Inheritance diagram for ADPCMEncoderXQ:

Public Member Functions
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 () override

virtual bool	begin (AudioInfo info)

void	end () override

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

	operator bool () override

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

void	setBlockSizePower (int pow)
	set bocksizes as 2^pow: range from 8 to 15

void	setLookahead (int value)
	Set look ahead bytes from 0 to 8.

void	setNoiseShaping (ADPCMNoiseShaping ns)
	Defines the noise shaping.
