Classes
class	Sound::PCMStream< is16Bit, isUnsigned, isLE >
	This is a stream, which allows for playing raw PCM data from a stream. More...
class	Sound::PacketizedPCMStream

Namespaces
	Sound

Macros
#define	READ_ENDIAN_SAMPLE(is16Bit, isUnsigned, ptr, isLE)   ((is16Bit ? (isLE ? _stream->readUint16LE() : _stream->readUint16BE()) : (_stream->readByte() << 8)) ^ (isUnsigned ? 0x8000 : 0))
#define	MAKE_RAW_STREAM(UNSIGNED)

Functions
RewindableAudioStream *	Sound::makePCMStream (Common::SeekableReadStream *stream, int rate, byte flags, int channels, bool disposeAfterUse=true)
	Creates an audio stream, which plays from the given stream. More...
PacketizedAudioStream *	Sound::makePacketizedPCMStream (int rate, byte flags, int channels)
	Creates a PacketizedAudioStream that will automatically queue packets as individual AudioStreams like returned by makePCMStream. More...
