Classes
class	Audio::PacketizedADPCMStream
Namespaces
namespace	Audio
	Internal interfaces to the ADPCM decoders.
Defines
#define	DK3_READ_NIBBLE(channelNo)
Functions
SeekableAudioStream *	Audio::makeADPCMStream (Common::SeekableReadStream *stream, DisposeAfterUse::Flag disposeAfterUse, uint32 size, ADPCMType type, int rate, int channels, uint32 blockAlign=0)
	Takes an input stream containing ADPCM compressed sound data and creates an RewindableAudioStream from that.
PacketizedAudioStream *	Audio::makePacketizedADPCMStream (ADPCMType type, int rate, int channels, uint32 blockAlign=0)
	Creates a PacketizedAudioStream that will automatically queue packets as individual AudioStreams like returned by makeADPCMStream.
Variables
