Here is a nifty tool that you normally wouldn’t just think of.
You know of those programs that convert powerpoints into flash files so their portable anywhere? Well, heres a program that converts audio and video to an executable that will work on any pc, sadly, mac is not supported.
There is a PRO version, that lets you set bitrates, etc, the free version uses a default bitrate which is likely lower quality. However, for normal applications, a quick conversion, this is a nice little addition to the already quite large toolbox 😛
