Detailed Description

Reads from a table at a variable delay rate.

This is our variable delay class. You can use any signal to control the delay time, or you can just use a number. This particular delay uses four point polynomial interpolation which removes those pesky artefacts.

This class also has a delayRead() function, comparable to the delread~ object. Check the caution warning.

Member Function Documentation

double pd::VariableDelay::delayRead

(

double

delayTime

)

Caution: Do not use this function with the perform() function. Use one or the other. This function reads from the delay line without the interpolation. If you were to use this function and the perform() function you risk both accessing the same address in memory at the same time. If you must do this then I recommend using a mutex.
