delget/delset/delput/dliget
initialize and use delay lines
[note: These older delay functions have been replaced
by the
Odelay/Odelayi
objects.]
SYNOPSIS
#include <ugens.h>
delset(array,delvals,maxlength)
float *array,maxlength;
int *delvals;
float delget(array,wait,delvals)
float *array,wait;
int *delvals;
delput(signal,array,delvals)
float *array,signal;
int *delvals;
float dliget(array,wait,delvals)
float *array,wait;
int *delvals;
DESCRIPTION
These units are used to store and fetch samples from a delay
line. delset() is the initialization unit for delget(),
delput(), and dliget(). array is an array of floats which must
be at least maxlength words long, where this number is the
maximum size you expect to use (sampling rate * maximum
delay in seconds). delvals is an array of two integers used
for bookkeeping purposes. delput() stores signal in array,
and delget() fetches a sample from the pipeline where wai is the age of the sample in seconds. E.g. if wait is equal
to .5 at a sampling rate of 30000, delget() will look back
15000 samples. array must be dimensioned appropriately.
Naturally, delput() must be called before delget(), dliget()
is identical with delget() except that it will interpolate
linearly between samples according to the fractional part of
wait.
