## ftsr

ftsr — Returns the sampling-rate of a stored function table.

## Description

Returns the sampling-rate of a stored function table.

## Syntax

    ftsr(x) (init-rate args only)

## Performance

Returns the sampling-rate of a GEN01 generated table. The sampling-rate is determined from the header of the original file. If the original file has no header or the table was not created by these GEN01, ftsr returns 0. New in Csound version 3.49.

## Examples

Here is an example of the ftsr opcode. It uses the file ftsr.csd.

Example 407. Example of the ftsr opcode.

its output should lines like these:

    sampling-rate of table number 1 = 44100
    sampling-rate of table number 2 = 22050
    sampling-rate of table number 3 = 44100
    sampling-rate of table number 4 = 44100
