Hub75 is very memory hungry. So we try to make a bit more RAM available
* use 16bit samples when compiling with HUB75 support --> 3KB saved
* avoid using aPLL (HUB75 needs it)
* move audio buffers from BSS (always allocated) to heap (only allocated when FFTtask runs) --> 10Kb saved
* suspend live preview for 6 seconds when out-of-memory
adding hints for the compiler for optimization.
In case your custom build complains about "const", just remove the keyword. based on e82f38e277, but going further :-)
* "const" class functions : function does not modify any class attributes ( --> "this" becomes const)
* __attribute__((pure)) : function return value depends only on the parameters and/or global variables. The function does not modify any global or static variables.
* __attribute__((const)) : function only examines arguments (no globals), and has no effects except the return value. This slightly more strict than "pure"
* hot: tells the compiler "this functions is called very often"
* cold: the opposite of hot
AC minor patch cluster
* Anti-Aliased Lines and Circles
* replacing deprecated functions in ws.cpp
* using global brightness in analogue clock overlay
* fix for palette names (custom palettes)
* bugfix for UI: when resizing the window, it always jumped to the Colors tab
* UI: add webpage shortcuts for tabs
* mic quality: When set to "low noise" or "perfect", only minimal smoothing is performed on the "Mic Volume" input.
Every filter adds a delay, so this option can lead to better on-spot responses from effects.
* cleanup: removed a few unused variables and unused code.
* introducing sliding window FFT, which effectively doubles the rate of samples - and FFT results - produced per second. As a side-effect, it also makes FFT a bit less noisy.
As sliding window FFT requires double the number of FFT runs, the feature is only enabled on esp32 and esp32-S3.
the JS string can be shortened, by putting the usermod into a variable `ux` that is used instead of repeating the string 'Aduioreactive'.
For now its just an experiment, to see if the idea works on several browsers.
* use last remaining two bytes in audioSyncPacket for transmitting soundPressure
* 0x0 is treated as "legacy value" --> soundPressure = volumeSmth;
* decodeAudioData: ensure receivedPacket struct members are correctly aligned -
strictly speaking it is not safe to cast a uint8_t* as it does not offer any alignment guarantees.
* remove 8266 special handling in audioreactive::setup()
