I guess, that you are referring to a digital audio PCM interface? If so, why don't you simply mention the involved chip and bit rate?

Usual audio chips PCM interface (I have been using Analog and TI up to now) is very similar to SPI, except for a slightly different frame sync signal. I don't understand, what you exactly mean with converting PCM to SPI respectively linking the two protocols.

A PCM interface is basically a shift register and some glue logic. It can be build in a few lines of HDL.
