AFINITFILEFORMAT(3)AFINITFILEFORMAT(3)NAME
afInitFileFormat - initialize file format of an audio file setup
SYNOPSIS
#include <audiofile.h>
void afInitFileFormat(AFfilesetup setup, int fileFormat);
PARAMETERS
setup is a valid file setup created by afNewFileSetup(3).
fileFormat is an integer constant specifying a file format.
DESCRIPTION
Given an AFfilesetup structure created with afNewFileSetup(3), afInitFileFormat initializes the file format to that specified by
fileFormat.
The following file formats are currently supported:
AF_FILE_RAWDATA
raw audio data
AF_FILE_AIFF
Audio Interchange File Format
AF_FILE_AIFFC
Audio Interchange File Format AIFF-C
AF_FILE_NEXTSND
NeXT .snd/Sun .au
AF_FILE_WAVE
Microsoft RIFF WAVE
AF_FILE_BICSF
Berkeley/IRCAM/CARL Sound File
AF_FILE_AVR
Audio Visual Research
AF_FILE_IFF_8SVX
Amiga IFF/8SVX
AF_FILE_SAMPLEVISION
Sample Vision
AF_FILE_VOC
Creative Voice File
AF_FILE_NIST_SPHERE
NIST SPHERE
AF_FILE_CAF
Core Audio Format
ERRORS
afInitFileFormat can produce the following errors:
AF_BAD_FILESETUP
setup represents an invalid file setup.
AF_BAD_FILEFMT
fileFormat represents an unknown file format.
AF_BAD_NOT_IMPLEMENTED
fileFormat represents a file format which is not currently implemented.

afInitAESChannelDataTo, afInitAESChannelData - initialize AES non-audio data in an audio file setup
SYNOPSIS
#include <audiofile.h>
void afInitAESChannelDataTo(AFfilesetup setup, int track, int willHaveData);
void afInitAESChannelData(AFfilesetup setup, int track);
PARAMETERS
setup is a valid file setup returned by afNewFileSetup(3).
track specifies a track within the audio file setup. track is always AF_DEFAULT_TRACK for all currently supported file formats.
willHaveData is a boolean-valued integer indicating whether AES non-audio data will be present.
DESCRIPTION
Given an AFfilesetup structure created with afNewFileSetup(3) and a track identified by track (AF_DEFAULT_TRACK for all currently supported
file formats), afInitAESChannelDataTo initializes the track to contain or not contain AES non-audio data. afInitAESChannelData behaves
similarly but always initializes the track to contain AES non-audio data.
Currently only AIFF and AIFF-C file formats can store AES non-audio data; this data is ignored in all other file formats.
ERRORS
afInitAESChannelDataTo and afInitAESChannelData can produce the following errors:
AF_BAD_FILESETUP
setup represents an invalid file setup.
AF_BAD_TRACKID
track represents an invalid track identifier.
