From Within is a project that tries to create music through heartbeats. The program is provided with heartbeat input through a stethoscope, that is connected to a mic input. After setting an amplitude threshold for the input beats, the program then calculates the number of heartbeats per minute. This heartbeat rate is calculated every 5 seconds.

The system is programmed to play a higher or a lower chord, depending on whether the heartbeat rate increases or decreases. This interactive audio program was created using p5.js.
