A new function to do this while recording is running. The full voice
playback just can't be made avaiable and to try to use it while recording
would actually be somewhat hazardous and greatly increase the chance of lost
data (all the extra load). The primary goal of recording is to do whatever
possible to make sure the data gets saved. When a built in voice codec is
avaiable it may be more feasable to actually voice the recording screen on
some targets since the load of swapping codecs won't be there. Right now,
only one at a time is actually ready to run, the other is swapped into a
temp buffer. Some other targets will need full duplex sound implemented if
it's even possible to do on them. If not, they'll still need to settle for a
hardware beep.

It should be an especially easy if the hardware has some means of beeping
(using the iPod piezo, I think some others) and how to use it can be figured
out. X5, H100, H300, c200, e200 would need some small software support to
send PCM out while recording.
