Some time ago a good friend of mine sent me an awesome video in WMV format, featuring one of my favorite bands in concert. I enjoy watching the gig from time to time, but as I mainly listen to music while working on the PC, my music player is minimized most of the time. Therefore, having a video in permanent playback was simply a waste of system resources, not to mention a bit of a distraction.
I started looking for a way to extract the audio of this concert so that I could still enjoy it, but without the video part. After some deceptive apps that seemed perfect at first sight but were then full of limitations, I came across Aoa Audio Extractor: a free, simple tool that, according to the developer’s description, enabled you to “extract audio/sound or background music from video files”.
After installing the program in a few seconds, I loaded the WMV video on its interface, selected the appropriate configuration settings and started the conversion process. I minimized the program, thinking that the audio track in a two-hour video would take forever to be extracted, but the program only needed a few minutes to seamlessly rip the video’s soundtrack and save it to an MP3 file. Now I can enjoy this great concert while writing this, and without having to play the video anymore.
I used Aoa Audio Extractor to convert the audio track in a WMV file to MP3, but there are other possible combinations. The program works also with videos in AVI, MPEG, MPG, FLV, MOV, MP4 and 3GP formats, and can save their soundtracks to WAV and AC3, besides MP3.
