I recently had to have a 24hour blood pressure monitor, (everything is fine).
I ended up with 24 hours of data consisting of Systolic and Diastolic pressure as well as heart rate. The machine took these readings every 20 minutes for 24 hours (with a longer interval at night time).
This is a mapping of this into audio for 2.5 cycles of the data
Systolic and Diastolic pressures are mapped directly onto pitch and the heart rate is mapped onto tempo (using audiomulch). After one cycle of 24 hours there are harmonics added into the sound so that the sound becomes more complex.
The graph is of these two figures starting at 9:30 am
Its quite a long piece (32 minutes)
