NTT Advanced Technology (NTT-AT) Corp. has announced the availability of an echo canceller software with noise suppression capability for use in a wide range of hands-free terminals and systems.

Available as a library for Texas Instruments' C54X series of DSPs, the software is based on the echo and noise cancellation technology developed by NTT Cyber Space Laboratories, and is targeted at manufacturers of car navigation systems, cellphones, PDAs, and videoconference systems.

When used with a hands-free terminal in a vehicle or with a videoconference system, the software eliminates both the noise of the running vehicle and the surrounding environment and the echo generated by the sound from a loudspeaker.
