## ftlptim

ftlptim — Returns the loop segment start-time of a stored function table number.

## Description

Returns the loop segment start-time of a stored function table number.

## Syntax

    ftlptim(x) (init-rate args only)

## Performance

Returns the loop segment start-time (in seconds) of stored function table number x. This reports the duration of the direct recorded attack and decay parts of a sound sample, prior to its looped segment. Returns zero (and a warning message) if the sample does not contain loop points.

## Examples

Here is an example of the ftlptim opcode. It uses the file ftlptim.csd, and mary.wav.

Example 213. Example of the ftlptim opcode.

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

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

    ; Instrument #1.
    instr 1
      ; Print out the loop-segment start time in Table #1.
      itim = ftlptim(1)
      print itim
    endin

    </CsInstruments>
    <CsScore>

    ; Table #1: Use an audio file, Csound will determine its size.
    f 1 0 0 1 "mary.wav" 0 0 0

    ; Play Instrument #1 for 1 second.
    i 1 0 1
    e

    </CsScore>
    </CsoundSynthesizer>

Since the audio file “mary.wav” is non-looping, its output should include lines like this:

    WARNING: non-looping sample
    instr 1:  itim = 0.000
