The Whooshkaa dashboard has out of the box support for annotating your audio with ad markers (pre-rolls, mid-rolls and post-rolls) as well as content markers.
For more information about ad-markers, please see this article.
Annotating your content with segment markers can also help you both remember what sections of an audio file are important content via "Audio Segments" as well as edit and crop an episode via "Remove Segments".
To create an Audio Segment marker at the current caret position, simply edit your episode, select to "Annotate" your audio and click the "SE" button in the toolbar:
This will place a segment right at the place of the caret. You can easily move the position of the marker by dragging its handles (start and end) or editing its parameters in the "Marker Details" section.
Keep in mind that Audio Segments are there just for you to annotate your audio and don't perform an action in the way that ad-markers or "Remove Segments" do.
Remove Segments are special types of markers that allow you to visually remove sections of audio from listener playback, without needing to crop and edit the audio itself. This enables you to easily take an existing segment and quickly convert it into a cropped region of audio.
To create a Remove Segment, simply create an "Audio Segment" (see section above) and change its type to a "Remove Segment.
That portion of the waveform will turn red, to indicate that the section is a Remove Segment.
Once you save your episode, the Whooshkaa media delivery engine will interpret that as a special portion of audio that will not be delivered to your listeners.
