For anyone following along, it was of course a stupid error. The large and small filters weren't being included due to a header search path problem.

I am no audio or audio codec expert by any stretch of the imagination but I am beginning to worry that the resampling code found in sndlib is insufficient for opus + iOS? Or perhaps my ignorance of the workings of opus has caused me to miss something stupid in regards to compilation or configuration, e.g., thumb, floating point, etc.? > > Any guidance would be greatly appreciated. > > Cheers, > Michael
