By Noel Randewich SAN FRANCISCO (Reuters) – Chipmaker Audience Inc is acquiring a Silicon Valley startup in hopes of helping build smartphones that can figure out what you need at any time of the day, or even how you’re sleeping at night. Audience announced late on Tuesday it is paying $41 million for Sensor Platforms, which creates algorithms that help analyze data from sensors on smartphones and other mobile devices. Mixing Sensor Platforms’ technology with its own audio processing expertise could give Audience a leg up in improving how smartphones and other gadgets interpret what activities their owners are doing and how to help them. Samsung and other manufacturers are packing gyroscopes, cameras, microphones, barometers and other sensors into smartphones.
