Dean Extract Audio Out Of Video Files Losslessly And Fast Updated May 16, 2011 - 12:10 by arto65 Extract the Audio Stream from a Video When you want to save the audio stream from a video, there is only one way to do it right: demux. Demuxing means splitting up the different streams from a file. This way, you keep the streams in their original quality and it is very fast (less than a minute for 90 minutes of video). So please, next time you want to save audio from a YouTube video, do not convert it to mp3 or use a website to give you a link. Download the video in the highest quality possible with tools such as Video DownloadHelper, then extract the audio. A very good tool to extract the audio is Pazera Free Audio Extractor http://www.pazera-software.com/products/audio-extractor/ it supports almost every format possible, and it can go through a batch of files with no problem. To demux, choose the "Try extract original audio stream" option from the drop-down list of Output Format. If the audio stream is too big (.wav file for example) or in a format that is not supported by your mp3 player (.ac3...), you can ask Pazera Free Audio Extractor to convert it directly for you.
