+<h2>TAP Fractal Doubler</h2>
+<img src="tap_doubler.png" alt="[TAP Fractal Doubler GUI as shown in Ardour]">
+<p>
+Originally developed to do vocal doubling, this plugin is suitable for
+doubling tracks with vocals, acoustic/electric guitars, bass and just
+about any other instrument on them. The effect is created by applying
+small changes to the pitch and timing of the incoming signal. These
+changes are created by one-dimensional random fractal lines producing
+<a href="pinknoise.html">pink noise</a>.
+</p>
+
+<h3>General information</h3>

+
+<h3>Usage tips</h3>
+<p>
+As it is well known, pink noise -- being between white and brown noise
+in terms of spectral density and other stochastic characteristics --
+is the closest to musical patterns in general. Therefore it is a
+natural choice to use pink noise to modulate small differences into
+the pitch and timing of the incoming signal. This way a second voice
+is obtained that sounds almost the same as the original. By mixing
+these two voices together, the desired effect can be achieved.
+</p>
+<p>
+This plugin uses two separate fractal lines to generate changes in
+pitch and timing. The controls <i>Time Tracking</i> and <i>Pitch
+Tracking</i> determine how "rough" and how big these changes are. When
+set to 0, changes are bigger and more chaotic ("bad backup
+singer"). When set to 1, changes are smaller and smoother ("better
+tracking of the original").
+</p>
+<p>
+The level of the two voices should be roughly the same. If the <i>Dry
+Level</i> and <i>Wet Level</i> settings are not equal, preferably the
+Dry Level should be higher (to mitigate any side-effects). If you set
+both levels to -3 dB, the resulting output level will match the input
+level, therefore giving you perfect conditions to do comparisons via
+the Bypass button.
+</p>
+<p>
+In addition to setting the levels of the two voices, you may add
+spatial separation between them by using the panner controls
+<i>Dry Left Position</i>, <i>Dry Right Position</i>,
+<i>Wet Left Position</i> and <i>Wet Right Position</i>. These controls
+range between 0 and 1, 0 meaning hard left and 1 meaning hard right
+position. The two voices each have a left and a right output, which
+you can independently pan into the stereo image of the plugin output
+using these controls.  For example, with the settings shown in the
+above screenshot, the dry voice is panned slightly to the left and the
+wet voice slightly to the right.
+</p>

+<h3>Notes</h3>
+<p>
+Samples of fractal lines are never reused. That is, not a single
+N-point fractal line is looped again and again, but a new fractal is
+generated when the old one has ended. For this reason, the plugin is
+not hard RT capable, since fractals are re-generated in a periodical
+manner, with a period that does not necessarily match the LADSPA
+buffer period. Also, every time the user adjusts one of the Tracking
+parameters, the corresponding fractal is regenerated with respect to
+the new setting.
+</p>
+<p>
+Please keep in mind that this plugin is only a replacement of real
+doubling, which (when properly done) yields much more enjoyable
+results. It's perfect to use the plugin as a tonal/spatial enhancer,
+but if you want a real doubing effect and you can afford it, please
+consider doing another real recording of the same vocal/instrument,
+possibly with subtle changes in microphone placement and/or tonal
+settings. No DSP can bring you the Real Thing.
+</p>
