Thank you for your comments and taking the time to respond.
Latency is one issue and the other is the internal noise generated by the computer. I find it impossible to record directly through the soundcard for any sort of decent sound. To overcome that I chose to record the voice off line. Th Zoom H2 does a fine job of recording and the sound booth kills any significant unwanted noise. What I find a bit of a challenge at present is finding the right balance between the voice track and the music track. MAybe that is where Reaper will come in handy?
