FusionSound Reference Manual
FusionSound Types

FSSampleFormat

	FSSF_UNKNOWN	Unknown or invalid format.
	FSSF_S16	Signed 16 bit (linear).
	FSSF_U8	Unsigned 8 bit (linear).

The sample format is the way of storing audible information.

Data is always stored in native endian. This keeps the library and applications simple and clean. Always access sample buffers like arrays of 8 bit or 16 bit integers depending on the sample format, unless data is written with endianness being taken care of. This does not excuse from endian conversion that might be necessary when reading data from files.

FSBufferDescriptionFlags

	FSBDF_NONE	None of these.
	FSBDF_LENGTH	Buffer length is set.
	FSBDF_CHANNELS	Number of channels is set.
	FSBDF_SAMPLEFORMAT	Sample format is set.
	FSBDF_SAMPLERATE	Sample rate is set.
	FSBDF_ALL	All of these.

Each buffer description flag validates one field of the buffer description.

FSBufferDescription

	FSBufferDescriptionFlags	flags;	Defines which fields are set.
	int	length;	Buffer length specified as number of samples per channel.
	int	channels;	Number of channels.
	FSSampleFormat	sampleformat;	Format of each sample.
	int	samplerate;	Number of samples per second.

The buffer description is used to create static sound buffers.

FSStreamDescriptionFlags

	FSSDF_NONE	None of these.
	FSSDF_BUFFERSIZE	Ring buffer size is set.
	FSSDF_CHANNELS	Number of channels is set.
	FSSDF_SAMPLEFORMAT	Sample format is set.
	FSSDF_SAMPLERATE	Sample rate is set.
	FSSDF_PREBUFFER	Prebuffer amount is set.
	FSSDF_ALL	All of these.

Each stream description flag validates one field of the stream description.

FSStreamDescription

	FSStreamDescriptionFlags	flags;	Defines which fields are set.
	int	buffersize;	Ring buffer size specified as a number of samples (per channel).
	int	channels;	Number of channels.
	FSSampleFormat	sampleformat;	Format of each sample.
	int	samplerate;	Number of samples per second (per channel).
	int	prebuffer;	Samples to buffer before starting the playback. A negative value disables auto start of playback.

The stream description is used to create streaming sound buffers.

FSMusicProviderCapabilities

	FMCAPS_BASIC	basic ops (PlayTo, Stop)
	FMCAPS_SEEK	supports SeekTo

Information about an IFusionSoundMusicProvider.

FSBufferPlayFlags

	FSPLAY_NOFX	No effects are applied.
	FSPLAY_LOOPING	Playback will continue at the beginning of the buffer as soon as the end is reached. There's no gap produced by concatenation. Only one looping playback at a time is supported by the simple playback. See also CreatePlayback().
	FSPLAY_PAN	Use value passed to SetPan() to control the balance between left and right speakers.
	FSPLAY_ALL	All of these.

Flags for simple playback using IFusionSoundBuffer::Play().
