Hello all,

Does anyone know where I can find some example code for an ADPCM 16:4-bit algorithm?

I've checked the archives here, and saw a similar question for an 8:2-bit algorithm that didn't get much response, so I won't hold my breath :)

I've searched several variations in google, with little luck.

I've seen an article in a design magazine of this implementation with a PIC, so I assume it can be done with an 8052.

Thanks in advance.
