- Description
- MPEG-1 Audio Layer I, commonly abbreviated to MP1, is one of three audio formats included in the MPEG-1 standard. It is a deliberately simplified version of MPEG-1 Audio Layer II (MP2), created for applications where lower compression efficiency could be tolerated in return for a less complex algorithm that could be executed with simpler hardware requirements. While supported by most media players, the codec is considered largely obsolete, and replaced by MP2 or MP3.
- A WMV file is a video file based on the Microsoft Advanced Systems Format (ASF) container format and compressed with Windows Media compression. It contains video encoded with one of Microsoft's Windows Media Video (WMV) proprietary codecs and is similar to an .ASF file.
