Incudine is also the name of a standalone executable. Please consult the
<code>INSTALL</code> file if you'd like to install it.
</p>
<p>
Here is a basic tutorial to introduce the command.
</p>
<pre class=""src src-sh"">mkdir incudine_tut
<span style=""color: #b0c4de;"">cd</span> !$
<span style=""color: #ff7f24;""># </span><span style=""color: #ff7f24;"">usage</span>
incudine -h
<span style=""color: #ff7f24;""># </span><span style=""color: #ff7f24;"">Simple files for the test</span>
cat &gt;foo.cudo &lt;&lt;'---'
(dsp! simple (freq db (env envelope) gate)
(stereo (* (envelope env gate 1 #'free)
(sine freq (db-&gt;linear db) 0))))
---
cat &gt;quux.rego &lt;&lt;'---'
with (env1 (make-adsr .1 .09 .9 .5))
0 simple 440 -14 env1 1
0 simple 220 -20 env1 1
0.5 simple 225 -26 env1 1
1 simple 448 -14 env1 1
3 simple 450 -20 (make-adsr 1 .2 .7 1 :curve :sin) 1
5 set-control 0 :gate 0
---</pre>
<p>
Note: the package is <code>INCUDINE.SCRATCH</code>
(nickname <code>SCRATCH</code>) by default.
</p>
<pre class=""src src-sh"">incudine foo.cudo -s quux.rego</pre>
<p>
It remembers orchestra+score in Csound, however we can use multiple
files and a lisp file can contain what you want, not necessarily
specific code for Incudine. A rego file (see <a href=""tutorial_03.html#rego-file"">Getting Start - Part 3</a>)
is transformed in an intermediate lisp file containing also the code
to execute the score in realtime or to write a soundfile to disk.
</p>
<p>
We get a soundfile `quux.wav' and two FASL called `foo.fasl' and
`quux.fasl'. If we run again the previous command line&#x2026;
</p>
<pre class=""src src-sh"">incudine foo.cudo -s quux.rego</pre>
<p>
&#x2026; the execution is faster, because we are using the compiled files.
A source file is re-compiled if:
</p>
<ol>
<li>the source is modified after the compilation</li>
<li>the command line arguments before the name of the source file are changed</li>
</ol>
<p>
There aren't options before foo.cudo, therefore it also works without
re-compilation:
</p>
<pre class=""src src-sh"">incudine foo quux</pre>
<p>
The sound is truncated after 5 beats; we can add some padding:
</p>
<pre class=""src src-sh"">incudine foo.cudo --pad 1.2 -s quux.rego</pre>
<p>
and only <code>quux.rego</code> is re-compiled, because the new argument
<code>`&#x2013;pad 1.2'</code> doesn't precede <code>foo.cudo</code>.
</p>
<p>
Changing the name of the output file:
</p>
<pre class=""src src-sh"">incudine foo.cudo -o <span style=""color: #ffa07a;"">""battimenti zincati.wav""</span> -s quux.rego</pre>
<p>
Score from standard input:
</p>
<pre class=""src src-sh"">echo '0 simple 1000 -6 (make-perc .1 1.5) 1' \
| incudine foo.cudo -d 2 -s - > rego-from-stdin-1.wav
cat quux.rego | incudine foo.cudo -o rego-from-stdin-2.wav -s -</pre>
