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

fc703f53cf lavfi/af_compensationdelay: replace pow(x,0.5) by sqrt(x)
sqrt is faster, and is sometimes more accurate depending on the libm.

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.

4020787b5b avfilter/avf_showspectrum: make colors for log scale more user friendly
Previosly output was almost useless because background noise, due to
windowing function picked and which is not actually present in audio,
had too much brightness.
Now output of sine wave matches more with SoX.
