Product Description

MP3 Decoder (with Layer 1 & 2 support) is a popular 'lossy' decoder used to greatly reduce audio file sizes, while retaining high levels of audio quality faithful to the original uncompressed version. MP3 decoder (with Layer 1&2 support) supports three layers. MPEG-1/2 audio layer 3(MP3) is one of the most popular in PC and internet applications. MPEG-1/2 audio Layer 2(MP2) is used in TV broadcasting and Video CDs.
