When working with Lync and Exchange I regularly find myself needing to convert MP3 files to WAV files for the specific need of UM.  Typically, this involves finding the right bit rate, etc.  After finding a command line tool (SoundeXchange) to do this, I naturally wanted it even easier so I created a function in PowerShell to do just that.

In order to run this script, you do need a few pre-reqs.  First, you need to install SoundeXchange.  You can download it from here: http://sox.sourceforge.net.  My script is based on version 14.4.0 and I believe there is a newer version out so change the script below to fit the version you install.
