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.
