timek

timek --  Read absolute time in k-rate cycles.

Description

Read absolute time, in k-rate cycles, since the start of the performance.

Syntax

ir timek

kr timek

Performance

timek is for time in k-rate cycles. So with:

  sr    = 44100 
  kr    = 6300 
  ksmps = 7
        

then after half a second, the timek opcode would report 3150. It will always report an integer.

timek can produce a k-rate variable for output. There are no input parameters.

timek can also operate only at the start of the instance of the instrument. It produces an i-rate variable (starting with i or gi) as its output.

Examples

Here is an example of the timek opcode. It uses the files timek.orc and timek.sco.

Example 1. Example of the timek opcode.

/* timek.orc */
; Initialize the global variables.
sr = 44100
kr = 4410
ksmps = 10
nchnls = 1

; Instrument #1.
instr 1
  ; Print out the value from timek every half-second.
  k1 timek
  printks "k1 = %f samples\\n", 0.5, k1
endin
/* timek.orc */
        
/* timek.sco */
; Play Instrument #1 for two seconds.
i 1 0 2
e
/* timek.sco */
        
Its output should include lines like this:
k1 = 1.000000 samples
k1 = 2205.000000 samples
k1 = 4410.000000 samples
k1 = 6615.000000 samples
k1 = 8820.000000 samples
