<p>This tool can help you manually align text to audio, or adjust existing alignments.</p>
<p>To begin, load an audio file and a TXT or JSON file.</p>
<p>Split your text into lines if you use TXT.</p>
<p>For a JSON file, it should be like the following:</p>
<code>
[{"Start": <i>Starting time of this line in millisecond</i>, <br>
"Stop": <i>Ending time of this line in millisecond</i>, <br>
"Text":<i>The text of this line</i>},
...]
</code>
<p></p>
<p>After loading, play the audio for a few seconds so that the regions on the wave are placed at the correct positions.</p>
<p>There are some keyboard shortcuts to help you do your work easilier.</p>
<p><code>ENTER</code>: Play/Pause the audio<br>
<code>SPACE</code>: Play audio of the current line.<br>
<code>UP</code>: Go to previous line.<br>
<code>DOWN</code>: Go to next line.<br>
<code>LEFT / RIGHT</code>: Move the player cursor backward/forward.<br>
<code>CTRL + LEFT / RIGHT</code>: Skip to the previous/next region boundary.<br>
<code>F</code>: Set Start. <code>D</code>: Shift Start 10ms later. <code>S</code>: Shift Start 10ms earlier.<br>
<code>J</code>: Set End. <code>K</code>: Shift End 10ms earlier. <code>L</code>: Shift End 10ms later.
