<P>
Reading a file containg floating point data (allowable with WAV, AIFF, AU and other
file formats) using integer read methods (sf_read_short() or sf_read_int()) is
discouraged as the library cannot guarantee sensible results. For instance the data
in the file may have a maximum absolute value &lt; 1.0 which would mean that all sample
values read from the file will be zero.
file formats) using integer read methods (sf_read_short() or sf_read_int()) can
produce unexpected results.
For instance the data in the file may have a maximum absolute value &lt; 1.0 which
would mean that all sample values read from the file will be zero.
In order to read these files correctly using integer read methods, it is recommended
that you use the
<A HREF="command.html">sf_command</A>
interface a command of
<A HREF="command.html#SFC_SET_SCALE_FLOAT_INT_READ">SFC_SET_SCALE_FLOAT_INT_READ
and a parameter of SF_TRUE to force correct scaling.
