Audio

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.

New Compact Accessory Provides Unique Audio Technology, Making Music Portability for Music Phones and MP3 Players Easy for the Home and Office

Kyocera Wireless Corp. has announced the Kyocera Bluetooth® Music Gateway for enhanced mobile music portability to entertainment systems. This compact and easy-to-use universal accessory uses Stereo Bluetooth wireless technology to free digital audio files from personal music players such as cell phones and MP3 players, enabling a wirelessly-controlled full room experience over home and office stereos* or Bluetooth-enabled headsets.

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.
