platformio:
- remove ABL_MILLIAMPS_DEFAULT from build_flags_min, set default 1500 in const.h
- add default in wemos_shield_esp32_4MB_max_base
- add wemos_shield_esp32_16MB_SPM1423_max
arti_wled.h: bugfix use all leds in 2D
usermod_v2_customeffects.h: fill black if call==0
index.js and xml.cpp: bin name: replace one _ by ' ' to enable line wrap in info tab and ota update
- prepare for merging upstream
--> audiorective files should stay the same after merging!
- makuna just release NeoPixelBus 2.7.1 -> use for "V4" build
* Grouping um settings, add pre and post Info, update SR & 4LD settings
Settings_um.htm:
- modify addField (grouping)
- addInfo (pre and post texts)
Add preInfo to audio reactive and 4ld usermod
Extra:
platformio: wemos_shield: add audio reactive usermod and update to alt display
* um settings: cpp: lowercase, js: initcap
* um settings: txt only pre, txt2 only post and initCap as function
* Fix rotary encoder info string

- hide "Analog Mic PIN" setting if I2S-ADC is not supported by the hardware
- In case of usupported config (PDM or ADC), overwrite dmType with default.
This introduces an optional band pass filtering step to remove low frequency noise. Very effective for PDM mics - reduces noise floor by a factor of 100 !
- I2S DAC devices utilize the complete sample range [-32767 ... 32768], while I2S microphones typically deliver samples in [-2047... 2047]. Down-scaling Line-in samples ensures that filters and AGC operate optimally.
- use aPLL clock source for I2S with MCLK
- experimental: I2S slave mode (however could not get it to work ...)
A few goodies from my development branch, before I continue refactoring so much that I can't extracts nothing anymore.
- GEQ fades a bit slower
- updates to mic profiles
- simple peak detection without FFT (low freqs only)
it's possible that volume samples become negative. In this scenario, our simple noise gate does stupid things, and it looks like "effects temporarily lost the sound".
This fix improves the situation, and makes sure that volume samples are always >= 0.
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.
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`
