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.
Here is an example of the ftsr opcode. It uses the files ftsr.orc, ftsr.sco, and mary.wav.
Example 169. Example of the ftsr opcode.
/* ftsr.orc */ ; Initialize the global variables. sr = 44100 kr = 4410 ksmps = 10 nchnls = 1 ; Instrument #1. instr 1 ; Print out the sampling rate of Table #1. isr = ftsr(1) print isr endin /* ftsr.orc */
/* ftsr.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 /* ftsr.sco */
Since the audio file “mary.wav” uses a 44.1 Khz sampling rate, its output should a line like this:
instr 1: isr = 44100.000
