QSound® Bluetooth® Audio
Application Overview QSound® Bluetooth® Audio stereo enhancement for CSR BC MP3 Player & BC3/5 Multimedia IC’s About QSound® Bluetooth® Audio Mobile Phones Music Players Earphones Speakers Car Systems 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 audio technologies surpass 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 20 years of PC host and DSP audio software development and product deployment by QSound Labs, Inc., a world leader in sonic innovation. Feature Set Description The QSound Bluetooth audio suite enhances CSR Bluecore 3/5 multimedia ICs with: •QXpander ® natural sounding, less fatiguing 3D sound stage expansion for earphones/speakers. QSound Labs, Inc., Partner CSR eXtension Program •QSizzle™ active mid/high-frequency spectral enhancement. •QRumble™ active low-frequency spectral enhancement. •QEQ™ static multi-band equalization with presets. •QLimiter™ anti-saturation dynamic range control. QXpander® 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. This results in a more natural and less fatiguing listening experience. 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. The QSound Competitive Edge • Top quality audio enhancement algorithms for stereo headphones, speakers / docking stations • 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 Leaders in Digital Audio Innovation QSound® Bluetooth® Audio Feature Set Description Technical Specifications & Implementation Data continued QSizzle™ 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 harsh side-effects of simple frequency boosters. Audio solutions by QSound Labs have been rigorously optimized with the participation of our major industry partners focusing on three critical requirements: QRumble™ The low-frequency counterpart to QSizzle, QRumble also adds energy selectively, bringing substance and warmth to the low end of the spectrum without overloading on loud passages. QEQ™ Multi-band equalization for custom shaping frequency response with 17 different presets including Classical, Jazz, Rock and Pop. QLimiter™ A high-efficiency, anti-saturation dynamic range controller, QLimiter handles any combination of signals and extreme effects settings. Eliminates output distortion with surprisingly little CPU bandwidth use, ensuring consistent high-quality playback. • Quality • Processing performance • Memory footprint. You can expect at least 25 to 50 percent savings on MIPS and memory footprint when compared to competing solutions.
