For example, you may have both English AC3 and DTS channels, but you may also have other audio streams for other languages, directors comments, etc. It should also be mentioned that your source video file may have multiple audio channels or streams. This very well could have been an AVI, MPEG, or any other video format that FFmpeg can decode.įfmpeg -i video.mkv -acodec pcm_s16le -ac 2 audio.wav Here’s an example of extracting the audio from a video file called video.mkv and saving it to a file called audio.wav. Another method using FFmpeg instead of Mplayer was also pointed out in the post titled Add Stereo Audio Tracks to MKV Files, and I figured it would be useful to outline the quick one-step process in a post all by itself. Previously, I described how to Extract Audio from Video Files to WAV using Mplayer. Posted by admin on Decemunder Tech Tips | Read the First Comment the picture below shows exactly what I have.Extract Audio from Video Files to WAV using FFmpeg When I right click on the file I would like to extract I do not have the 'Extract Audio Sorce' option as in the video. Best part is I already have VLC downloaded. So I went searching for a third party program that could extract the multiple tracks so I could put them in my editing software individually when i came across this. Now I know I could probably just find another open source editing software that supports this, but I've become comfortable with this program already and have begun toning in on really making higher quality videos. The editing software that I'm using does not split the audio. Now I can raise and lower specific tracks as needed. That is until I just recently found out that the recording software I use supports multiple audio tracks. My goal is to create quality videos but for the past week or so audio 'fluctuations' have haunted me. I recently finished building my 'super' computer, and I've started my own YouTube channel.
