Can Audacity extract audio from video? When you search for a free tool to edit audio, you may easily get the Audacity recommendation. It is a powerful, open-source audio software for editing, recording, and converting sounds. However, when it comes to extracting audio from video in Audacity, a question arises: The software fails to open your MP4/MOV file, or displays an error message. You may be confused if Audacity is able to separate audio from a video.

As mentioned above, when you try loading a video file in Audacity, you often fail to do that. This is a common issue for many new users.
The truth is, Audacity is a dedicated audio tool that does not support video files by default. It lacks the necessary code to decode video files like MP4, MOV, MKV, or AVI. But you can unlock its capability with a little help. You can install a plugin called FFmpeg Import/Export Library to bridge this gap. Then, Audacity will let you add video files and work with their audio tracks.
This optional plugin enables Audacity to read the container format of a video and access the audio stream inside. After installation, you can directly access the video’s audio track and import it into Audacity for editing and exporting.
You can install the FFmpeg Import/Export Library to unlock video imports. Besides, it will support more audio formats, including WMA, M4A, and AC3.
Whether you use Audacity on a Windows PC or Mac, you can download the FFmpeg Installer from /lame.buanzo.org/ffmpeg.php. Select the correct version based on your system version.
Open the downloaded file to turn the installer. When the installation is complete, close and reopen Audacity. The software will automatically detect the FFmpeg Library.
As you can see from the FFmpeg for Audacity page, you need to manually customize the installation if you have installed FFmpeg from a different source. Go to the Preferences of Audacity, click Libraries, and then click the Locate... button.
With FFmpeg installed, you can handily extract audio from a video with Audacity. As mentioned, you should restart the software after the FFmpeg Library installation.
Sometimes, you will be prompted to select stream(s). Then, you will see the importing process. Audacity will not load the video file. Instead, you will see the waveform of its audio track appear in the main editing window.
If you are not comfortable with the separate FFmpeg installation or unsatisfied with the whole audio extraction process, you can turn to a great Audacity alternative, Aiseesoft Video Converter Ultimate, for a more streamlined experience.
