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`
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
- added user-selectable frequency profiles, to allow adjustments for different I2S microphones (including line-in)
- additionally show "GEQ Input Level" as number in percent.
Encapsulated all parts with #ifdef that will not compile on newer ESP32 variants.
It's still a long way to go before we have a working version on -S3 and -C3, bus this should help to get us started.
From MoonModule/WLED repo.
- Updated ESP32 targets to use IDF 4.4.3 (thanks tasmota!)
- Fixed a compilation problem in ARTI (WLED_FS instead of LITTLEFS)
- Initial compilation support for ESP32-S3. Warning: there are still many problems to be solved before -S3 becomes usable!
- audioreactive: added #ifdef for features not yet supported on ESP32-S3
- 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.
- 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().
General (for CE, but also used by M12_pArc)
- add drawArc
Custom Effects
- add WLEDSR Custom Effects comment to places in WLED where it is hooked in
- move from wled.json to wledv123.json
- rename matrixWidth/Heigth to width/height and use virtualWidth/Height
- remove setPixels
- add drawLine / drawArc
