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.

 

How to open an M4A file?

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.

 

Additionally, M4A opens in VLC media player, Adobe Premiere Pro, Elmedia Player, Winamp, and a host of other programs.

Windows Media Video (WMV) is a common and widely supported video format. It compresses the file size with a codec resulting in an easy-to-manage file that maintains the quality of the video. A digital container format, called Advanced Systems Format (ASF), often encapsulates WMV files.

 

How to open a WMV file?

Most media players can open and read WMV (and ASF) files. The best player for opening a WMV file is Microsoft Windows Media Player. Microsoft developed WMV and ASF, and many videos online today are WMV files. VLC media player is another reliable option, which can play multimedia files across several platforms.

 

WMV is also easy to convert to other video file types. However, keep in mind that the conversion process might cause picture quality to decrease. If a conversion is needed, then HandBrake is a free and open-source tool for converting WMV files.
