## 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 files ftlptim.csd, and Church.wav.

Example 305. Example of the ftlptim opcode.

The audio file “Church.wav” is a looped sample, its output should include lines like these:

    Base Note : 60	Detune    : 0
    Low  Note : 0	High Note : 127
    Low  Vel. : 0	High Vel. : 127
    Gain      : 1	Count     : 1
    mode      : 801
    start     : 4529	end       : 4912	count  :0
    mode      : 0
    start     : 0	end       : 0	count  :0
