Some Wikipedia articles include
files, that can be played on almost all personal computers. However, your computer must have the right software. If your computer does not automatically play these files when you click on them, downloading and installing free software from the Internet can enable it to do so.
Sound files on Wikipedia generally use the
audio format, and video files use the
format, both contained in either
, and older
do not support these formats by default, and depend on software to play the files. When you use Wikipedia in a browser this software is integrated by default.
Music files may occasionally use the
format (.MID or .MIDI extension). Wikipedia can play a MIDI file by converting it to digital audio, or depending on how the MIDI file is linked it may rely on your computer's browser and hardware to play the MIDI file.
For help making and converting video and audio into the format usable on Wikipedia, see
