The Kyma Language for Sound Design, Version 4.5

Doppler
Mystery Effect
Imagine a sound source moving towards you. As it gets closer and closer, the delay between when the
sound is produced and when the sound gets to you is getting shorter and shorter. At the moment the
sound source passes directly in front of you, the delay is zero. Then as it recedes from you, the delay
grows longer and longer.
You can model this phenomenon using a variable delay line with an inverted-triangle-shaped function
controlling the length of the delay. In other words, the delay gets shorter and shorter, reaches zero at the
apex of the triangle, and then grows longer and longer again. Try playing moving source to hear this effect.
Finally, try out the Sound called phase Flipper . You may be able to use this effect to bring one sound out
from the background.
