This reader plays back sequenced entries.
Definition: SequenceReader.h:36
virtual int getLength() const =0
Returns an approximated length of the source in samples.
#define AUD_NAMESPACE_BEGIN
Opens the audaspace namespace aud.
Definition: Audaspace.h:116
This class represents a sound source as stream or as buffer which can be read for example by another ...
Definition: IReader.h:34
virtual void seek(int position)=0
Seeks to a specific position in the source.
#define AUD_API
Used for exporting symbols in the shared library.
Definition: Audaspace.h:93
virtual void read(int &length, bool &eos, sample_t *buffer)=0
Request to read the next length samples out of the source.
Specification of a sound source.
Definition: Specification.h:118
virtual Specs getSpecs() const =0
Returns the specification of the reader.
The IReader interface.
float sample_t
Sample type.(float samples)
Definition: Audaspace.h:126
ResampleQuality
Resampling algorithm and quality.
Definition: Specification.h:87
This device enables to let the user read raw data out of it.
Definition: ReadDevice.h:32
#define AUD_NAMESPACE_END
Closes the audaspace namespace aud.
Definition: Audaspace.h:119
virtual int getPosition() const =0
Returns the position of the source as a sample count value.
virtual bool isSeekable() const =0
Tells whether the source provides seeking functionality or not.
The ReadDevice class.
This class represents sequenced entries to play a sound scene.
