A 16-bit audio codec from Cirrus Logic/Crystal, designed to take multiple analogue audio inputs, convert them into a digital signal, apply filtering and then convert them back into a combined/mixed analogue audio signal.

It was pin-compatible with their earlier CS4216 from 3 years before, but differs from CS4216 in that it runs from either 5V or 3.3V (CS4216 requires 5V), provides different serial modes and uses different digital filters. 

Unlike its predecessors (CS4215 and CS4216), the CS4218 did not carry the MwaveTM moniker, despite it being used on later IBM Mwave cards.
