QUALCOMM has integrated Philips’ LifeVibes Voice sound enhancement software onto its Mobile Station Modem (MSM) chipsets. The echo-canceling technology is designed to improve the acoustic performance of 3G mobile handsets and improve the clarity of conference and hands-free calls.
QUALCOMM said the echo-canceling sound enhancement technology would enable users to make clear and full-duplex conference, videoconference and hands-free calls without audial interference from stationary background noise. QUALCOMM will initially provide support for echo-cancellation software on Enhanced Multimedia Platform MSM6550 and MSM6275 chipsets, both of which are compatible with CDMA2000 and WCDMA (UMTS) networks. Additional acoustic performance improvements to remove background noise using a dual-microphone spatial filter are planned for the Convergence Platform, achieved through the integration of another LifeVibes Voice product, the Noise Void background noise eliminator.
