Recording for a set period

I beg your patience for I am near an complete illiterate in understanding the terminology being used.

I am importing cassette audio to Audacity so that that I can make CD’s of public audio stuff to give away.
I am trying to import several audios to the same Audacity recording program. I know how to do this. But, I am unable how to
figure out if I can set the Audacity program to record one audio for a set time period in which the recording of the
audio import will begin & then stop after a selected time period by me. In this way I do not have to remain clued to the
computer & can go to do something else. Can someone explain it to an old man in simple terms.

Thank you for your patience.


Thank you kindly, Steve, for responding so quickly to my question.
As you can tell, I am a novice at this. Thank you for your patience.
