'''MPEG Audio Layer I''', also known as '''MP1''' (but not to be confused with [[MPEG-1]]), is a compressed audio format. There are two versions of it: '''MPEG-1 Audio Layer I''' and '''MPEG-2 Audio Layer I'''.&lt;br /&gt;
&lt;br /&gt;
It is one of the standards defined in [[MPEG-1]] Part 3 (ISO/IEC 11172-3), and in [[MPEG-2]] Part 3 (ISO/IEC 13818-3).&lt;br /&gt;
