WFGUI by Alex Freed - a small program that can analyse a WAV file (44.1kHz 16bit mono format) recorded from a tape deck and measures Wow&Flutter at either 3kHz or 3.15kHz, in the WRMS or DIN wtd standard. This program is a work in progress and hopefully some additional features and a real-time processing will be added soon.
Note: This software is provided in good faith, but is supplied "as is" without any warranty of any kind.

Real-time frequency counter from William Andrew Steer - very useful for tape deck speed setting!
