Audio
kAudioFormatLinearPCM
Linear PCM, uses the standard flags.
kAudioFormatAC3
AC-3, has no flags.
kAudioFormat60958AC3
AC-3 packaged for transport over an IEC 60958 compliant digital audio interface. Uses the standard flags.
kAudioFormatAppleIMA4
Apples implementation of IMA 4:1 ADPCM, has no flags.
kAudioFormatMPEG4AAC
MPEG-4 Low Complexity AAC audio object, has no flags.
kAudioFormatMPEG4CELP
MPEG-4 CELP audio object, has no flags.
kAudioFormatMPEG4HVXC
MPEG-4 HVXC audio object, has no flags.
kAudioFormatMPEG4TwinVQ
MPEG-4 TwinVQ audio object type, has no flags.
kAudioFormatMACE3
MACE 3:1, has no flags.
kAudioFormatMACE6
MACE 6:1, has no flags.
kAudioFormatULaw
µLaw 2:1, has no flags.
kAudioFormatALaw
aLaw 2:1, has no flags.
kAudioFormatQDesign
QDesign music, has no flags
kAudioFormatQDesign2

kAudioFormatQUALCOMM
QUALCOMM PureVoice, has no flags
kAudioFormatMPEGLayer1
MPEG-1/2, Layer 1 audio, has no flags
kAudioFormatMPEGLayer2
MPEG-1/2, Layer 2 audio, has no flags
kAudioFormatMPEGLayer3
MPEG-1/2, Layer 3 audio, has no flags
kAudioFormatTimeCode
A stream of IOAudioTimeStamps, uses the IOAudioTimeStamp flags (see IOKit/audio/IOAudioTypes.h).
kAudioFormatMIDIStream
A stream of MIDIPacketLists where the time stamps in the MIDIPacketList are sample offsets in the stream. The mSampleRate field is used to describe how time is passed in this kind of stream and an AudioUnit that receives or generates this stream can use this sample rate, the number of frames it is rendering and the sample offsets within the MIDIPacketList to define the time for any MIDI event within this list. It has no flags.
kAudioFormatParameterValueStre<wbr />am
A “side-chain” of Float32 data that can be fed or generated by an AudioUnit and is used to send a high density of parameter value control information. An AU will typically run a ParameterValueStream at either the sample rate of the AudioUnit’s audio data, or some integer divisor of this (say a half or a third of the sample rate of the audio). The Sample Rate of the ASBD
describes this relationship. It has no flags.
kAudioFormatAppleLossless
Apple Lossless, the flags indicate the bit depth of the source material.
kAudioFormatMPEG4AAC_HE
MPEG-4 High Efficiency AAC audio object, has no flags.
kAudioFormatMPEG4AAC_LD
MPEG-4 AAC Low Delay audio object, has no flags.
kAudioFormatMPEG4AAC_ELD
MPEG-4 AAC Enhanced Low Delay audio object, has no flags. This is the formatID of the base layer without the SBR extension. See also kAudioFormatMPEG4AAC_ELD_SBR
kAudioFormatMPEG4AAC_ELD_SBR
MPEG-4 AAC Enhanced Low Delay audio object with SBR extension layer, has no flags.
kAudioFormatMPEG4AAC_HE_V2
MPEG-4 High Efficiency AAC Version 2 audio object, has no flags.
kAudioFormatMPEG4AAC_Spatial
MPEG-4 Spatial Audio audio object, has no flags.
kAudioFormatMPEGD_USAC
MPEG-D Unified Speech and Audio Coding, has no flags.
kAudioFormatAMR
The AMR Narrow Band speech codec.
kAudioFormatAMR_WB
The AMR Wide Band speech codec.
kAudioFormatAudible
The format used for Audible audio books. It has no flags.
kAudioFormatiLBC

kAudioFormatMicrosoftGSM
Microsoft GSM 6.10 – ACM code 49.
kAudioFormatAES3
This format is defined by AES3-2003, and adopted into MXF and MPEG-2 containers and SDTI transport streams with SMPTE specs 302M-2002 and 331M-2000. It has no flags.
kAudioFormatEnhancedAC3
Enhanced AC-3, has no flags.
kAudioFormatFLAC
Free Lossless Audio Codec, the flags indicate the bit depth of the source material.
kAudioFormatOpus
Opus codec, has no flags.
