CSR boosts multimedia Bluetooth offering with virtual surround sound

admin — Fri, 27 Apr 2007 13:56:06 +0000

CSR announced it has added Sonaptic’s SoundStage Virtual Surround System to its BlueCore5-Multimedia Bluetooth technology to provide users with an improved hi-fi stereo audio experience. Mobile Bluetooth products will now be able to benefit from a richer and more engrossing stereo audio performance.

Sonaptic uses advanced psychoacoustic processing in its software that creates virtual speakers to ‘place‘ the user right in the middle of the sound. This virtual surround experience can be delivered on standard Bluetooth audio devices running BlueCore5-Mulitimedia, and requires an exceptionally low memory and uses very little processing power making it ideal for battery powered mobile devices.
Due to a high performance 24-bit 64 MIPS on-chip DSP, CSR’s BlueCore5-Multimedia platform is the only Bluetooth platform available which can support a variety of third-party audio enhancement algorithms. In addition, BlueCore5-Multimedia provides superior sound quality with a best-in-class signal to noise ratio of -95dB. » read more »

QSound Labs' stereo expansion technology now available on CSR's BlueCore5-Multimedia

admin — Fri, 30 Mar 2007 05:56:53 +0000

CSR says it has boosted its multimedia Bluetooth technology with the addition of QSound Labs’ QXpander technology. QSound offers a powerful suite of audio enhancements for digital playback that provides a richer, more natural and immersive enhanced audio for CSR’s BlueCore3 and BlueCore5-Multimedia systems. Music transmitted over Bluetooth via CSR’s BlueCore technology now benefits from spatial stereo expansion through QSound’s QXpander audio algorithms. QSound will be demonstrating its technology on CSR’s BlueCore Multimedia systems this week at exhibition Stand 463-A at the CTIA Wireless 2007, in Orlando, Florida.

QXpander technology uses purpose-specific algorithms for maximum spatial impact on headphones and speakers. The three-dimensional spatial processing adds new depth to music playback by expanding the soundstage beyond the physical limitations of speaker locations; this expands the acoustic image outside of the user’s head when using headphones. The sophisticated enhancement algorithms are particularly effective on highly compressed audio content such as MP3 and SBC. » read more »

Mobile users can now greet incoming callers with high fidelity music and audio instead of the common tones in use today

Coding Technologies, a provider of audio compression for mobile, digital broadcasting and the Internet, and SK Telecom, a mobile service provider in Korea, have successfully incorporated Coding Technologies’ aacPlus audio codec into SK Telecom’s Premium Color Ring Back Tone service (PCRBT) launched on March 13. The new aacPlus audio codec greatly improves the audio quality compared to the former service. The launch of SK Telecom’s PCRBT service constitutes a commercial proof of concept and is expected to impact the adoption of similar services in other countries. The first phone models supporting the new service are already available from vendors such as Motorola and Pantech.

Color Ring Back Tones allow mobile phone users to personalize their mobile phone service by selecting songs that callers hear when calling the user’s phone. Color Ring Back Tones are a much sought-after life-style accessory in the huge Asian markets with more than 12 million active users in South Korea. » read more »
