NAME

       afInitCompression - initialize compression for a track in an audio file setup

SYNOPSIS

       #include <audiofile.h>

       void afInitCompression(AFfilesetup setup, int track, int compression);

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.

       compression is an identifier specifying the compression type (such as
       AF_COMPRESSION_G711_ULAW) to be used for audio data in the track.

DESCRIPTION

       Given an AFfilesetup structure created with afNewFileSetup(3) and a track identified by
       track (AF_DEFAULT_TRACK for all currently supported file formats), afInitCompression
       initializes the track to the specified compression.

       The following compression types are currently supported:

       AF_COMPRESSION_NONE
           no compression

       AF_COMPRESSION_G711_ULAW
           CCITT G.711 mu-law encoding

       AF_COMPRESSION_G711_ALAW
           CCITT G.711 A-law encoding

       AF_COMPRESSION_IMA
           IMA ADPCM encoding

       AF_COMPRESSION_MS_ADPCM
           MS ADPCM encoding

       AF_COMPRESSION_FLAC
           FLAC

       AF_COMPRESSION_ALAC
           Apple Lossless Audio Codec

ERRORS

       afInitCompression can produce the following errors:

       AF_BAD_FILESETUP

           setup represents an invalid file setup.

       AF_BAD_TRACKID

           track represents an invalid track identifier.

       AF_BAD_COMPTYPE

           compression represents an invalid compression type.
