fb00bef05f AR - necessary constants for 166Khz sampling rate
16kHz might be a good compromise on small MCU's:
- GEQ will show frequencies up to ~6Khz
- FFT process may use up to 32millis (-> 100% CPU load). Try to stay below <60% so FreeRTOS can schedule all tasks properly.

- more CPU time is left for other WLED, so it maintains LED FPS and stays responsive on web UI.

d7bc6b1be7 AR: optimization for small MCUs, part2
Only run FFT when the result will be used.
Please note that this also means that `FFTTime` shown in Info is only meaningful when there is sound input and not silence.

--> To get exact FFT times, the optimization can be disabled by compiling with `-D SR_DEBUG`

79776ae8bc AR: optimization for smaller MCUs
- this reduces "lagging behind" of I2S sampling on smaller MCU's. The maximum time for FFT is now ~20 millis.
- small improvement for SR_DEBUG

a766ddbebc make I2S microphones work with buggy IDF4.4.x
I2S microphones were not working any more in with the newest framework - only delivers silence.
Ther reason is stupid bug in espressif I2S "compatibility" driver: RIGHT and LEFT channel are swapped, so when only asking for LEFT, we get silence from RIGHT.

Workaround: simply change LEFT to RIGHT, until the problem is fixed in ESP-IDF --> Fix tested on "classic ESP32", but still need to check behavior on -S3.
Code compiles also on -S3, -S2, and -C3.

smaller changes:
- a few changes to use new APIs (MCLK, rouing and sample resolution)
- a few additional debug messages
- put correct value into _pinConfig.mck_io_num

77ace76e32 Bugfix: make UDP sound sync work in AP mode
- the connected() method only get called once a Wifi STA connection is established. UDP Sound Sync should also work when sender is in AP Mode.
- added a few comments that should help to understand the code structure.

37ba649930 audioreactive effect improvements
- Info Page: add a small horizontal line below usermod specific part. Improves readability.
- updated 2D mapping mode of some  1D soundreactive effects
- alllow some effects to fade slowly, even slower that possible with SEGMENT.fade_out(). Looks nice.

not sure why - most effects only fade when using SEGMENT.fade_out(), while some need SEGMENT.fadeToBlackBy().

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).

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.

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

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.
