MultiplexorSmoothedFract32

Discussion

THIS MODULE IS DEPRECATED AND NOT RECOMMENDED FOR NEW DESIGNS. PLEASE USE THE MultiplexorV2Fract32 MODULE INSTEAD.

This module has a variable number of input pins and routes (or copies) one of these pins to the output. Each input pin must have the same number of channels and block size. The parameter index specifies which of the input pins to route to the output. index is zero based and must lie in the range [0 NUMINPIN-1] where NUMINPIN is the number of input pins. If index is outside of the allowable range, it is clipped so that it lies in the proper range.

Note that this module has built in smoothing to prevent audible clicks. Use the multiplexor_module.m if you do not need smoothing.

Matlab Usage

File Name: multiplexor_smoothed_fract32_module.m 
 M=multiplexor_smoothed_fract32_module(NAME, NUMINPIN) 
 Creates a multiplexor module for using in the Audio Weaver.  The 
 module has multiple input pins and routes 1 of the inputs to the 
 output.  Arguments: 
    NAME - name of the module. 
    NUMINPIN - number of input pins. 

 All input pins must have the same block size and number of channels. 

 Note, this version has built in smoothing with a progammable smoothing 
 time.  If you do not need smoothing, use multiplexor_module.m instead 
 which leads to a more efficient implementation.
