Arduino Audio Stream using PortAudio. More...

Inheritance diagram for PortAudioStream:

Public Member Functions
virtual void	addNotifyAudioChange (AudioInfoSupport &bi)
	Adds target to be notified about audio changes.

virtual AudioInfo	audioInfo () override
	provides the actual input AudioInfo

virtual AudioInfo	audioInfoOut ()
	provides the actual output AudioInfo: this is usually the same as audioInfo() unless we use a transforming stream

virtual int	available () override

virtual int	availableForWrite () override

bool	begin () override

bool	begin (PortAudioConfig info)

virtual void	clearNotifyAudioChange ()
	Deletes all change notify subscriptions.

PortAudioConfig	defaultConfig ()

PortAudioConfig	defaultConfig (RxTxMode mode)

void	end () override

virtual void	flush () override

bool	isNotifyActive ()
	Checks if the automatic AudioInfo update is active.

	operator bool ()

size_t	readBytes (uint8_t *data, size_t len) override

virtual size_t	readSilence (uint8_t *buffer, size_t length)
	Source to generate silence: just sets the buffer to 0.

virtual bool	removeNotifyAudioChange (AudioInfoSupport &bi)
	Removes a target in order not to be notified about audio changes.

void	setAudioInfo (AudioInfo in) override
	notification of audio info change

void	setNotifyActive (bool flag)
	Deactivate/Reactivate automatic AudioInfo updates: (default is active)

size_t	write (const uint8_t *data, size_t len) override

virtual size_t	write (uint8_t ch) override

virtual void	writeSilence (size_t len)
	Writes len bytes of silence (=0).

Protected Member Functions
int	bytesPerSample ()

PaSampleFormat	getFormat ()

virtual int	not_supported (int out, const char *msg="")

void	notifyAudioChange (AudioInfo info)

void	refillReadBuffer ()

void	startStream ()
	automatically start the stream when we start to get data
