Acoustic-Event Detection

RAMP enables long lifetimes for battery-operated devices that can detect an alarm, glass-break, or other sound. 

What if there were a device that could last years on a single battery, differentiate between the sounds in your home, and intelligently alert you only when it detects signs of trouble? The Aspinity RAMP chip enables a new generation of devices that can do just that – all while maintaining a long battery life and safeguarding personal privacy.

Power-Efficient Acoustic Event Detection

Today’s always-listening devices continuously digitize and then process all incoming sound in a digital signal processor. The majority of them then transmit this data to the cloud. The results of this massively inefficient digitize-first architecture — which requires constant digitizing, processing and transmitting all incoming data, relevant or not — either forces designers to use wall power or hampers product usability by requiring frequent battery recharge or replacement. Fortunately, an analyze-first architecture solves this problem.

The Aspinity RAMP chip can be programmed to detect specific audio events prior to digitization. Only when it detects an event, such as a specific type of alarm or a dog bark, will it wake up the rest of the always-listening system to alert the user that an event has been detected. Eliminating the digitization and processing of irrelevant data saves enough power to support the development and deployment of situationally intelligent wireless, battery-operated devices.

Additionally, and perhaps more importantly, the RAMP chip helps to safeguard user privacy. By so dramatically reducing system power and data requirements, the RAMP chip can be combined with a low-power DSP to enable complete localization of the always-listening solution on the device. No data is transmitted to the cloud, enhancing user privacy.
