MPEG1

The MPEG1 Audio Encode-Decode Software solution is implemented on a single Analog Devices ADSP- 2181 Digital Signal Processor The three sampling frequencies - 3 Audio standards - 44.1 KHz, 48 Khz and 32 KHz are supported. Layer I and Layer II as well as the fixed bit rates and modes have been implemented. It performs compression/ decompression of audio in real time.

The MPEG1 Encode program accepts PCM audio in a memory buffer and generates the compressed data stream in another buffer. Similarly the MPEG 1 Audio Decode program accepts compressed data in a memory buffer and generates PCM audio in another buffer.

The software MPEG1 is available in a library form and OEM users can integrate the solution with their code very easily.
