Install and reg went fine on windows 8.1 64bit. does what it says, does it decent and quick. most but not all formats supported. Does nothing that the free FormatFactory doesn't do.
thums up for how it works but really... isn't this field oversaturated?

NOT saying there's anything wrong with mov Audio Extractor, there are lots of alternatives. Videohelp.com lists 49 tools in its muxer - demuxer category -- muxer = multiplexer, which mean combining the audio & video, & as you'd guess, demuxers do the reverse. Many [most?] video conversion apps can at least demux, as can simple ffmpeg front ends like the free WinFF. For demuxers [audio extractors] it often boils down to if you like the GUI -- mov Audio Extractor is certainly prettier than WinFF.

Audio conversion is a different animal however, although any differences may only be important if you lean more towards being an audiophile. My biggest quarrel with many conversion tools is that they often add processing without giving you a choice in the matter, e.g. normalization & sometimes compression. Normalization is basically a more complicated way of raising the volume level, but too often IMHO it's set to the highest level possible, with no way to adjust that. If you're just extracting the audio from a music video that's fine -- if you intend to mux [combine] the results with video again that's too loud. Software like Soundforge can also use a more complicated method of normalization that can sound better, if that matters to you.

Audio compression reduces the difference in volume between the loudest & quietest portions of an audio file or track -- expansion does the reverse. If there's a big difference -- a large dynamic range -- it sounds better, but, only at high enough volume levels so you can hear the more quiet stuff. Problem is that often you can't raise the volume levels high enough, either because of where you're listening or because your speakers, headphones, or earbuds aren't up to the task. An awful lot of players, software & hardware, offer different levels of compression on-the-fly, so you can keep the full dynamic range in the audio file, adjusting compression in the player to suit you -- that gives you the flexibility to listen to the audio as intended when you can, or keep the neighbors from calling the cops -- lets you watch the same movie on your tablet or using your home theater setup.

There's another potential problem if/when you convert the audio's sample rate... in a nutshell 48/44.1 = 1.08843537414966. If you zoom in to look at an audio file's waveform, the points where there's actual data don't match up when you compare a file at 48000 Hz with one at 44100 Hz. Usually you can avoid extra quality loss simply by avoiding any sample rate conversion when possible, or halve it when it's not. When you can't, say when you want to take an audio track from a video, which more often is sampled at 48, & put it on an audio CD, where the spec calls for 44.1, using software that can use something called dithering helps. That capability isn't rare, but you do have to look for it.

Finally, the last thing to be aware of when you're working with audio & video is that they use completely different clocks. Hopefully you won't have any problems, but it can help to just be aware of potential issues in case you do. If you take out [demux] the audio that's combined with a video file, & compare it to a pure audio recording, very often they will not match. One way they deal with that is by using the AC3 format with audio packets [think capsules] that may contain a surprising amount of empty space -- like a glass with only a little water in it -- the point being that at the start of each packet the audio's in sync. That sort of thing can sometimes cause timing changes converting &/or trimming, maybe more so with video formats like AVC/H.264, that may not have much timing info to begin with, & is made worse when many apps won't handle what timing info there is correctly.

Tried downloading the recommended alternative Pazera Free Audio Extractor in the given link.

However, during download Google Chrome popped this warning.
"Pazera_Free_Audio_Extractor 2-0.exe is malicious, and Chrome has blocked it."

I do not know if this post will be accepted by the mods, because some other posts, like the one that I attempted to place a few days ago in support of Ashraf , asking him to continue to contribute to this site, are being rejected by the moderator.

Having this put out of the way, and hoping again that this post will be approved, I would like to point out that when I pressed All Free Video Converter button, my chrome browser stopped me in my tracks instantly, alarming me that the site is dangerous.
So be careful, Folks.

Giovanni, welcome back.
I have grown to like your contributions very much, especially after having realized the tremendous effort you put into finding some real gems in freeware.
Keep up the good work.

Cheers,

im
