<h2>TAP Reflector</h2>
<img src="tap_reflector.png" alt="[TAP Reflector GUI as shown in Ardour]">
<p>
This plugin creates a psychedelic reverse audio effect. Overlapping
time intervals of incoming samples are treated as blocks called
'fragments'. Each fragment is reversed in time, and faded in and out
while played back to the output, hence creating a nearly constant
signal level with the mixture resembling a normal reverse-played track
-- with the difference that the audio actually progresses forward,
only pieces of it are reversed.
</p>

<h3>Usage tips</h3>
<p>
The <i>Fragment Length</i> setting has a great impact on the sound of
the effect. It is best to set it to approximately match the tempo of
the track, so the Fragment Length is equal to the time of one
measure. Other settings may also be interesting (particularly larger
ones). This is a very experimental effect, so experimentation is also
required when using it.
</p>
<p>
When mixed together with the dry signal, the effect is somewhat
similar to reverse reverberation. If you aim for such a sound, set the
<i>Wet Level</i> a few dB-s below the <i>Dry Level</i>. On the other
hand, raise the Wet Level if you want a really psychedelic effect. It
is especially worth trying this plugin on sustained guitar and vocal
tracks. Percussive sounds also create a very characteristic atmosphere
when played backwards.
</p>
<h3>Summary of user controls</h3>

<tr><th>name</th><th>min. value</th><th>default value</th><th>max. value</th></tr>
<tr align="center"><td>Fragment Length [ms]</td>
<td>20</td>
<td>415</td>
<td>1600</td></tr>
<tr align="center"><td>Dry Level [dB]</td>
<td>-90</td>

<td>20</td></tr>
<tr align="center"><td>Wet Level [dB]</td>
<td>-90</td>
<td>0</td>
<td>20</td></tr>
</table>
<h3>Notes</h3>
<p>
If for some reason you need longer Fragment Length times, it is safe
to raise the value set by the <code>#define MAX_FRAGMENT_LEN</code> at
the top of <code>tap_reflector.c</code>.
