+## To build:
+
+``` <!---sh-->
+    make all
+```
+
+
+## To use:
+
+``` <!---sh-->
+    ./prog
+```
+
+
+## Try:
+
+``` <!---sh-->
+    ./prog
+```
+
+and then play the resulting `prog.wav` using a sound player.
+
+
+## Judges' remarks:
+
+When you run the program, after several moments, a `prog.wav` sound file is produced.
+
+Using a sound player (you may find `sox(1)` is a good choice), you may enjoy the result.
+
+Can you figure out how it produces the various layers of instruments?
+
+
+## Author's remarks:
+
+
+### Obfuscations
+
+ - "Helpful" formatting
+ - Character salad
+ - Loop exit trying to hide by a switch statement
+ - Strong string encryption. By that I mean "fmt"=>"gnu".
+ - A `/*{*/` that throws off bracket matching in vim. Begun the editor wars
+   have! (Wait, I'm **on** the vim-team!)
+ - `cm` and `ap` stands for "allpass" and "comb", respectively.
+ - One effect was created with deliberate "memory corruption".
+
+To encourage tinkering I've obfuscated the song data and program (see Y()) less
+than the "library code". Sorry if you wanted to tinker with the library code!
+
+### Sound quality
+
+The sample rate of prog.wav is 256kHz because creating aliasing-free waveforms
+would require more code, but you can always oversample the audio and pass the
+anti-aliasing problem on to the audio player :-) However, the downsampler in my
+`mplayer(1)` is poor, but you can use the high-quality resampler in `sox(1)` to create a
+48kHz version:
+
+``` <!---c--->
+    sox prog.wav -r 48000 prog.48kHz.wav
+```
+
+### Tricks (the condescending part)
+
+ - Kick drum from sines, pitched up to create toms.
+ - Roland TR-808 style hi-hats (a bunch of high-pass filtered square waves).
+ - SID/C64-style snare drum (oscillates between noise and square wave).
+ - There's some FM synthesis in the bass.
+ - Schroeder reverberator a la Freeverb. The same building blocks are used for
+   the echo effect.
+ - Waveshaping/overdrive using tanh(x), ohh yeaaah..
+
+I used this Python snippet to generate `q0[2]` and `q0[3]`:
+
+``` <!---python-->
+    def X(s): print(hex(int(s.replace("x","1").replace(".","0")[::-1],2))) # not for iopcc-use
+    X(".x.x..xx.x.xx.xxx.xx.xxx..xx.xxx")
+    X("x.xx.x.x.x.xxxxxx.xx.xxx.xxxxxxx")
+```

+<pre><code>    ./prog</code></pre>
+<p>and then play the resulting <code>prog.wav</code> using a sound player.</p>
+<h2 id="judges-remarks">Judges’ remarks:</h2>
+<p>When you run the program, after several moments, a <code>prog.wav</code> sound file is produced.</p>
+<p>Using a sound player (you may find <code>sox(1)</code> is a good choice), you may enjoy the result.</p>
+<p>Can you figure out how it produces the various layers of instruments?</p>
+<h2 id="authors-remarks">Author’s remarks:</h2>
+<h3 id="obfuscations">Obfuscations</h3>
+<ul>
+<li>“Helpful” formatting</li>
+<li>Character salad</li>
+<li>Loop exit trying to hide by a switch statement</li>
+<li>Strong string encryption. By that I mean “fmt”=&gt;“gnu”.</li>
+<li>A <code>/*{*/</code> that throws off bracket matching in vim. Begun the editor wars
+have! (Wait, I’m <strong>on</strong> the vim-team!)</li>
+<li><code>cm</code> and <code>ap</code> stands for “allpass” and “comb”, respectively.</li>
+<li>One effect was created with deliberate “memory corruption”.</li>
+</ul>
+<p>To encourage tinkering I’ve obfuscated the song data and program (see Y()) less
+than the “library code”. Sorry if you wanted to tinker with the library code!</p>
+<h3 id="sound-quality">Sound quality</h3>
+<p>The sample rate of prog.wav is 256kHz because creating aliasing-free waveforms
+would require more code, but you can always oversample the audio and pass the
+anti-aliasing problem on to the audio player :-) However, the downsampler in my
+<code>mplayer(1)</code> is poor, but you can use the high-quality resampler in <code>sox(1)</code> to create a
+48kHz version:</p>
+<pre class="&lt;!---c---&gt;"><code>    sox prog.wav -r 48000 prog.48kHz.wav</code></pre>
+<h3 id="tricks-the-condescending-part">Tricks (the condescending part)</h3>
+<ul>
+<li>Kick drum from sines, pitched up to create toms.</li>
+<li>Roland TR-808 style hi-hats (a bunch of high-pass filtered square waves).</li>
+<li>SID/C64-style snare drum (oscillates between noise and square wave).</li>
+<li>There’s some FM synthesis in the bass.</li>
+<li>Schroeder reverberator a la Freeverb. The same building blocks are used for
+the echo effect.</li>
+<li>Waveshaping/overdrive using tanh(x), ohh yeaaah..</li>
+</ul>
+<p>I used this Python snippet to generate <code>q0[2]</code> and <code>q0[3]</code>:</p>
+<pre><code>    def X(s): print(hex(int(s.replace(&quot;x&quot;,&quot;1&quot;).replace(&quot;.&quot;,&quot;0&quot;)[::-1],2))) # not for iopcc-use
+    X(&quot;.x.x..xx.x.xx.xxx.xx.xxx..xx.xxx&quot;)
+    X(&quot;x.xx.x.x.x.xxxxxx.xx.xxx.xxxxxxx&quot;)</code></pre>
