AudioFormatFlags Enum

Definition

Namespace:

AudioToolbox

Flags describing the stream in the AudioStreamBasicDescription.

This enumeration supports a bitwise combination of its member values.

Fields

Name	Value	Description
AppleLossless16BitSourceData	1	Apple Lossless data, native endian, signed integers, 16 bits.
CafIsFloat	1
IsFloat	1	If this flag is set, the data is encoded using floating point values instead of integers.
LinearPCMIsFloat	1
AppleLossless20BitSourceData	2	Apple Lossless data, native endian, signed integers, 20 bits (24 bit aligned).
CafIsLittleEndian	2
IsBigEndian	2	If this flag is set, the data is encoded in big endian format otherwise it is in little endian.
LinearPCMIsBigEndian	2
AppleLossless24BitSourceData	3	Apple Lossless data, native endian, signed integers, 24 bits.
AppleLossless32BitSourceData	4	Apple Lossless data, native endian, signed integers, 32 bits.
IsSignedInteger	4	If the data encoded using integers (the IsFloat flag is cleared) this determines whether they are signed or unsigned.
LinearPCMIsSignedInteger	4
LinearPCMSampleFractionShift	7
IsPacked	8	Set if the sample bits occupy the entire available bits for the channel, clear if they are high- or low-aligned within the channel.
LinearPCMIsPacked	8
IsAlignedHigh	16	If set, sample bits are on the high bits.
LinearPCMIsAlignedHigh	16	Linear PCM audio format: if set, sample bits are on the high bits.
IsNonInterleaved	32	If set, the data is non-interleaved (monophonic).
LinearPCMIsNonInterleaved	32	If this flag is set then there are separate AudioBuffers for each channel, otherwise the data for the left and right channels is interleaved in the same buffer.
IsNonMixable	64	If set, the audio data is non-mixable.
LinearPCMIsNonMixable	64
LinearPCMSampleFractionMask	8064
FlagsAreAllClear	2147483648	Use this value to indicate that no flags are set. Use instead of the value zero, as that represents that no flag state is set.
LinearPCMFlagsAreAllClear	2147483648	Linear PCM audio format: all flags are set to zero. Use this instead of zero, which means that no flags are configured.

Remarks

The core set of flags describe properties of the audio stream (integer vs float values, endianess, interleaved) while the other flags are only used if the AudioFormatType is set to either LinearPCM (those are the values prefixed with LinearPCM) or AppleLossles (enumeration values prefixed with AppleLossles).
