|
|
=====================
|
|
|
|
NAME
|
|
----
|
|
afInitSampleFormat, afInitByteOrder, afInitChannels, afInitRate -
|
|
initialize audio data format for a track in an audio file setup
|
|
|
|
SYNOPSIS
|
|
--------
|
|
#include <audiofile.h>
|
|
|
|
void afInitSampleFormat(AFfilesetup setup, int track, int sampleFormat,
|
|
int sampleWidth);
|
|
void afInitByteOrder(AFfilesetup setup, int track, int byteOrder);
|
|
void afInitChannels(AFfilesetup setup, int track, int channels);
|
|
void afInitRate(AFfilesetup setup, int track, double rate);
|
|
|
|
PARAMETERS
|
|
----------
|
|
`setup` is a valid file setup returned by linkaf:afNewFileSetup[3].
|
|
|
|
`track` specifies a track within the audio file setup. `track` is always
|
|
`AF_DEFAULT_TRACK` for all currently supported file formats.
|
|
|
|
`sampleFormat` is a symbolic constant specifying the sample format
|
|
for the audio data in the track. `sampleFormat` must be one of
|
|
`AF_SAMPFMT_TWOSCOMP`, `AF_SAMPFMT_UNSIGNED`, `AF_SAMPFMT_FLOAT`, or
|
|
`AF_SAMPFMT_DOUBLE`.
|
|
|
|
`sampleWidth` is a positive integer specifying the number of bits for
|
|
each sample in the track.
|
|
|
|
`byteOrder` is a symbolic constant specifying the byte order of
|
|
the track. `byteOrder` must be one of `AF_BYTEORDER_BIGENDIAN` or
|
|
`AF_BYTEORDER_LITTLEENDIAN`.
|
|
|
|
`channels` is a positive integer specifying the number of channels in
|
|
the track.
|
|
|
|
`rate` is a positive double-precision floating-point number specifying
|
|
the sample rate of the track.
|
|
|
|
DESCRIPTION
|
|
-----------
|
|
`afInitSampleFormat` initializes the track to the specified sample format
|
|
and sample width.
|
|
|
|
`afInitByteOrder` initializes the track to the specified byte order.
|
|
|
|
`afInitChannels` initializes the track to the specified number of channels.
|
|
|
|
`afInitRate` initializes the track to the specified sample rate.
|
|
|
|
ERRORS
|
|
------
|
|
`afInitSampleFormat`, `afInitByteOrder`, `afInitChannels`, and
|
|
`afInitRate` can produce the following errors:
|
|
|
|
[horizontal]
|
|
`AF_BAD_FILESETUP`:: `setup` represents an invalid file setup.
|
|
`AF_BAD_TRACK`:: `track` represents an invalid track identifier.
|
|
|
|
`afInitSampleFormat` can also produce the following errors:
|
|
|
|
[horizontal]
|
|
`AF_BAD_SAMPFMT`:: `sampleFormat` does not represent a valid sample format.
|
|
`AF_BAD_WIDTH`:: `sampleWidth` is not a valid sample width.
|
|
|
|
`afInitByteOrder` can also produce the following error:
|
|
|
|
[horizontal]
|
|
`AF_BAD_BYTEORDER`:: `byteOrder` does not represent a valid byte order.
|
|
|
|
`afInitChannels` can also produce the following error:
|
|
|
|
[horizontal]
|
|
`AF_BAD_CHANNELS`:: `channels` specifies an invalid number of channels.
|
|
|
|
`afInitRate` can also produce the following error:
|
|
|
|
[horizontal]
|
|
`AF_BAD_RATE`:: `rate` specifies an invalid sample rate.
