|
| Pitching, Playing and Scratching |
|
| pitchWavSignal :: FilePath -> [Double] -> Signal |
| Open a Wav-File, but play it with variable (positive) speed/ frequency. |
|
| scratchWavSignal :: FilePath -> [Double] -> Signal |
| Open a Wav-File, but play it with variable (positive and/or negative) speed/ frequency.
Backward playing is possible. |
|
| playSample :: Sample a -> [a] |
| Creates a finite list with the content of the Sample. |
|
| pitchSample :: (Fractional a) => Sample a -> [Double] -> [a] |
| Creates a list with the content of the Sample, but played with variable speed/frequency. |
|
| scratchSample :: (Fractional a) => Sample a -> [Double] -> [a] |
| Creates a list with the content of the Sample, but played with variable speed/frequency,
backward playing possible. |
|
| playCoeffs :: Coeffs -> [Complex Double] |
| Creates a list with the content of Coeffs (a representation of the fourier coefficients of
a Sample). |
