Advanced Systems Format (ASF) is a proprietary Microsoft product, which serves as a container for Windows multimedia content. Microsoft designed it for streaming and to be independent of systems and protocols. It supports chapters, captions, subtitles, metadata tags, streaming, and hardware players, but does not support menus.
It is best to use Windows Media Player to open an ASF file. Alternatively, VLC media player is a good choice too. Keep in mind that ASF can contain WMA and WMV files, which might display as the file extension of the ASF file.

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.
