Classes
struct	AudioInfo
	Basic Audio information which drives e.g. I2S. More...
class	AudioInfoSource
	Supports the subscription to audio change notifications. More...
class	AudioInfoSupport
	Supports changes to the sampling rate, bits and channels. More...
class	AudioWriter
	E.g. used by Encoders and Decoders. More...
class	int24_3bytes_t
	24bit integer which is used for I2S sound processing. The values are really using 3 bytes. It works only on little endian machines! More...
class	int24_4bytes_t
	24bit integer which is used for I2S sound processing. The values are represented as int32_t, but only 3 bytes are used. If you assign values which are too big, they are clipped. More...
class	MovingAverage< N >
	Caclulates the moving average of a number of values. More...
class	NumberConverter
	Converts from a source to a target number with a different type. More...

Typedefs
using	Pins = Vector< int >
	Type alias for a collection of pin numbers.
using	sample_rate_t = uint32_t
	Type alias for sample rate values.

Enumerations
enum	MemoryType { RAM , PS_RAM , FLASH_RAM }
	Memory types.
enum class	MTSStreamType {   VIDEO = 0x01 , VIDEO_H262 = 0x02 , AUDIO_MP3 = 0x03 , AUDIO_MP3_LOW_BITRATE = 0x04 ,   PRV_SECTIONS = 0x05 , PES_PRV = 0x06 , MHEG = 0x07 , H222_0_DSM_CC = 0x08 ,   H222_1 = 0x09 , A = 0x0A , B = 0x0B , C = 0x0C ,   D = 0x0D , H222_0_AUX = 0x0E , AUDIO_AAC = 0x0F , VISUAL = 0x10 ,   AUDIO_AAC_LATM = 0x11 , SL_PES = 0x12 , SL_SECTIONS = 0x13 , SYNC_DOWNLOAD = 0x14 ,   PES_METADATA = 0x15 , METDATA_SECTIONS = 0x16 , METADATA_DATA_CAROUSEL = 0x17 , METADATA_OBJ_CAROUSEL = 0x18 ,   METADATA_SYNC_DOWNLOAD = 0x19 , IPMP = 0x1A , VIDEO_AVC = 0X1B , VIDEO_H222_0 = 0x1C ,   DCII_VIDEO = 0x80 , AUDIO_A53 = 0x81 , SCTE_STD_SUBTITLE = 0x82 , SCTE_ISOCH_DATA = 0x83 ,   ATSC_PROG_ID = 0x85 , SCTE_25 = 0x86 , AUDIO_EAC3 = 0x87 , AUDIO_DTS_HD = 0x88 ,   DVB_MPE_FEC = 0x90 , ULE = 0x91 , VEI = 0x92 , ATSC_DATA_SERVICE_TABLE = 0x95 ,   SCTE_IP_DATA = 0xA0 , DCII_TEXT = 0xC0 , ATSC_SYNC_DATA = 0xC2 , SCTE_AYSNC_DATA = 0xC3 ,   ATSC_USER_PRIV_PROG_ELEMENTS = 0xC4 , VC1 = 0xEA , ATSC_USER_PRIV = 0xEB }
	PMT Program Element Stream Types.
enum	RxTxMode { UNDEFINED_MODE = 0 , TX_MODE = 1 , RX_MODE = 2 , RXTX_MODE = 3 }
	The Microcontroller is the Audio Source (TX_MODE) or Audio Sink (RX_MODE). RXTX_MODE is Source and Sink at the same time!
enum	TimeUnit { MS , US , HZ }
	Time Units.

Functions
static void	checkMemory (bool printMemory=false)
	Executes heap_caps_check_integrity_all()
void	stop ()
	stops any further processing by spinning in an endless loop
void	waitFor (bool &flag)
	wait for flag to be active
