Case studies

Developing an Asynchronous Sample Rate Converter

Designing an Asynchronous Sample Rate converter that offers high THD and low ripple across a range of frequencies is no mean achievement. We not only designed the ASRC but implemented it with low MHz on a fixed point processor.

Android customisation for connected media player

Our customized Android for an MID device for a Top-5 Consumer Electronics company. Key elements of the project included adding MTP, WM-DRM and audio post processing.
