How to record a waveform without microphone?

ruski15

Hi there,

I would like to record the waveform I am generating but without having to record with the microphone but just recording digitally. Is this possible?

Cheers, Here is the code.

Is that the same thing 3 times? If so, please edit them to remove the repetition. You can also edit the original question to remove the code there, seeing as it's unreadable.
