3 The display of <dfn>waveforms</dfn> (or, more correctly, <dfn>peak
4 envelopes</dfn>, since the actual waveform is only visible at the highest
5 zoom levels) is configurable via the <kbd
6 class="menu">Edit > Preferences > Appearance > Editor</kbd> dialog, to support
7 different use cases and user preferences. The following options are
11 <tr><th>Show waveforms in regions</th>
12 <td colspan="2">By default, Ardour draws waveforms within audio regions. Disable this
13 option to hide them.</td></tr>
14 <tr><th rowspan="2">Waveform scale</th>
16 <td>This is the traditional <dfn>linear</dfn> (1:1) display of the
17 peak envelope, or, at higher zoom levels, the individual samples.</td></tr>
18 <tr><th>Logarithmic</th>
19 <td>Alternatively, a <dfn>logarithmic</dfn> display of the
20 peak envelope can be used. This will give a better idea of program loudness (it is similar
21 to dBs) and plot soft passages more clearly, which is useful for soft
22 recordings or small track height.</td></tr>
23 <tr><th rowspan="2">Waveform shape</th>
25 <td>The <dfn>zero</dfn> line appears in the middle of the display and waveforms
26 appear as positive and negative peaks above <em>and</em> below.</td></tr>
27 <tr><th>Rectified</th>
28 <td>The zero line appears at the bottom of the display and waveforms appear
29 as absolute peaks <em>above</em> the line only.</td></tr>
