MPEG-1 Audio Layer 1 (MP1) is an earlier, simpler version of the MPEG audio standard. MP1 is mostly obsolete, but still supported. MP1 was part of the Digital Compact Cassette format. Almost all files that were MP1 were replaced by the newer MPEG-1 Audio Layer II (MP2) and MPEG-1 Audio Layer III or MPEG-2 Audio Layer III (MP3) file formats.
Due to MP1 being largely obsolete, VLC media player is the best option for opening an MP1 file, with the bonus that this player works across platforms.
Initial Release: 1993
MPEG 4 Audio (M4A) compresses and encodes audio files by using one of two coder-decoder algorithms: Advanced Audio Coding (AAC) or Apple Lossless Audio Codec (ALAC). M4A files are smaller in size while simultaneously better in quality than MP3 files, with which it shares the most similarities, in comparison to all other audio file formats.
M4A files open in most well-known, audio-playback programs, including iTunes, QuickTime, and Windows Media Player. For Apple users, iTunes is the default program to open M4A files. For Windows users, the default program is Windows Media Player. Users can also preview M4A files by highlighting the file and pressing the spacebar.
