ExtensionThis is a simulation of the distortion that happens in class B and AB power amps when the signal crosses 0.For class B simulations the smooth value should be set to about 0.3 +/- 0.2 and for AB it should be set to near 1.0.
| in | 
 The input signal.  | 
| amp | 
 Controls the point at which the output signal becomes linear.  | 
| smooth | 
 Controls degree of smoothing of the crossover point.  | 
| mul | 
 Output will be multiplied by this value.  | 
| add | 
 This value will be added to the output.  |
