Our little thumper

We rented a doppler device so we could hear our baby's heartbeat at home. It works great! Around 155-160BPM. The device has an audio output jack, which I connected to our computer. I recorded the heartbeat as a .WAV file. You can open it by clicking on this link: http://www.industrialpartstrader.com/heartbeat2.wav (It's about 1MB).
