playing and recording at the same time

[Claire Bradin Siskin]

We are working on a research project in Rev in which students hear a 
prompt and immediately repeat what they hear. (The process is similar 
to simultaneous translation in which the translator speaks while the 
speaker continues to speak.) Playing the sound and recording must 
happen at the same time.  We want to record the prompt and the 
student's response all in one file.

We have have been able to record these in one file with a poor 
quality version of the prompt (coming from an external speaker) and a 
good quality response using an external microphone. We are surmising 
that the prompt is being picked up by the mic which accounts for the 
poor quality. For the project we will have to use headsets (mic and 
headphone combined) which would prevent the prompt from being picked 
up by the microphone, so we need a better solution.

Can we set the recording to stereo and use one track for the internal 
sound and the other for the microphone input? Or can anyone suggest 
another method to accomplish this task?

Thanks, Claire
