Inheritance diagram for SBCEncoder:

Public Member Functions
	SBCEncoder (int subbands=8, int blocks=16, int bitpool=32, int allocation_method=SBC_AM_LOUDNESS)

AudioInfo	audioInfo ()
	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

bool	begin ()
	Restarts the processing.

virtual bool	begin (AudioInfo info)

int	bytesCompressed ()

int	bytesUncompressed ()

virtual void	end ()
	Ends the processing.

virtual const char *	mime ()
	Provides the mime type of the encoded result.

	operator bool ()

void	setAllocationMethod (int allocation_method)
	Defines the allocation method: Use SBC_AM_LOUDNESS, SBC_AM_SNR.

void	setAudioInfo (AudioInfo from) override
	Defines the sample rate, number of channels and bits per sample.

void	setBitpool (int bitpool)
	Defines the bitpool (2-86?)

void	setBlocks (int blocks)
	Defines the number of blocks: valid values (4,8,12,16)

virtual void	setOutput (Print &out_stream)

void	setSubbands (int subbands)
	Defines the subbands: Use 4 or 8.

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

Protected Member Functions
int	codeSize ()
	Provides the uncompressed length (of the PCM data) in bytes.

int	frameLength ()
	Provides the compressed length in bytes (after encoding)

void	processByte (uint8_t byte)

bool	setup ()
	Determines audio information and calls sbc_init;.

void	writeBlocking (Print out, uint8_t data, size_t len)
