Airtime 2.1 for Broadcasters

Playlist builder

This page of the Airtime interface enables you to search the media library, sort and display the search results by the criteria that you choose, audition files and playlists, and drag and drop search results into an open playlist. You can also re-arrange the currently open playlist by dragging and dropping. The Playlist Builder page is not visible to Guest users.

Searching the library

On the left side of the Playlist Builder page, a table displays both the media files and the playlists in the Airtime library, with ten items shown per page by default. Use the drop-down menu at the top to choose from Files, Playlists, or All items. Click the Show drop-down menu in the top right corner to set the display of between 5 and 100 items per page, according to your preference. You can also click the Show/hide columns button to determine which metadata is displayed.

Click the metadata column headings such as Title, Creator, Album, or Genre to sort the entries in ascending or descending order. In the second column, audio files are represented by a loudspeaker icon, while playlists are represented by a document icon.

At the bottom of the window, click the First, Previous, Next, Last or individual page number buttons to browse the library.

Type a search term into the box in the upper left corner, with the magnifying glass icon. You can search by any library metadata stored in Airtime's database, whether that data is currently displayed or not. For example, to search for all files and playlists between four and five minutes long, enter 00:04 into the search box (for hours and minutes). Like an Internet search engine, the filtered entries shown are refined as you type - there is no need to press the Enter key on your keyboard.

Auditioning, downloading and uploading files

Clicking a file row in the table opens a pop-up menu which enables you to Play the file for audition in a pop-up window, Delete it from the Airtime library, Edit Metadata for that file, or Download it to your local computer for editing. The Delete option should be used with caution, because this action cannot be undone.

If you have checked the Enable SoundCloud Upload box on the Preferences page, there will be an additional option on the pop-up menu, Upload to SoundCloud. As mentioned previously, you should only upload audio files to SoundCloud with the permission of the copyright holder.

Right-clicking a file or playlist row in the search results will display all the available metadata for that item in a pop-up window.

Creating a new playlist

Once you have found the media that you require using the search box, you can create a new playlist on the right hand side of the Playlist Builder page. Click the New button to begin.

At first, the new playlist will be shown as Untitled Playlist. Click on the pencil icon to the right to give the playlist a name.


Enter the name you have chosen, then press the Return key on your keyboard to save the new name. You can edit the name of the playlist later by clicking on the pencil icon again.

Click the link View / edit description to expand a box where you can enter a Description for the playlist, then click the Save button. Setting good quality metadata here will help you find the playlist using the search box later, so you should be as descriptive as possible. 

Editing a playlist

With a playlist open, click on a file in the search results and then click Add to Playlist on the pop-up menu. Or drag and drop files from the search results on the left into the playlist on the right.

You can also select or deselect a whole page of search results using the button with the square icon, just below the search box. Alternatively, use the checkboxes in the first column of the table to select individual files. Then click the button with the plus icon to add your selection of files to the playlist. Files that you no longer require can be deleted from Airtime's library using the Trashcan button. 

After adding files to the playlist, the total playlist time is displayed in the top right corner. The duration of an individual file is shown in each row of the playlist in a white font, and beneath this figure the time since the beginning of the playlist is displayed in a smaller light grey font.

To audition a playlist file in your web browser, click the white triangle play button on the left side of its row. A pop-up audition window will open, with the playlist starting at the file you clicked. Click the small white x icon on the right hand side of each row to remove a file from the playlist. You can also drag and drop files to re-order them.

Click the playlist Fade button (two horizontal white arrows crossing in a grey rectangle), to the right of the New and Delete buttons, to open a beige bar in which you can set the Fade in and Fade out times for this playlist. The default fade time is set in the Preferences page on the System menu.

Click any one of the smaller Fade buttons between file rows to open another beige bar, which enables you to set fade in and fade out times between two adjacent files in the playlist. The fade buttons for adjacent files change to an orange background when you click them.

Each file in the playlist also has a button with two square brackets, which enables you to set cue in and cue out times for that particular file. Like the fade button, it changes to an orange background when you click it. The length of the file in the playlist is updated automatically, but the Original Length of the file is also displayed for your reference.

When your playlist is complete, click the New button in the top left corner to create another playlist, or browse to another page of the Airtime interface.

If you want to edit the playlist content or metadata later, you can find it by Title, Creator, Length or Uploaded Date using the search box on the Playlist Builder page. Click the playlist in the search results list, and then click Edit from the pop-up menu. You can also Play the entire playlist in a pop-up audition window, or Delete a playlist from this menu.
