This section describes Intel IPP functions which generate tone samples, triangle samples, pseudo-random samples with uniform distribution, and pseudo-random samples with Gaussian distribution, as well as special test samples.
Some sample-generating functions operate with data in the fixed point format. These functions have Q15 suffix in their name. This means that integer data are used in calculations inside the function as real numbers equal to the integer value multiplied by
2-15 (where “
15” is called a scale factor).
