Pitching, Playing and Scratching

pitchWavSignal :: FilePath -> [Double] -> Signal Source

Open a Wav-File, but play it with variable (positive) speed/ frequency.

scratchWavSignal :: FilePath -> [Double] -> Signal Source

Open a Wav-File, but play it with variable (positive and/or negative) speed/ frequency. Backward playing is possible.
