+      This is caused by that IPP samples is by default built using '''dynamically linked CRT''' ({{{/MD}}} compiler option). A simple way to solve this is by modifying the {{{makefile}}} of {{{speech-codec}}} samples, for example by inserting the following line to {{{ipp-samples\speech-codecs\Makefile}}} line 46:
