SoundTap is streaming audio capture software which will convert any audio playing through your computer to mp3 or wav files. The high definition audio files can be saved and played back on any device.
If you are interested in testing this for your court, you can download the trial version to test it: https://www.nch.com.au/soundtap/index.html
If something the court can use, request license from Martin Huynh. Note: This software should not be loaded on everyone's computer.
Your court can use FTR if already set up to do so. However it may only work in the physical courtroom, not the virtual court room. Check with Martin Huynh to verify it is setup properly.
