title: Octave Shift
description:
The octave shift. This is the octave shift of the source frequency. For example, a shift of +1 would double the frequency; -1 would halve the frequency and 0 would leave the pitch unaffected. To put this in frequency terms, a frequency shift f (where f greater than one for upwards shift and less than one for downwards) is: o = log(f) / log(2). Ignored if pitchscale is set.

title: Pitch Scale
description:
The pitch scaling ratio. This is the ratio of target frequency to source frequency. For example, a ratio of 2.0 would shift up by one octave; 0.5 down by one octave; or 1.0 leave the pitch unaffected. To put this in musical terms, a pitch scaling ratio corresponding to a shift of o octaves (where o is positive for an upwards shift and negative for downwards) is: f = pow(2.0, o). Overrides octaveshift.
