apt-X® Technology Optimizes Sound Quality in Bluetooth®-enabled Digital Entertainment Devices

St. Louis, Missouri, USA – June 14, 2010 – Laird Technologies, Inc., a global leader in the design and supply of customized performance-critical components and systems for advanced electronics and wireless products, today announced the licensing of apt-X® audio codec technology for use in its Bluetooth® BTM510/511and BTM520/521 wireless stereo audio modules.

apt-X technology optimizes the objective sound quality of stereo audio channeled over the 2.4GHz ISM band from Laird Technologies’ BTM510/511and BTM520/521 wireless modules. Each module incorporates the CSR BlueCore5 Bluetooth 2.1 system-on-a-chip which is used extensively in digital entertainment devices. Each module comes pre-configured with apt-X audio codec software, eliminating the need to program in extra firmware.

"By enhancing our Bluetooth modules with apt-X audio codec technology, Laird Technologies is able to offer the best possible stereo audio quality for our wireless audio module designs,” said Carl Baker, Laird Technologies Director of Sales, Telematics & Wireless M2M. “There is a marked improvement in the sonic purity of Bluetooth stereo audio with apt-X programmed in."

Designed by APTX, an established and proven provider of industry-leading audio compression solutions to the broadcast, professional audio, and consumer electronics industries, apt-X transparently delivers full “wired” audio quality over Bluetooth links. The non-destructive coding techniques used means that the quality of the original source audio file, be that of a CD or a compressed format (MP3, AAC, FLAC), will be preserved over the Bluetooth A2DP link.

"This strategic license agreement with Laird Technologies opens previously untapped Hi-Fi markets to apt-X stereo Bluetooth modules,” said Stephen Wray, APTX Vice President of Licensing. “The availability of Laird Technologies’ best-in-class Bluetooth modules pre-installed with apt-X enables high-end audio designers to deliver wireless, full-frequency bandwidth audio streaming, allowing for the richest possible stereo sound."
