Follow the below steps for instruction on how to test Full Duplex

1 In Windows 95 / Windows 98, open a copy of Windows Sound Recorder, which is located in the Start Menu under Programs / Accessories / Multimedia If you are running a later version of Microsoft Windows this may be under Programs / Accessories / Entertainment

2 Open a second instance of Sound Recorder

3 Bring up a wav file to play The wav file must be at the same frequency as the one you are about to record To check the frequency, go to File, Properties of the Sound Recorder The frequency will be listed next to 'Audio format' If the wave file plays while you record your full-duplex drivers are installed properly

If you are running a different operating system, similar steps to the above can be performed Open multiple instances of a sound recorder within your operating system and attempt to play and record a sound file at the same time
