If your manipulating data using a C program, you'll need to include the following: #include <multimedia/ulaw2linear.h> For a description of the conversion functions, execute: man -M /usr/demo/SOUND audio_ulaw2linear To compile, you'll need to add /usr/demo/SOUND to your include path. To link, you'll need link in /usr/demo/SOUND/libaudio.a Hope this helps. --- ------------------------------------------------------------------ | Ron Zuckerman E-mail: ronzu@isu.comm.mot.com | | Phone: (708)538-3134 FAX: (708)538-2818 | ------------------------------------------------------------------ | "A madman got us into this, and it's beginning to look as if | | only a madman can get us out." -- Chekov | ------------------------------------------------------------------
