G.726 Functions

This section describes Intel IPP functions that can be used in implementing speech codecs following the ITU-T recommendations G.726 with Annex A.

These functions are used in the Intel IPP G.726 Speech Encoder-Decoder sample downloadable from http://www.intel.com/cd/software/products/asmo-na/eng/220046.htm.

The list of these functions is given in the table below.
