Additional Inherited Members
Public Member Functions inherited from soundtouch::TDStretch
	TDStretch ()
virtual	~TDStretch ()
void *	operator new (size_t s)
	Operator 'new' is overloaded so that it automatically creates a suitable instance depending on if we've a MMX/SSE/etc-capable CPU available or not.
FIFOSamplePipe *	getOutput ()
	Returns the output buffer object.
FIFOSamplePipe *	getInput ()
	Returns the input buffer object.
void	setTempo (float newTempo)
	Sets new target tempo.
virtual void	clear ()
	Returns nonzero if there aren't any samples available for outputting.
void	clearInput ()
	Clears the input buffer.
void	setChannels (uint numChannels)
	Sets the number of channels, 1 = mono, 2 = stereo.
void	enableQuickSeek (BOOL enable)
	Enables/disables the quick position seeking algorithm.
BOOL	isQuickSeekEnabled () const
	Returns nonzero if the quick seeking algorithm is enabled.
void	setParameters (uint sampleRate, uint sequenceMS=DEFAULT_SEQUENCE_MS, uint seekwindowMS=DEFAULT_SEEKWINDOW_MS, uint overlapMS=DEFAULT_OVERLAP_MS)
	Sets routine control parameters.
void	getParameters (uint pSampleRate, uint pSequenceMs, uint pSeekWindowMs, uint pOverlapMs)
	Get routine control parameters, see setParameters() function.
virtual void	putSamples (const SAMPLETYPE *samples, uint numSamples)
	Adds 'numsamples' pcs of samples from the 'samples' memory position into the input of the object.
Static Public Member Functions inherited from soundtouch::TDStretch
