1.1 Overview
Incorporating the latest Fortemedia technologies for removing ambient noise and acoustic echoes, the FM1288 preserves voice naturalness for greater speech intelligibility in a variety of noisy automotive enviroments. Designed to be compatible with a wide range of host processors and blue-tooth devices, the FM1288 voice processor is designed for easy system integration.
The FM1288 provides system designer the flexibilities to customize each processing module and fine-tune the algorithms to the unique needs and acoustic path characteristics of the manufacturer’s automotive model cabin or handsfree communication device.
