New function: GEN-ENVELOPE-TENDENCY This function takes a list of data and adjusts the values to fit within the specified lower and upper envelope limits. If a value is outside the given envelope, the function will adjust it to fit within the envelope and all subsequent values in the list are also adjusted by the same amount, which helps to preserve the original shape of the data. Examples: (setf data (gen-brownian-motion 128 :seed 43)) (setf len (length data)) (setf l-limit (envelope-samples '(0 0 1 -1 2 -1 3 -2 4 3 5 -1 6 0) len)) (setf u-limit (envelope-samp…

ver. 3.0.28933 New functions: Probability->Distribution BETA-DISTRIBUTION The function returns a list of values generated from the Beta distribution using the given alpha and beta parameters. The Beta distribution is a continuous probability distribution defined on the interval [0, 1]. It is commonly used to model random variables that have values between zero and one, such as proportions, probabilities, or parameters that are constrained to a specific range. BILATERAL-EXPONENTIAL The bilateral exponential distribution is a probability distribution that models random variab…

I quickly change the names of the 2 new functions: FTT-W -> FTTW FTT-H -> FTTH I too added few more options into the FFTW function: coefficients and scale-factor Please make change to your code if you are already played with the FFT functions. Best wishes, Janusz

New function: FFTH, FFTW Brownian motion functions are rewritten. If you used them before please check the documents. Improvement to probability functions. FFTH num-of-harmonics step-resolution points &key type quantize coeff ambitus The function FFTH calculates the Fast Fourier Transform (FFT) of a given list of points. The FFT is a mathematical algorithm that transforms a function of time (a signal) into a function of frequency. In the context of digital signal processing, the FFT algorithm is used to identify the frequencies present in a discrete signal. The computation involves the following steps: Initialization: Arra…

New function in 3.0.28902 rhythm-series num number-of-notes span &key length prob seed This function returns a list of successive rhythmic series derived from a span (overall duration), length values, and a number of length-notes per bar. The length- notes within each bar are positioned at random. Simple examples: (rhythm-series 4 3 3/8) => ((-1/16 1/8 -1/16 1/16 1/16) (1/16 3/16 1/8) (1/8 3/16 1/16) (3/16 1/16 1/8)) (rhythm-series 4 5 3/8)…
