<B>cfilein </B>- Creation of interface objects for the selection of audio
and analysis input files.

<H4>
<A NAME="DESCRIPTION"></A><U>DESCRIPTION</U></H4>
The <B>cfilein</B> command creates interface objects to handle input file
selection via a fileselector.
<P>Additionally, the<B> cfilein </B>object packs a small slider allowing
the user to define an offset into the selected soundfile.
<P>For a module to work, all <B>cfilein</B> objects present must be selected.
The user is warned if this is not the case. The label besides the
fileselection button can optionally be replaced with the option <B>-label.</B>
<P>CECILIA supports wave, aiff and SDII soundfile types. Files in the aifc
and next formats will be optionally converted when chosen in the file selector.
<P>Analysis files can also make use of the <B>cfilein </B>object. It is
however suggested that analysis file names carry an extension indicating
the type of analysis the file contains. <B>.lpc</B> indicates an lpc analysis,
<B>.pv</B> an fft analysis,<B> .hetro </B>an heterodyne analysis and <B>.cv</B>
a convolution analysis. CECILIA's built-in audio analysis interface automatically
extends the name of the analysis files with the appropriate suffix.
<P>The <B>cfilein</B> object can also be used to select midifiles for the
score. In this case the <B>-type</B> MIDI needs to be specified.
<H4>
<A NAME="SUBSTITUTION"></A><U>SUBSITUTION</U></H4>
When the orchestra and score are compiled, all instances of "[name]" (note
the quote marks) are substituted with full path name of the file selected
with the objects button. The offset is substituted, at the appropriate
place, with the use of [off<I>name_of_variable</I>].
<BR>
<H4>
<A NAME="EXAMPLES"></A><U>EXAMPLES</U></H4>
<TT>cfilein source -label "Sound to Process" -type audio</TT>
<P>would define a fileselection button in the Main window. In the orchestra,
the selected file (and its offset time) would substituted wherever the
following line is encountered:
<P><TT>asig, asid soundin "[source]",[offsource]</TT>
