In the last few hours I have become increasingly interested in waveform permutations based on low bit resolution and low sample rate constraints - to be more specific, I have become interested in hearing all of the permutations of a given set.
So let's get the ball rolling.
I have named my first example (2 ^ 1) ^ (2 ^ 4). That is because this is the total number of waveforms present in this set. This particular set is defined as being 1 bit in depth (hence the "2 ^ 1") and has a waveform length of 16 (hence the "2 ^ 4").
In other words, it is a sonification of all possible 16-bit words(from 0x0000 to 0xFFFF) when represented as a continuous 1-bit waveform. Each waveform is only played once - ie. each 16-bit long number is not repeated.
Personally, I find the resulting audio output almost hypnotising but I am sure others will disagree.
I have realised this outcome on a Sega Master System II console. The audio that you can download below was recorded directly from hardware.
