Standard linear crossfader with two inputs, used to mix between 2 audio (or control) signals with an adjustable transition.
Audio/Control Input A
Audio/Control line to use when Alpha is towards 0.
Audio/Control Input B
Audio/Control line to use when Alpha is towards 1.
Control input to automate the Alpha setting, from 0 to 1.
This input can be toggled from the Node settings panel.
Sets the crossfader “position”. Values towards 0 put more of A into the mix, values towards 1 more of B.
Sets the crossfade effect to use.
- Gain crossfade: use gain-wise linear crossfade between A and B.
- Filter crossfade: use low-pass filter on A and high-pass filter on B with the same frequency.
The mixed audio/control inputs.
When Fade mode is gain, this node performs a per sample linear interpolation:
A * (1 - alpha) + B * alpha.
When Fade mode is filter, a center frequency between 10 Hz and 22 kHz, based on the alpha setting is determined. A low-pass filter with this frequency is used on A, and a high-pass filter with the same frequency on B.
