Free HD Video Converter Factory is not so much a free simple video converter as the name implies, but it really is an all-round video processing toolkit integrated with multiple practical features that also enable you to edit and extract audio from MOV files efficiently. Without further ado, let's get started.
Step 1. Run Free HD Video Converter Factory and open "Converter".
Step 2. Click "Add Files" or drag and drop MOV files into the "Converter" interface.
Step 3. Open the full list of 500+ optimized presets on the right side. Select "MP3" profile under "Audio" category to convert MOV to MP3. You're allowed to select any one of a dozen of different audio formats as well to convert MOV to WAV, FLAC, WMA and so forth.
Step 4. Select a destination folder and press "Run" button to extract audio from MOV files.
Optional. Before the conversion, you can also extract audio segments from a full-length MOV video. Simply click on the scissors icon to open the "Trim" window, use the two sliders or enter Start/End time to determine the segments you want, then click the green "Trim" button to split the video into parts. Click OK and hit Run button to extract audio segments from MOV videos.
It would be a pity if you only use VLC as a universal player, as it possesses some hidden features under the hood which you can use every day, and that also include, of course, ripping audio from MOV file.
Step 1. Run VLC, click "Media" menu and select "Convert/Save" option.
Step 2. Click "+ Add" button to add a MOV video. Then click "Convert/Save" button.
Step 3. Select "Audio - MP3", "Audio - FLAC" or "Audio - CD" (WAV format) option in the "Profile" section.
Step 4. Press "Browse" button to choose a destination folder.
Step 5. Finally, click "Start" button to strip audio from MOV in VLC.
You can also turn to some online audio extractors to rip audio from MOV online without any software required if you have a stable Internet connection. Just remember, do not exceed the file limit and be patient for the online processing.
I've listed some representative websites below for your reference. Generally, upload MOV file > select desired audio section > select an audio format > wait for the processing > download the audio file.
