Classes
class	AudioInputMonitor
	Monitors audio input and reports if the volume exceeds a specified limit within a given period. More...
class	AudioStreamWrapper
	To be used to support implementations where the readBytes is not virtual. More...
class	BufferedStream
	The Arduino Stream supports operations on single characters. This is usually not the best way to push audio information, but we will support it anyway - by using a buffer. On reads: if the buffer is empty it gets refilled. More...
class	CallbackStream
	CallbackStream: A Stream that allows to register callback methods for accessing and providing and updating data. The callbacks can be lambda expressions. The update callback can also be used just to read the data without changing it. Warning: this class does not propagate audio info changes to the target stream. You need to do this manually. More...
class	ConverterStream< T >
	Both the data of the read or write operations will be converted with the help of the indicated converter. More...
class	FilteredStream< T, TF >
	Stream to which we can apply Filters for each channel. The filter might change the result size! More...
class	GeneratedSoundStream< T >
	Source for reading generated tones. Please note. More...
class	InputMerge< T >
	Merges multiple input streams. So if you provide 2 mono channels you get a stereo signal as result with the left channel from channel 0 and the right from channel 1. More...
class	InputMixer< T, SumT >
	MixerStream is mixing the input from Multiple Input Streams. All streams must have the same audo format (sample rate, channels, bits per sample). More...
class	MeasuringStream
	Class which measures the thruput. More...
class	MemoryStream
	A simple Stream implementation which is backed by allocated memory. More...
struct	InputMerge< T >::MergeRecord
class	ModifyingStream
	Abstract class: Objects can be put into a pipleline. More...
class	ProgressStream
	Generic calss to measure the the total bytes which were processed in order to calculate the progress as a percentage of the total size. More...
class	ProgressStreamInfo
	Configuration for ProgressStream. More...
class	RingBufferStream
	An AudioStream backed by a Ringbuffer. We can write to the end and read from the beginning of the stream. More...
class	Throttle
	Throttle the sending or receiving of the audio data to limit it to the indicated sample rate. More...
struct	ThrottleConfig
	Configure Throttle setting. More...
class	TimerCallbackAudioStream
	Callback driven Audio Source (rx_tx_mode==RX_MODE) or Audio Sink (rx_tx_mode==TX_MODE). This class allows to to integrate external libraries in order to consume or generate a data stream which is based on a timer. More...
struct	TimerCallbackAudioStreamInfo
	TimerCallbackAudioStream Configuration. More...
class	VolumeMeter
	A simple class to determine the volume. You can use it as final output or as output or input in your audio chain. More...

Namespaces
namespace	audio_tools
	Generic Implementation of sound input and output for desktop environments using portaudio.
