Tone-Generating Functions

The functions described below generate a tone (or “sinusoid”) of a given frequency, phase, and magnitude. Tones are fundamental building blocks for analog signals. Thus, sampled tones are extremely useful in signal processing systems as test signals and as building blocks for more complex signals.
The use of tone functions is preferable against the analogous C math library's
sin()
function for many applications, because Intel IPP functions can use information retained from the computation of the previous sample to compute the next sample much faster than standard
sin()
or
cos()
.

Product and Performance Information

1

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
