What you will find is that there's a wide variation of complexity
depending on the sampling rate (from 8 kHz to 48 kHz), the number of
channels (mono or stereo), and the value you use for OPUS_SET_COMPLEXTY
(0 to 10). I recommend you try the version in git (master), since
there's been a lot of optimizations since 1.0.x.
