Sigtuna DAR 3 - ATAU (Audio & Text Addition Utility)

Original Author(s): Miki Azuma

The ATAU (Audio & Text Addition Utility) is the tool for synchronizing text with an existing audio recording. You can add text to a "ToC only book" created by Sigtuna DAR 3 and also to a project created in another application. The ATAU function cannot be used unless there is audio in the project. It can also be used for revising text in a XHTML file.

To start the ATAU, select "ATAU" (F11) in the "Tools" pull down menu or click the "ATAU screen" button in the tool bar. The confirmation message is shown, click "Yes".

Attention!! VERY IMPORTANT: DO NOT click the links in browser on the upper part of the screen after finishing synchronization.
An error message will be shown, and there will be problems in the project that you are unable to fix using Sigtuna DAR 3.

When you add text to an "Audio with NCC only" book with ATAU, it creates "atau****.html" files, one ATAU.html file for each NCC heading created. The files are automatically named randomly. You can find out the names of the files from Edit Screen. Choose "View current HTML file" (Shift+Ctrl+F11) in the "View" pull down menu.

ATAU Screen

At the top of the ATAU screen, there are four buttons that are used to navigate between the NCC headings. From the left to right they are: "Done" (Alt+F4), "Prev. NCC" (CTRL+PageUp), "Goto NCC" (F10) and "Next NCC" (CTRL+PageDown). "The current NCC item number" and "The total number of the NCC items" counter is shown in the upper right corner of the screen.

The working area consists of the two main parts. The upper half of the ATAU screen is the browser window where the synchronized document is displayed. It shows the XHTML file which corresponds to the current NCC item. Below it, there are three tab pages that corresponds to the three different ATAU text modes. You can change the mode by selecting the tab for the mode you require.

Control buttons such as "Play current audio event" (F6), "Repeat current audio event" (F5) and the buttons to move an event are at the bottom left of the screen. Immediately to the right of the control buttons there are four information displays indicating "The current event number and the total events number", "The event type", "The elapsed time of the current event" and "The total time of the current event".

There is a single button on the right side of the three tab pages, the "Do synch" (CTRL+Return) button. This button is used either on the "Manual typing" or the "Manual HTML" tab page. When you are certain that the text displayed on the tab page corresponds correctly to the audio event, click the "Do synch" button. This synchronizes the text with the audio event. Once they are synchronized you can move to the next event.

Attention!! If you select the "Do synch" button before the audio event has been played back completely to the end, the audio event will be divided into two events at the point where "Do synch" was selected.
To help you to avoid this, you have the option to increase the ATAU playback speed up to 300%. The speed can be changed on the "SigtunaDAR3 Options" dialog (CTRL+L) in the "Options" pull down menu.
Attention!! VERY IMPORTANT: DO NOT click the links in browser on the upper part of the screen after finishing synchronization.
An error message will be shown, and there will be problems in the project that you are unable to fix using Sigtuna DAR 3.

Types of Text Input Mode

The ATAU contains the three types of input mode: "Manual typing", "Manual HTML" and "Auto HTML". You can select the mode by selecting the tab for the mode that you will use.

Manual Typing

This mode is useful when you want to add text to existing audio material such as a recorded lecture with no script, or audio books without text. It can be used for summarized text synchronization, which can help people to better comprehend the contents of the audio material, or revising text of existing synchronized books.

When you select this mode the first audio event is played back. The text displayed in the tab window is the NCC item. Ensure that the audio event corresponds to the text. Click the "Do Synch" button (CTRL+Return) for synchronization.

Summary of Steps

  • The audio event is played back.
  • Type text manually.
  • Click the "Repeat current audio event" button (F5) when you need to listen to the current audio event again. The audio event will play back again.
  • When you are sure that the text you have typed correctly corresponds to the audio event, click the "Do Synch" button (CTRL+Return) for synchronization.

Repeat these steps for each audio event.

The steps for revising text of a XHTML file is described below.

Locate the NCC item to be changed using the navigation buttons in the upper right. When the text of the NCC item to be changed is displayed in the tab window, revise the text, then click "Do Sync" button to finalize. If one text event is synchronized with more than one audio event, check to determine if the text is synchronized with the correct audio event. To do this, simply click the "Play current audio event" (F6) button.

Attention!! You can only revise the text where there is no link from that text event. If you try to revise the text which is linked to a different part of the project, you may destroy a link and therefore destroy a project.

Manual HTML

When a text file or an (X)HTML file is available, you can add text semi-automatically with the Manual HTML mode. To use this mode, open an existing (X)HTML or text file by clicking the 'Open source' button which is on the left of the tab page. The text of the file is now displayed in the text window.

When you start synchronizing, playback the first audio event by clicking the "Play current audio event" button (F6), the audio playback will stop automatically when that audio event has been played. The first text event is already there as a NCC title. It is therefore not necessary to synchronize to that event. You can delete the unnecessary text from the text browser. You can then move to the next step: click the "Play current audio event" (F6) button to playback the second audio event.

The steps are given below.

Steps

  • Set the cursor (with the keyboard or by clicking with the mouse) at the end of the text to be synchronized and the text before that position will be highlighted.
  • Click the "Repeat current audio event" button (F5) when you need to listen to the current audio event again. The audio event will play back.
  • When you are sure that the text you have selected corresponds correctly to the audio event, click the "Do Synch" (CTRL+Return) button for synchronization.

The synchronized text is now added to the XHTML window above the text window, and that text is automatically removed from the text window. Repeat these steps for each audio event. When you finish the NCC item, move to the next NCC item using the "Next NCC" (CTRL+PageDown) button in the upper right corner of the ATAU screen.

Please be aware that each time you begin synchronizing a NCC item, you must not synchronize the first audio event. Delete the text corresponding to the ToC in the text window and move on to the next audio event, otherwise the project may have serious problems that you are unable to repair.

Attention!! If you select the "Do synch" button before the audio event has been played back completely to the end, it will split that audio event into two at the place where you pressed "Do synch".
To help you to avoid this, you have the option to increase the ATAU playback speed up to 300%. The speed can be changed in the "SigtunaDAR3 Options" dialog (CTRL+L) in the "Options" pull down menu.

Auto HTML

Preparation of a proper (X)HTML file and audio events can difficult for the effective use of the "Auto HTML" mode. The (X)HTML file must contain 'elements' at correct places. Each larger segment in the (X)HTML must have certain elements, such as "span" elements, placed at the beginning and the end of these text segments. The audio events have to be edited to accord with the elements of the (X)HTML file. If these conditions are met, this mode is very efficient.

Unlike the other two modes, in this mode, the playback does not stop automatically- it will play continuously until it reaches the end of the SMIL file. Synchronization will complete in the total playback time.
