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 void *in_ptr, size_t in_size)

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)
