Headphones Recommended! Heartbeat for Ten Hours is an actual recording of my heart resulting in astonishingly deep bass (warning). While it sounds huge on headphones or big stereos, it may not be audible on phones, tablets or laptops. It a fun challenge to record and took several attempts to get pleasing results. I had to be in a relaxed state so it was recorded in the middle of the night. Using a professional grade small diaphragm condenser microphone, I laid chest down on a foam mattress sandwiching the mic between my chest and the mattress. The bass - low frequency purity was far better than a stethoscope which I first tried attached to a contact microphone. I also tried lying on a cell phone and it was acceptable but kind of noisy. The proximity effect is in full force in this recording. That is an audio phenomenon in which bass sounds are increased in an order of magnitude when very close to a mic. (Think of a crooner singing up close on a mic). With the mic as close to the heart as possible and the chest cavity acting like a resonator, here are the results. I was able to fall asleep during the recording. It was all good until I started snoring which was removed in the final edit. :) Thanks for listening, Dale
