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.
Audio file created by Audacity, a free, cross platform audio editor; uses a proprietary format that can only be opened by Audacity; saved as one of multiple audio data files for an Audacity project (.AUD).
