Hello, I am tryig to code a simple delay using a buffer. There is something wrong(no sound) and I'd appreciate it if someone could figure out what I'm doing wrong.
streamin in; streamout out; float i; float j; float dlybuffer[44100]; float delaytime =.5;
i=(i>=44100)&0;
dlybuffer[rndint(i)]=in;
j =rndint(i- (delaytime*44100));
i=i+1;
j= (j<0)& (44100+j); out=dlybuffer[rndint(j)];

Not sure what's wrong. Here's the code I use for a delay.
streamin in; streamout out; monoin offset; //delay in samples float array[88200]; float index; // index of input write float outdex; // index of output read offset = rndint(offset);
index=index+1; //increment index index=index-(index>=88200)&88200; //deal with overflow of write index array[index] = in; // write to array outdex = index - offset; // calc read point outdex=outdex + (outdex < 0)&88200; // deal with overflow of read index out=array[outdex]; // read array to output
It looks roughly equivalent to yours. Could be the round integers don't work inside variable assignments for arrays.

It's been a while since I've played with SM, but I am pretty sure it doesn't like expressions/function calls used as an array index - unless things have changed - I had lots of problems with this and in the end had to use a temporary variable like :-
tmp = a*x +b*y etc... somevar = array[tmp];

Hy all, here is an example. I added a 3rd var, (t) for (timeconversion). 😀 Hope that this is what you mean?
streamin in; streamout out; float i; float j; float t; float dlybuffer[44100]; float delaytime =0.9;
dlybuffer[i]=in;
t = delaytime * 44100 - 0.5; t = rndint(t);
j = i - t ; j = j+(j < 0) &+ 44100; // Edit j = dlybuffer[j];
i = i + 1; i = i - (i >= 44100) &44100;
out = j;

this is pretty much what I use
streamin in; streamout out; monoin delay;
float read; float index; float mem[88200];
//write index=index+1; index=index-(index>=88200)&88200; mem[index]=in;
// read read = index - delay; read = read + (read < 0)&88200; read = mem[read];
out=read;
the 'delay' input will expect samples so do an external conversion if you want a knob that reads in seconds

thanks for the help , I will try these code out
