Composition.Sound.Functional.Split

Helps to create experimental music from a file (or its part) and a Ukrainian text. It can also generate a timbre for the notes. Uses SoX inside.

Splitting and concatenating OvertonesO

splitO :: Int -> OvertonesO -> [OvertonesO]

Splits (with addition of the new overtones) a given OvertonesO into a number n (specified by the first Int argument) of OvertonesO (represented finally as a list of them respectively) so that all except the first n greatest by the absolute value of the amplitude tuples of Floats are considered overtones for the greatest by the absolute value one in the given OvertonesO and all the next n - 1 are treated as the greatest by the absolute value and each of them produces the similar by the f :: Float -> OvertonesO function overtones.

It is expected to obtain by such a conversion a splitted one sound into several simultaneous similar ones with different heights. To provide a rich result, the given first argument must be strictly less than the length of the given OvertonesO minus one.

splitO2 :: (OvertonesO -> OvertonesO) -> Int -> OvertonesO -> [OvertonesO]

Splits (with addition of the new overtones) a given OvertonesO into a number of OvertonesO (represented finally as a Array Int of them repsectively) so that it intermediately uses a special function before applying the "similarization" splitting function. Is a generalization of the splitO, which can be considered a splitO2 with a first command line argument equals to id.

It is expected to obtain by such a conversion a splitted one sound into several simultaneous similar (less or more, depending on h :: OvertonesO -> OvertonesO) ones with different heights. To provide a rich result, the given first argument must be strictly less than the length of the given OvertonesO minus one.

overConcat :: [OvertonesO] -> OvertonesO

Concatenates a list of OvertonesO into a single OvertonesO. Can be easily used with splitO.

Generalization of the previous ones splitting functions

splitHelp1 :: Int -> Int -> Int -> Int -> [(Float, Float)] -> (Float, Float) -> [OvertonesO]

Auxiliary function that is used inside splitOG1.

splitHelp2 :: (OvertonesO -> OvertonesO) -> Int -> Int -> Int -> Int -> [(Float, Float)] -> (Float, Float) -> [OvertonesO]

Auxiliary function that is used inside splitOG2.

splitOG1 :: String -> Int -> OvertonesO -> [OvertonesO]

Generalized variant of the splitO with the different splitting variants depending on the first two ASCII lower case letters in the String argument.

splitOG2 :: (OvertonesO -> OvertonesO) -> String -> Int -> [(Float, Float)] -> [OvertonesO]

Generalized variant of the splitO2 with the different splitting variants depending on the first two ASCII lower case letters in the String argument.

splitOG12 :: (Int, Int, Int, Int) -> [(String, Int -> [(Float, Float)] -> (Int, Int, Int, Int))] -> String -> Int -> [(Float, Float)] -> [OvertonesO]

Generalized variant of the splitOG1 with a possibility to specify a default value for splitting parameters as the first argument (Int,Int,Int,Int) and the sorted by the first element in the tuple (actually a String) in ascending order list (the second one). Each String in the list must be unique and consist of lowercase ASCII letters.

splitOG12S :: (Int, Int, Int, Int) -> [(String, Int -> [(Float, Float)] -> (Int, Int, Int, Int))] -> String -> Int -> [(Float, Float)] -> [OvertonesO]

Variant of the splitOG12 applied to the unsorted second argument. It sorts it internally. If you specify the already sorted second argument then it is better to use splitOG12. Each String in the list must be unique and consist of lowercase ASCII letters.

splitOG22 :: (Int, Int, Int, Int) -> [(String, Int -> [(Float, Float)] -> (Int, Int, Int, Int))] -> (OvertonesO -> OvertonesO) -> String -> Int -> [(Float, Float)] -> [OvertonesO]

Generalized variant of the splitOG2 with a possibility to specify a default value for splitting parameters as the first argument (Int,Int,Int,Int) and the sorted by the first element in the tuple (actually a String) in ascending order list (the second one). Each String in the list must be unique and consist of lowercase ASCII letters.

splitOG22S :: (Int, Int, Int, Int) -> [(String, Int -> [(Float, Float)] -> (Int, Int, Int, Int))] -> (OvertonesO -> OvertonesO) -> String -> Int -> [(Float, Float)] -> [OvertonesO]

Variant of the splitOG22 applied to the unsorted second argument. It sorts it internally. If you specify the already sorted second argument then it is better to use splitOG22. Each String in the list must be unique and consist of lowercase ASCII letters.
