Like the infinite monkeys typing Shakespeare, but with audio instead.
If there was a program that created a series of sounds at random intervals, pitches, amplitudes, etc., how long would it take to produce an output that sounds like music, some sort of recognisable recording (e.g. a bell ring, a dog barking), or perhaps even a human voice?
Well let’s assume there’s a functionally infinite number of sounds and a functionally infinite variety of songs and voices. The set of songs and voices is a smaller infinite set than the set of all sounds. That would make the odds per generation effectively n/∞. So essentially zero.
