Demonstrating the Audio Pre-processing Reference Design for Voice-based Applications on C6747


Date: September 1, 2017

This video demonstrates the audio pre-processing system reference design for voice-based applications using the OMAP-L137/TMS320C6747 Floating Point Starter Kit and the PCM1864-Based Circular Microphone Board (CMB) Reference Design. This reference design uses multiple microphones, a beamforming algorithm, and other processes to extract clear speech and audio amidst noise and other clutter.  The rapid increase in applications that are used in noise-prone environments for voice activated digital assistants creates demand for systems that extract clear voice from noisy environments.  The TIDEP-0099 reference design uses a microphone array and a sophisticated signal processing to extract clear audio from noisy environments.
