Enum FadeCurve 

#[repr(u32)]
pub enum FadeCurve {
    EqualPower3dB = 0,
    EqualPower6dB = 1,
    SquareRoot = 2,
    Linear = 3,
}

The algorithm used to map a normalized crossfade/panning value in the range [-1.0, 1.0] to the corresponding gain values for two inputs.

Variants

EqualPower3dB = 0

This curve makes the combined signal appear to play at a constant volume across the entire fade range for most signals.

More specifically this a circular curve with each input at -3dB at center.

EqualPower6dB = 1

Same as FadeCurve::EqualPower3dB, but each input will be at -6dB at center which may be better for some signals.

SquareRoot = 2

This is cheaper to compute than FadeCurve::EqualPower3dB, but is less accurate in its perception of constant volume.

Linear = 3

The cheapest to compute, but is the least accurate in its perception of constant volume for some signals (though if the signals are highly correlated such as a wet/dry mix, then this mode may actually provide better results.)
