Using non-destructive coding techniques, CSR’s aptX audio codec for Bluetooth A2DP preserves the full “wired” audio quality of stereo transmitted over the 2.4 GHz ISM band from Laird Technologies’ BTM510/511and BTM520/521 wireless modules, each of which integrates an audio DSP.

“The Laird Technologies BTM510/511and BTM520/521 wireless modules meet the demands of designers who require a simple method for integrating high quality Bluetooth audio into their embedded solutions, including communication with another Bluetooth device while also utilizing CSR’s aptX audio codec technology,” said Chris Downey, Laird Technologies Product Manager, Telematics & Wireless M2M. “These solutions are priced competitively and unlike our competitors, the aptX technology is provided license free.”
