timeinsts — Read absolute time in seconds.


Read absolute time, in seconds, since the start of an instance of an instrument.


kres timeinsts


Time in seconds is available with timeinsts. This would return 0.5 after half a second.

timeinsts produces a k-rate variable for output. There are no input parameters.

timeinsts is similar to times except it returns the time since the start of this instance of the instrument.


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

Example 460. Example of the timeinsts opcode.

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

; For Non-realtime ouput leave only the line below:
; -o timeinsts.wav -W ;;; for file output any platform

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

; Instrument #1.
instr 1
  ; Print out the value from timeinsts every half-second.
  k1 timeinsts
  printks "k1 = %f seconds\\n", 0.5, k1


; Play Instrument #1 for two seconds.
i 1 0 2


Its output should include lines like this:

k1 = 0.000227 seconds
k1 = 0.500000 seconds
k1 = 1.000000 seconds
k1 = 1.500000 seconds
k1 = 2.000000 seconds
