If the computer's sound device provides an input for recording computer playback, you are able to record and listen at the same time. This depends entirely on the drivers of your sound device. It could be called Stereo Mix, Wave Out, Sum, What U Hear, Loopback or another name. In the steps below, we are assuming that your driver is named Stereo Mix.
