Examples

Here is an example of the nsamp opcode. It uses the files nsamp.orc, nsamp.sco, and mary.wav.

Example 15-1. Example of the nsamp opcode.

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

; Instrument #1.
instr 1
  ; Print out the size (in samples) of Table #1.
  isz = nsamp(1)
  print isz
endin
/* nsamp.orc */
        
/* nsamp.sco */
; Table #1: Use an audio file.
f 1 0 262144 1 "mary.wav" 0 0 0

; Play Instrument #1 for 1 second.
i 1 0 1
e
/* nsamp.sco */
        
Since the audio file "mary.wav" has 154390 samples, its output should include a line like this:
instr 1:  isz = 154390.000
