Acoustic Technology for Localization and Active Separation of Sources

To address DARPA’s interest in sensors and controls that can separate and locate intermixed sounds in an auditory scene, Physical Optics Corporation (POC) proposes to develop a new Acoustic Technology for Localization and Active Separation of Sources (ATLASS). This proposed device is based on clustering of extracted feature vectors. The innovation in concatenating complementary signal processing algorithms will enable the device to separate and localize individual acoustic sources from a complex scene. As a result, this device offers highly selective signal extraction and location determination in real time, which directly address the DARPA requirements. In Phase I, POC will demonstrate the feasibility of ATLASS by building and testing a prototype that can discern separate voices among a mixture of sounds and deliver proposed system requirements and design documentation, along with the firmware source code. In Phase II, POC plans to develop an enhanced prototype that meets specific CONOPS requirements.
