Help is appreciated. If the Toshiba chip does indeed implement the standard ADPCM algorithm, it would be specified in G.721. (BTW...even if it is G.721, you need to know which one -- there were two.) You can get the CCITT fasciles through a place like Omnicom, but they are expensive. A good engineering library should have them as well. -- Chip Rosenthal | You aren't some icon carved out chip@chinacat.Unicom.COM | of soap, sent down here to clean Unicom Systems Development, 512-482-8260 | up my reputation. -John Hiatt
