VMP3 is VINJEY's implementation of MPEG Audio Decoder. MPEG Audio is part of MPEG-1 (11172-3) and MPEG-2 (13818-3) standards from MPEG group. MPEG Audio format defines three different layers (Layer 1, 2 and 3) with MPEG Layer 3 popularly known as MP3. MPEG 2.5 is Fraunhofer's proprietary extension for supporting low sampling rates.
Flowchart:
VMP3 supports decoding MPEG1/2 Layer 1, 2 and 3 bitstreams. VMP3 has been developed from scratch keeping in mind MIPS and Memory requirements of resource constrained embedded solutions. VMP3 fully supports both Low Sampling frequency and Multichannel extensions provided as part of MPEG 2 Standard. VMP3 implementation is fully complainant with conformance specifications specified by ISO.
