Part 3. How to Turn MP4 Videos into WAV Audio Using Audacity

Audacity is an open-source audio editor that doubles as a handy tool for extracting audio from video files.

This free MP4 to WAV converter is available for Windows, Mac, Linux, and other platforms.

Audacity requires the FFmpeg library to open and import certain video and audio formats, including MP4, AAC, WMA, and more.

If you haven't Audacity already, download and install it on your computer first. Launch Audacity, then click File > Import > Audio to open your MP4 video. Audacity imports the audio track from your MP4 file. You will see the waveform representation of the audio in the main interface.
