- prepare for merging upstream
--> audiorective files should stay the same after merging!
- makuna just release NeoPixelBus 2.7.1 -> use for "V4" build
* audioreactive driver update
- Better handling of PDM and I2S Line-in
- Bugfixes for ES7243 (allocateMultiplePins)
- More error messages for ES7243
- sample scaling (needed for sources that use full scale of samples)
* audiorective update
* align SR_DEBUG with WLED_DEBUG
* optional bandpass filter (needed for PDM mics)
* sample scaling for PDM and Line-In
* small improvements for analog input
* bugfixes and small performance improvements
* code for FFT task refactored, for better readablity. Introduces separate functions for filtering and post-processing
* small improvement for beat detection
* default mic settings can be configured at compile time
* correct mic type if MCU does not support PDM or ADC
* hide analog PIN config if not supported by MCU
* audioreactive updates
- minor updates to source code (see discussion in PR #2907)
- usermod readme improvements
* small readme update
* one think I overlooked
* ok, another edit. Now its final. Hopefully.
* small upps
wrong parameter order in debug message.
* 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`
