SoundConverter is software for batch converting stereo sound files to mono sound format automatically. Simply place the desired options in the dialogue box, click OK and wait for the conversion to finish. You needn't worry about compatibility with other programs as it is a Windows interface only. I am pretty sure there would be one or two operating systems that can run this program flawlessly. I remember that I couldn't even start my computer to try this out, because of its incompatibility.
SoundConverter comes with various options to choose from, so depending upon your requirements you can choose the right one. The best thing about this particular program is that it supports all types of format conversions i.e., Aiff, WAV, MP3 etc. It has also an inbuilt scanner that scans and detects most common audio file formats.

If you plan to use it for regular audio file conversions, you will be able to appreciate its speed and efficiency more.
