Sometimes we want to extract an audio stream from a video file because we only need a soundtrack instead of a large video file. Several websites, applications and browser extensions allow you to extract audio from a video file by converting it to WAV, MP3 or other audio format.
In this article, we will talk about one of the FFMpeg command line based file conversion utilities, with which you can convert mv4 video file to WAV audio format on Linux system. We will also discuss converting files graphically using WinFF, which is actually the interface of the FFMpeg utility. FFmpeg and its WinFF interface are open source applications that make it easy to manipulate and convert video files to other formats.
We used Debian 10 to run the commands and procedures mentioned in this article.
Convert M4V to WAV via command line with FFMpeg
To open a terminal in your Debian OS, go to the Actions tab in the upper left corner of your desktop. Then search for FFMpeg using the search bar that appears. When the terminal icon appears, click on it to open it.
Now, to install FFMpeg, run the following command as sudo in Terminal:
$ sudo apt-get install ffmpeg
When prompted for a password, enter your sudo password.
The system will ask for confirmation, giving you the Y / n option. Press y to continue and the installation of MMPeg will begin on your system.
After installation, you can check the MMPeg version by running the following command in the terminal:
$ ffmpeg --version
To see a list of all formats supported by FFmpeg, run the following command in a terminal:
$ ffmpeg --formats
You can also find a list of supported FFmpeg formats on the FFmpeg official website.
Now the following syntax can be used to convert files using FFmpeg:
$ ffmpeg -i Input_File Output_File
For example, to convert our “wind.m4v” file located in the ~ / Downloads folder to the “wind.wav” format, we used the following command in the terminal:
$ ffmpeg -i ~/Downloads/wind.m4v wind.wav
The above output wind.wav file will be created in our current directory.
To check if the wav file was created successfully, run the ls command in Terminal.
M4v to WAV conversion via GUI with WinFF
To convert Mv4 to wav file format via GUI using WinFF follow this procedure:
WinFF can be installed through the Debian Software Manager. To launch the Software Manager on your Debian system, press the superkey on your keyboard and on the left sidebar, click on the Software Manager icon.
When the Software Manager opens, click on the search button located in the upper right corner of its window. Enter the keyword winff in the search bar. When the search result appears, click on the WinFF utility as shown in the following screenshot.
