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

Example 1. Example of the filesr opcode.

/* filesr.orc */
/* Written by Kevin Conder */
; Initialize the global variables.
sr = 44100
kr = 4410
ksmps = 10
nchnls = 1

; Instrument #1.
instr 1
  ; Print out the sampling rate of the 
  ; audio file "mary.wav".
  isr filesr "mary.wav"
  print isr
endin
/* filesr.orc */
        
/* filesr.sco */
/* Written by Kevin Conder */
; Play Instrument #1 for 1 second.
i 1 0 1
e
/* filesr.sco */
        
The audio file "mary.wav" was sampled at 44.1 KHz. So filesr's output should include a line like this:
instr 1:  isr = 44100.000
