That's true, we could leave that part out, that will spare us 0.2%
dsp load.
You're missing the point. Which is that the frequency info
*should* be used to decide how to map bins to a new frequency.
Also, it's easy to reduce CPU load by letting the whole thing
run at a quarter of the system sample rate. Which means that
for one octave down everything above 3 kHz is gone. But I guess
CPU load was not the only reason for doing that.
