The Kyma Language for Sound Design, Version 4.5

SpectrumFrequencyScale
Spectral Modifiers Category
Takes a spectral source (which must be harmonic) as its input and scales the frequency envelopes
without changing the amplitude envelopes. This allows you to shift the pitch of the resynthesis, while
leaving the formants at their original frequencies. The SpectrumFrequencyScale should be fed to an
OscillatorBank in order to resynthesize the newly scaled spectrum.
Spectrum
Should be a Sound from the spectral sources category of the Prototypes (based on an harmonic
analysis).
Scale
All frequencies in the spectrum will be multiplied by this scale factor. For example, use 2 to scale up by
one octave, 1 for no change, 0.5 for down by one octave. You can get other intervals by using a ratio of
two pitches that have been converted to hertz. For example, to get a half step up, you could use
4 c sharp hz / 4 c hz
or to shift down by a perfect fifth, you could use
4 c hz / 4 g hz
To control the pitch from the MIDI keyboard, use the ratio of !Pitch to the original pitch of the recording.
For example, if the original recording is a 3rd octave b, you could use
!Pitch hz / 3 b
