ftlen ftlen ftlen Returns the size of a stored function table. Returns the size of a stored function table. ftlen(x) (init-rate args only) Returns the size (number of points, excluding guard point) of stored function table, number x. While most units referencing a stored table will automatically take its size into account (so tables can be of arbitrary length), this function reports the actual size if that is needed. Note that ftlen will always return a power-of-2 value, i.e. the function table guard point (see f Statement) is not included.As of Csound version 3.53, ftlen works with deferred function tables (see GEN01). ftlen differs from nsamp in that nsamp gives the number of sample frames loaded, while ftlen gives the total number of samples without the guard point. For example, with a stereo sound file of 10000 samples, ftlen() would return 19999 (i.e. a total of 20000 mono samples, not including a guard point), but nsamp() returns 10000. Here is an example of the ftlen opcode. It uses the file ftlen.csd, and mary.wav. See the sections Real-time Audio and Command Line Flags for more information on using command line flags. The audio file mary.wav is 154390 samples long. The ftlen opcode reports it as 154389 samples long because it reserves 1 point for the guard point. Its output should include a line like this: instr 1: ilen = 154389.000 ftchnls, ftlptim, ftsr, nsamp Author: &namebarry; MIT Cambridge, Massachussetts 1997 Example written by &namekevin;.
