Just for your information,
As i found some issues registering my part, be sure that your microfone works properly.
I had some problems with my IMAC that didn’t record, so i use my other PC computer and finally it took my mic audio as well.
In case you are not listening your voice don’t click “Save”, try to change the hardware (PC, MAC ecc) it is more fast and easy.
Cheers!
