times

times — Read absolute time in seconds.

Description

Read absolute time, in seconds, since the start of the performance.

Syntax

ires times
kres times

Performance

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

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

times can also operate 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 times opcode. It uses the file times.csd.

Example 809. Example of the times opcode.

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

<CsoundSynthesizer>
<CsOptions>
; Select audio/midi flags here according to platform
; Audio out   Audio in
-odac           -iadc    ;;;RT audio I/O
; For Non-realtime ouput leave only the line below:
; -o times.wav -W ;;; for file output any platform
</CsOptions>
<CsInstruments>

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

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


</CsInstruments>
<CsScore>

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


</CsScore>
</CsoundSynthesizer>


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
