<H3>Output Methods</H3>
The Output device provides methods for writing sound
samples out to the various channels of its associated output file.
The <CODE>ch1</CODE><A NAME="1"> and</A> <CODE>chL</CODE><A NAME="2"> methods</A> are equivalent, as are the
<CODE>ch2</CODE><A NAME="3"> and</A> <CODE>chR</CODE><A NAME="4"> methods.</A> Obviously <CODE>chL</CODE>
and <CODE>chR</CODE> are designed for use with two channel stereo
output. In each case <CODE><value></CODE> is an arbitrary mathematical
expression yielding a floating point value. There is no need to
ensure that the output samples stay within a predefined range, since
all <B>Tao</B> output files are normalised as a post-processing stage
before conversion into a more conventional integer-based format
such as WAV. This is achieved with the <CODE>taosf</CODE>
shell command (see section <A HREF="UserManual_41.html">*</A>).
