I have set up an experiment using the voice key as my RT, and I also have it set to record the responses (which is awesome!), but I am wondering when DirectRT begins recording the voice? Is it at the start of each trial that requires the voice response? The reason I am asking is because I am curious if I could extract the RT from the .wav file of the voice? If you need me to clarify, let me know Thanks!
