tanh — Performs a hyperbolic tangent function.


Returns the hyperbolic tangent of x (x in radians).


tanh(x) (no rate restriction)


Here is an example of the tanh opcode. It uses the file tanh.csd.

Example 797. Example of the tanh opcode.

See the sections Real-time Audio and Command Line Flags for more information on using command line flags.

; Initialize the global variables.
sr = 44100
kr = 4410
ksmps = 10
nchnls = 1

; Instrument #1.
instr 1
  irad = 1
  i1 = tanh(irad)

  print i1


; Play Instrument #1 for one second.
i 1 0 1


Its output should include a line like this:

instr 1:  i1 = 0.762
