Meh, linear interpolation (or cubic interpolation, for what matters) at just this mere 88.2 ksamples/second must be perfectly doable. Even an Arduino can do it without problems! However, receiving data from WLAN at a constant rate of 176.4 kB/s will be hard to impossible for this chip — refer to the netio benchmarks somewhere else on this forum.

thx
You might be able to get this to work. But to synchronize these systems you are going to need a semi-accurate RTC to track clock drift and enable you to add/delete samples to stay in sync. Add/delete samples requires a resampler running on the ESP8266. Might fit but it needs significant CPU horsepower. For a cheap system you can just delete one or duplicate one randomly but that will be audible some of the time; especially if you need correct by multiple samples.
