RhythmicCellularAutomaton Scripts Category This Sound is based on the one-dimensional cellular automata described by Stephen Wolfram in his book "Theory and Applications of Cellular Automata". The state, an n-place binary number, where n is the number of Inputs, determines when the Input is turned on and when it is turned off in a given generation. An integer, rule, is used to determine the next state. This differs from the CellularAutomaton in that the state is interpreted "horizontally" (rhythmically) rather than "vertically" (harmonically). Each generation of the automaton is interpreted as a rhythmic pattern, where a 1 means the Input is turned on, and a 0 means the Input is turned off (for the duration of the Input). Input This Sound is repeated in a pattern determined by the state of the automaton in each generation. When a value in the state array is 1, the Sound is played, and when a value in the state array is 0, there is a silence of the same duration as the Sound. This field accepts only one Sound at a time. Rule If you look at the rule and the state as 8-bit binary numbers, you can use the rule to compute the next generation of the state. Number the positions of the digits 0 to 7 counting from right to left. To compute the next generation of position P of the state: Take the number at position P, P+1 and P-1 (i.e. the number at position P and its neighbors to the right and to the left). Think of this as a three digit binary number N that you are going to use as an index into the binary number representing the rule. Look at position N of the rule. The value at position N of the rule is the value of position P in the next generation of the state. For example, if the rule is 2r10101110 and the state is 2r10010101, let’s compute the next generation state of position 3. The current value at position 3 of the state is ’0’. Looking at position 3 and its two neighbors as a binary number, we get ’101’ or the number 5. Using this number as an index, look at position 5 of the rule; it is ’1’. So the value of position three in the next generation is ’1’. When you reach the rightmost or leftmost digit in the state, make the assumption that there is an infinite number of zeroes extending both leftwards and rightwards. Generations This is the number of generations. InitialState Imagine the initial state as an n-bit binary number where n is the size of the collection of Inputs. Each digit in the binary number corresponds to a Sound in the Input collection; use a 1 to indicate that a Sound is initiallly on, a 0 to indicate that it is initially off. GenerationLength This is the number of bits in each generation. 330
RMSSquared Tracking Live Input Category This can be used to get an estimate of the amplitude envelope of the Input. The output is input^2 * timeConst + prev * (1 - timeConst) This is the root mean square of the input without the final square root at the end. Input This is the Sound whose amplitude is tracked. TimeConstant This controls the response time. Longer timeConstants result in smoother outputs at a cost of losing some of the detail in the attacks. Short timeConstants result in outputs that respond more immediately to attack transients but that may not be as smooth for the steady state portions. For a constant input at maximum amplitude, this is the time required for the output to reach 60% of the full output amplitude. (Note that the output may never reach the maximum possible amplitude since it is the average of the squares of the amplitudes). Scale Attenuates the input amplitude. 331
