How to Convert MP4 to Wav Files

Video files come in many formats including MP4. The MP4 video format is based on Apples MOV video format. This video format contains a separate video and audio stream which can be converted to other types of files such as WAV. WAV is a Microsoft and IBM audio file format which is used on Windows computer systems for uncompressed audio. An MP4 file can be converted to an WAV file by following a few steps to extract the audio stream.
