All you need is a free MP3 video converter. You simply have to enter a file name and a folder name (or a subfolder if you're using Windows). Then you'll get a high-quality MP3 audio (just within the limits of the original recording, of course), which can then be played on virtually any media player. It's done both on Windows and macOS (and also for Linux) and absolutely free. All you need is a program which can convert a WAV or AIFF file into a LPCD with as little as 5 minutes of your time.
The free mp3 video converter program I found is called Soft-Fi Video Converter. It's a small program, so it won't take up too much of your time - just a few minutes a day, hopefully more if you're that into things these days. It has a simple interface, so even those who are less computer literate shouldn't have too much trouble figuring out how to work it. I personally use Windows, so I downloaded Soft-Fi Video Converter and it worked flawlessly with both Windows 8.x and Windows Vista. So, in order to get the most out of it, I recommend installing it on a Windows machine.
If you're using a MAC, you can use the free convertor called Conversion Plus, which gives you a great conversion rate. However, it's not going to give you perfect results, even though it's MAC compatible. It does, however, work perfectly with Windows, Linux, and iOS - so if you have one of those operating systems, then this conversion program will work perfectly for you. With the conversion, all you do is select the video file you want converted and hit "start." It's fast and easy, and honestly, if you have the time, it's worth paying the small fee for the Mac version of the free MP3 video downloader to convert your videos.
