Audio provides a means of communication, improves usability, and delivers entertainment. It can transform the mood of an environment, help us escape a noisy commute, assist us in machine interface and improve the quality of life for the visually impaired. Adding audio to your application enhances its ability to meet the needs of your customers. Bringing your product to market with the right mix of performance and price in the timeliest manner is important to your business. We provide microcontrollers, development platforms and free software source code to help you bring a cost-effective design to market in the shortest time possible.
