
QSound Bluetooth Audio is a compact, high-performance digital
audio processing software solution drawn from QSound Labs’
ground-breaking 3D spatial algorithms. This technology represents
the culmination of over 15 years of PC host and DSP audio software
development and product deployment by QSound Labs, Inc., a world
leader in sonic innovation.

Feature Description
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 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.
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.
