* fixed a few typo's in comments
* fixed 8266 specific warning about 'comparison of integer expressions of different signedness'
based on recommendations made by @willmmiles:
* make sure that audioSyncPacket is the same size (44bytes) on all platforms
* use static buffer for receiving (avoids heap fragmentation)
* copy receive buffer to local audioSyncPacket struct - avoids alignment problems
* esp32 only: to stay in sync with UDP, Udp.flush() is needed when Udp.parsePacket() is _not_ followed by Udp.read()
audioSyncPacket contains four "invisible" padding bytes added by the compiler. These need to be initialized to zero, as future versions of the protocol will make use of these fields.
Many bad quality analog mics are not centered properly at 1.6V, but stuck at 0V or stuck at 3.3V in silence. The bandpass filter removes DC offsets and improve signal quality.
* debug messages added to different initializers
* SPH0654::initialize() was having a wrong signature: uint8 instead of int8.
C++ can be a real bastard ;-)
Update ES8388Source::initialize and ES7243::initialize method signatures to match I2SSource::initialize so that when initialize is called on a AudioSource pointer the child class's method is used.
Remove sync receive
Disallow 2D effects on non-2D segments
Optimisations
Sync clarification
AR palettes
Return of 2 audio simulations
Bugfix in sync #3344
- remove excessive segments
- ignore inactive segments if not syncing bounds
- send UDP/WS on segment change
- pop_back() when removing last segment
Add pairing support for ESP-NOW sync
Reduce string RAM footprint
UDP parse optimisation
Make WizMote work with sync.
ESP-NOW wireless sync POC.
- caveat: devices have to be on the same channel
- clashes with WizMote handling ATM
* remove "not supported" warning on -S2
* minor tweaking of beat detector
* optimized parameters for arduinoFFT
* fixed a few implicit "double" promotions
* minor UDP protocol optimizations
* small optimization for fft task create / suspend
* completely remove analogmic settings for -S3/-S2/-C3 where analog is not supported
changes were already tested extensively in the MM fork.
