Compute the actual amplitude given the target intensity, with a plateau at 1.0 in the middle of the intensity range E.g., for source intensity 0.5 and intensity threshold 0.5, with fadeOutLowerIntensities = true;
- target intensity 0.000 -> amplitude 0.0
- target intensity 0.125 -> amplitude 0.5
- target intensity 0.250 -> amplitude 1.0
- target intensity 0.500 -> amplitude 1.0
- target intensity 0.750 -> amplitude 1.0
- target intensity 0.875 -> amplitude 0.5
- target intensity 1.000 -> amplitude 0.0 E.g., for source intensity 0.5 and intensity threshold 0.5, with fadeOutLowerIntensities = false;
- target intensity 0.000 -> amplitude 0.0
- target intensity 0.125 -> amplitude 0.5
- target intensity 0.250 -> amplitude 1.0
- target intensity 0.500 -> amplitude 1.0
- target intensity 0.750 -> amplitude 1.0
- target intensity 0.875 -> amplitude 1.0
- target intensity 1.000 -> amplitude 1.0
- Parameters
-
| audio | instrument audio from which to get source intensity |
| intensityLayers | if the audio only has one layer, intensity is always 1.0 |
| intensityThreshold | distance between source and target intensity at which the amplitude fades down to 0 |
| fadeOutLowerIntensities | whether to fade out lower intensities when the target is higher than the source |
| intensity | target intensity |
- Returns
- amplitude
