Inheritance diagram for ADPCMDecoderXQ:

Public Member Functions
virtual AudioInfo	audioInfo ()

void	begin () override

virtual void	begin (AudioInfo info)

void	end () override

virtual bool	isResultPCM ()
	If true, the decoding result is PCM data.

	operator bool () override

virtual void	setAudioInfo (AudioInfo from) override

	Set look ahead bytes from 0 to 8.

void	setNoiseShaping (ADPCMNoiseShaping ns)
	Defines the noise shaping.

void	setNotifyAudioChange (AudioInfoSupport &notify) override
	Registers an object that is notified if the audio format is changing.

virtual void	setOutput (AudioOutput &out_stream)
	Defines where the decoded result is written to.

virtual void	setOutput (AudioStream &out_stream)
	Defines where the decoded result is written to.

virtual void	setOutput (Print &out_stream)
	Defines where the decoded result is written to.
