Free MP4 to MP3 and M4A to MP3

http://www.maniactools.com/es/soft/converter/?ref=m4a-acs


I'm just converting an MP4 video file to MP3 file. So it should be extracting audio from the video mp4 file to an mp3 file :-)

Software i'm using is called Free M4a to MP3 Converter 9.3.

I'm going to confirm what i've just said by opening output folder and check mp3 file :-)
Perfect, i just converter 529 MB of video to 476 MB of audio. Free M4a to MP3 Converter 9.3 works fine with MP4 and extract audio from video file :-)

As you see fomr screenshot, Maniactools offers several Free or Adware Tools with the possibility of disabling ads by supporting developpers :-)
