===========================
NAME
----
afSetVirtualByteOrder, afSetVirtualChannels, afSetVirtualPCMMapping,
afSetVirtualSampleFormat - set the virtual data format for a track in
an audio file
SYNOPSIS
--------
#include <audiofile.h>
int afSetVirtualByteOrder (AFfilehandle file, int track, int byteOrder);
int afSetVirtualChannels (AFfilehandle file, int track, int channels);
int afSetVirtualSampleFormat (AFfilehandle file, int track,
int sampleFormat, int sampleWidth);
int afSetVirtualPCMMapping (AFfilehandle file, int track,
double slope, double intercept, double minclip, double maxclip);
PARAMETERS
----------
* 'file' is an AFfilehandle which refers to an open audio file and is
usually created by afOpenFile.
* 'track' is an integer which identifies a particular track in an open
audio file. The only valid track is `AF_DEFAULT_TRACK` for all
currently supported file formats.
* 'sampleFormat' is an integer which denotes a virtual sample format.
Valid values are `AF_SAMPFMT_TWOSCOMP`, `AF_SAMPFMT_UNSIGNED`,
`AF_SAMPFMT_FLOAT`, and `AF_SAMPFMT_DOUBLE`.
* 'sampleWidth' is a positive integer which specifies the number of bits
in a sample.
* 'channels' is a positive integer which specifies the number of
interleaved audio channels in the given audio track.
* 'byteOrder' is an integer which specifies the virtual byte order of
samples in the given audio track. 'byteOrder' can be either
`AF_BYTEORDER_BIGENDIAN` or `AF_BYTEORDER_LITTLEENDIAN`.
* 'slope' and 'intercept' are double-precision floating point values which
indicate the audio data sample slope and zero-crossing value,
respectively, for the given sample format.
* 'minclip' and 'maxclip' are double-precision floating point values
which indicates the minimum or maximum sample values to be returned.
Any values less than 'minclip' will be set to 'minclip', and any values
greater than 'maxclip' will be set to 'maxclip'.
RETURN VALUE
------------
These functions return 0 for success and -1 for failure.
