Probabilistic Audio Dice Roll
Radioactive decay can only be described using probability; we can never predict exactly when the next event will happen. This uncertainty is inherent in quantum mechanics. Since the time of any given decay is random, then the interval between 2 consecutive decays is also random. I measure two pairs of these intervals, and populate the sequence of bits based on the relative length of the two intervals. This sequence of bits – in decimal representing a number between 0 and 8192 – is used to control the dice throwing. One part of the sequence controls the pitch of the sound. A second part controls the duration of the sound. The count of on-bits versus off-bits in controls whether the audio is triggered or not.
A previous version was part of the "Random Numbers, Tokyo" show.
