#recording inputs are displayed, check boxes for which ones will be recorded, timestamped wavs recorded to same directory, close app to finish recording.
#haven't implemented the monitoring things that are reflected on the UI yet... although it isn't really necessary
#if you go into the windows audio control panel there is an checkbox to toggle to monitor called "listen to this device"
#compared to the earlier version the difference in behavior is that this supports up to 11 inputs and doesn't record anything for unchecked inputs.
