timek

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

Syntax

ires timek
kres 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 file timek.csd.

Example of the timek opcode.

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
