## nsamp

nsamp — Returns the number of samples loaded into a stored function table number.

## Description

Returns the number of samples loaded into a stored function table number.

## Syntax

    nsamp(x) (init-rate args only)

## Performance

Returns the number of samples loaded into stored function table number x by GEN01. This is useful when a sample is shorter than the power-of-two function table that holds it. New in Csound version 3.49.

## Examples

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

Example 240. 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
