Constructor & Destructor Documentation

ADSRReader()

ADSRReader::ADSRReader	(	std::shared_ptr< IReader >	reader,
		float	attack,
		float	decay,
		float	sustain,
		float	release )

Creates a new ADSR reader.

Parameters

reader	The reader to read from.
attack	The attack time in seconds.
decay	The decay time in seconds.
sustain	The sustain level, should be in range [0 - 1].
release	The release time in seconds.

Member Function Documentation

read()

virtual void ADSRReader::read ( int & length, bool & eos, sample_t * buffer )

virtual

Request to read the next length samples out of the source.

The buffer supplied has the needed size.

Parameters

[in,out]	length	The count of samples that should be read. Shall contain the real count of samples after reading, in case there were only fewer samples available. A smaller value also indicates the end of the reader.
[out]	eos	End of stream, whether the end is reached or not.
[in]	buffer	The pointer to the buffer to read into.

Reimplemented from EffectReader.
