Product Details

MP3 is a widely used compression technology that provides CD quality audio at significantly lower bit rates than the original CD data rate. The ADI MP3 encoder is a high performance encoder that is capable of delivering high quality compressed audio at fast encoding speeds – over 12x real-time encoding can be achieved on a 600MHz Blackfin processor.

The ADI MP3 encoder has been highly optimized to run on the Analog Devices' Blackfin processor family. It is a self-contained software module that produces fully compliant ISO/IEC 11172-3 MPEG-1 audio specification and rigorously tested and field-proven in commercial application.
