64970772c7 optimization, and moving peak detection into own function
- save 1K of RAM by optimizing out
 fftBin[].
- moved several copies of the peak reset code into a single function
- moved peak detection out of getSample().
 - call peak detection function as last step of FFTcode. More optimal, and we can be sure that fresh FFT result are available.

Peak detection/reset are now called from both tasks, so I had to move some peak-related vars out of AudioReactive class and make them global (static).

5c792eb869 some cleanup and re-grouping of variables
- put variables with same context next to each other.
- removed a few vars that are not needed any more.
- replaced "16" by a more descriptive constant

bbc8049832 The Right Thing to Do (makes GEQ look awesome)
... found that stupid commit messages get more attention ;-)

- use 22050 Hz for sampling, as it is a standard frequency. I think this is the best choise.
- redesigned the GEQ channels (fftResult[]) for 22Khz, based on channels found on old HiFi equalizer equipment. 1Kzh is now at the center; Bass/Trebble channels are using 1/4 on left/right side respectively - similar to real equalizers. Looks nice :-)

- adjusted effects that use FFT_MajorPeak so that the maximum frequency is supported.

b8db47e528 AR: new freq scaling option "square root"

3c57e2e2b9 AR: special gain for GEO, some bugfixes andparameter tinkering
- new feature: "Input Level" (info page) can be used as global "GEQ gain" - only when AGC is ON (was already possible when AGC=off)

- some parameter tweaking in FFT function
- hidden feature: FFT decay  is slower when setting a high "dynamics Limiter Fall time" (steps: <1000, <2000, <3000, >3000)

- FFT_MajorPeak default 1.0f (as log(0.0) is invalid)
- FX.cppp: ensure that fftResult[] is always used inside array bounds

3e494cc551 removed broken frequency squelch, added frequency scaling options
- removed broken FFTResult "squelch" feature. It was completely broken, and caused flashes in GEQ.
- added Frequency scaling options: linear and logarithmic
- fixed a few numerical accidents in FX.cpp (bouncing_balls,  ripplepeak, freqmap, gravfreq, waterfall)

d92a93f1d5 AR: added dynamics limiter usermod cfg options
- On/Off controls the complete feature
- Rise Time and Fall Time are the minimum times (in milliseconds) for "volume" to go from 0% to 80% and back.
- when "On" we also use some filtering to smooth FFTResults[]. Rise and Fall Times do not affect Frequency reactive effects otherwise.

924073424f AR FFT task optimization - wait so I2S can fill its buffers

96d497a5cd AR: optimize sound sync, and code improvements
UDP audio sync: introduced new header version, because the new struct (without myvals[]) is not compatible with the previous struct. Also optimized structure size.
UDP audio sync: sender decides is AGC or non-AGC samples are transmitted.
getsamples: move volumeSmth/volumeRaw code out of AGC core function.
