Work with octaves

Description

Maintainer : olexandr543@yahoo.com

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.

Synopsis

octaveUp :: Float -> Float
octaveDown :: Float -> Float
liftInOctave :: Int -> Float -> Maybe Float
liftInOctaveV :: Int -> Vector Float -> Vector Float

Work with octaves

octaveUp :: Float -> Float Source #

Returns an analogous note in the higher octave (its frequency in Hz).

octaveDown :: Float -> Float Source #

Returns an analogous note in the lower octave (its frequency in Hz).

liftInOctave :: Int -> Float -> Maybe Float Source #

Function lifts the given frequency to the given number of the octave (in American notation, from 0 to 8). This number is an Int parameter. The function also takes into account the lower pure quint for the closest note. If it is not practical to determine the number, then the function returns Nothing.

liftInOctaveV :: Int -> Vector Float -> Vector Float Source #

Function lifts the Vector of Float representing frequencies to the given octave with the Int number. Better to use numbers in the range [1..8]. The function also takes into account the lower pure quint for the obtained note behaviour. If it is not practical to determine the octave, the resulting frequency is omitted from the resulting Vector.
