2fbdc4faf1 lavfi/avf_showspectrum: replace pow(x, 0.25) by sqrt(sqrt(x)) 
This is faster; precision assured as result is a float.

962727acb4 lavfi/vf_decimate: do not compare the first frame to itself. 
This is a waste of computing power and will result to 0,
making it always dropped.
Use maximum difference values instead.

9dba3f8f09 lavfi/af_sofalizer: remove exp2 and replace clz by ff_clz 
ff_clz is faster, and uses an intrinsic (at the moment on GCC). exp2 is
a wasteful function for a simple integer exponentiation.

Untested.

Replaces by real arithmetic. Tested the validity of these transformations separately.
Numerical differences are ~1e-15, and should not matter: it is not even
clear which is more precise mathematically.
