The review below is worth repeating: "Do NOT, under ANY CIRCUMSTANCES download audacity from Sourceforge!!! They attach all sorts of malware to the download. YOU WILL INFECT YOUR COMPUTER!!!! Instead, go to the REAL audacity site: www.audacityteam.org " I spent half the night removing the large suite of nasty (and some very nasty) malware that embedded themselves deep within Windows and hijacked all browsers to the point of crippling them (with those false pop-up warnings that would not go away simply by clicking an 'x' - and I'm an electronics tech with a former computer tech cert - if you are not, then your computer is screwed. If you do not know how to quickly remove malware (including the nastiest), then don't download from this site - use the original site. Just a note - after I removed all the malware, I took a chance and manually installed the 'free' Audacity (worst case - all the malware would reinstall) - it installed OK - without the malware. I haven't tried Audacity yet - so I'm not sure if it will meet my needs, not knowing what functions and features it has - so my one-star review is a warning about this site...
You may try use Avdshare Video Converter to Convert MP4 to Windows Media Player more compatilbe video format like convert MP4 to WMV, MP4 to AVI, MP4 to MPG, MP4 to ASF.
I have used this since high school. Still super simple and easy to use.
Beyond useless. My primary reason for using this program was to make ringtones and samples. However, after it resetting my time selections randomly over a dozen times in one day, I'm done. This program is no longer usable. I'll just pirate goldwave instead, hopefully by the next time I check in this will be fixed, finally.
