/* expr.s */ /********************************************************************** expr() *********************************************************************** Function evaluates all its input samples through an expression specified as a parameter to yield an output sample; the number of input buffers is arbitrary and determined at run time. The number of output buffers is also arbitrary (auto-fanout). In the expression refer to the sample on input buffer 0 as in0, for input buffer 1 as in1 and so on. For example: sin(5*PI*in0/100)*exp(-0.001*in1) Note the PI is predefined. |
