Abstract
A method and apparatus to switch between two audio streams without creating a clicking transient. A first serial audio stream is brought into a serial shift register. A series of samples of that audio stream are multiplied by reducing coefficients until a contribution of the first audio stream reaches zero. Then, a second serial audio stream is brought into the serial shift register. Increasing coefficients are applied to a series of samples until a contribution of the second audio stream is one.
