What other ways of sonifying the heart data can you think of? For
example, you could capture the difference between two values and
use it as note duration. (Hint: Remember to take the absolute value
of the difference, i.e., use function abs(), since the difference may be
negative.) In such a sonification, the duration of the note signifies
the change in heart contraction between two consecutive measurements. Since these measurements are equally spaced in time, the longer the note, the more work was exerted by the heart (during those
two measurements). This is a useful pattern, which is currently lost
in a sea of data. What other useful patterns can you think of?
