for (int i = 0; i < (arraysize * reps); i++)
    {
      j = i - k;
      if (j >= arraysize) {
        k = k + arraysize;  //signal repeat index offset
      }
      ti = a[j] * (sin(twopi * f * i * interval * 0.001)); //0.001 => time in seconds
      tr = a[j] * (cos(twopi * f * i * interval * 0.001));

I think there is a problem with the above code section where you check if j is greater or equal to the arraysize and then a couple of lines later index the a[] array with j.

Doesn't j need to be reset if equal to or greater than the arraysize?
