Description

The Memory Stick Voice format is an audio file format used for recording on the Sony Memory Stick IC recorder (ICD-MS1). There are two variants of the format - the first is MSV (ADPCM), which apparently uses a special version of ADPCM [1], and the second is MSV (LPEC), using Sony's proprietary LPEC codec.
