One handy utility that everyone needs nowadays is a software program that can extract audio, sound, or background music from home movies, YouTube videos, or any other video file. In this article, I’m going to give step-by-step instructions on how to use a free program called AoA Audio Extractor. Using this nifty little application, you can extract audio from AVI, MPEG, MPG, FLV, DAT, WMV, MOV, MP4, and 3GP and save them into MP3 format or WAV and AC3 format also!

The program is extremely simply to use with the ability to drag and drop files right onto the interface. AoA Audio Extractor also includes a media player, so you can preview the video files from the program itself, saving you the hassle of making sure it’s the right video by playing it in Windows Media Player, etc. It also allows you to control the audio bit rate, audio sample rate and the channel type (mono or stero) for the output file.

However, one of the nicest features of the program that I really thought was quite useful is the ability to extract audio from only a portion of the video clip, instead of the entire file. This is a very basic editing feature, but it’s really helpful because you don’t have to download any sound editing software if you want only some parts of the audio.

To get started using AoA Audio Extractor, download and install the program. Open the program and click the Add Files button to select the video files. You can add more files if you want and they will be processed in a batch.

The videos will show up in the main window along with basic information such as the Start, End, Source Format, and Output Format. You can change the output format under the Output Options section below the main list. Select a video and click on Movie Clip if you want to extract audio from a specific time segment in the video. Before clicking Start, click on Browse and choose the location for the output MP3 file.

Now, go ahead and click Start and the extraction process will begin. The program is pretty fast, it took only 1 minute to extract audio from a 19 minute video clip.

You should now see your audio file at the location specified! I checked the sound quality between the video and the audio file and they were exactly the same, so you’re not going to lose any quality in the extraction process.

And that’s it! I’m going to be writing another article on how to extract audio from a DVD or VOB file soon, so look for that later! Any questions, post a comment!

    Note I had a bunch of .mov files without video, but AOA Audio Extractor seems to crash on those kinds of files after giving a dialog box message that there appears to be no video in the file.

    Some but not all panels do not properly display unicode or multibyte file names. The CPU usage appears to be very high.

    Can you use this program to extract audio from a Powerpoint Presentation?


  11. Mari said on : May 18th, 2008 at 5:53 pm

    Hmm, I can answer my own question so will post in case anyone else wants to know this

    You CAN extract an audio file from a PP presentation.

    Create a new folder (on your desktop or where ever) Open the existing presentation in Powerpoint then click Save As -> Web Page
    Saving the presentation as an html page will generated the page and a folder. You will find all the presentation’s elements in thefolder,including audio file.

    Glad it worked for you Sarah Jane - I’d been searching a long time too then just stumbled on this! :)

    i added a flv file, it’s said it “fail to open [...]”
    i added a avi file, and it worked


  15. Mari said on : June 21st, 2008 at 9:59 am

    Powerpoint doesn’t support FLV files so if that’s the format your video is in you would need to convert it with conversion software to a format PP reconizes. :)

    i used it to extract sound from my AVI file.. and the results sounded like there were aliens attacking in addition to the regular sound. anyone else get similar problems with sound quality being bad?? not really a warped sound, just the addition of funny noises that weren’t there in the video..


Please post your comments/suggestions!
