Sigtuna DAR 3 - Edit Screen

Original Author(s): Miki Azuma

To open the "Edit screen", select "Edit screen" (F9) in the "Tools" pull down menu, or click the "Edit screen" button in the toolbar.

The edit screen is made up of three main areas - the menu and toolbar, the working area and the status bar. The NCC.HTML file is shown in the NCC tree view to the left. The upper right window is the "Event list" which shows the details of the selected NCC item, such as text and audio "events". Below the Event List is the browser window where the synchronized XHTML document is shown.

If a book is a "ToC only book", the table of contents, or Navigation Control Center representing the NCC.HTML is shown in this browser window. The musical note icon in the folders in the NCC tree view indicates that the NCC item contains audio. This lets you know easily and quickly which NCC items contain audio and which do not.

Attention!! The first event in an NCC item must always be a text event, the text that is the heading of the NCC item. Do not delete or move this event as this is the text event which contains the link to the NCC.

The "Audio Clip Display" is at the bottom of the screen. The wave form of the audio events is shown in this display. When you navigate to an audio event which is coded in PCM or ADPCM2, the wave form for that clip is drawn in this display.
When the audio is played back, the peak meter control, located in the lower right of the screen, shows the current peak values and the current time position for the event.

The current NCC item will be highlighted in the browser display on the right when an NCC item is selected. When you move to another event or NCC item, the browser display and highlighting will change to reflect this.

When detailed audio wave editing is required, you can use the "Audio edit" function (CTRL+A), accessible in the "Tools" pull down menu on the "Edit screen". This editor displays the wave form of the selected event and is useful for very detailed audio editing such as the removal of unwanted noises in the recorded audio or slight adjustment. Any changes to the audio data also affect the SMIL file.

Editing Audio Events

The key points in this section are:

  • Move audio events
  • Split and join to adjust an event length
  • Delete errors
  • Delete or split an audio event which contains only 'silence'
  • Split or remove noises
  • Editing (join or split) the audio event corresponding to the first event (Table of Contents)

When an NCC item is selected, the audio event corresponding to the NCC title will be played back. If the NCC item is very long there may be more than one audio event corresponding to that item, that is, the audio may be split into more than one event. If this is the case, you can join these audio events so that the audio for the entire heading is heard when it is selected. Please note that the maximum playback time of a single audio event on the edit screen is 10 seconds, therefore an audio event longer than 10 seconds will not play out to the end.

[HINT] When the text of the text event is not displayed on the event list, select "Application options" in the "View" pull down menu, or click the "Application settings" button, which is the "i" icon in the toolbar, then check the "Display XHTML text in the event list" box and select "OK".

After the audio event editing is complete the text events are moved. This is explained in the next section, "Move events in the event list".

If you plan to add text using ATAU, it is better to edit audio events considering the length of the text you want to synchronize later. If you will be using Auto HTML mode in ATAU, editing of the audio events in relation to the text events is important.

Move Events in the Event List

Click the event number to select an event. Once you have selected an audio event and it is highlighted, you can move in the event list with the up and down arrow keys. In order to move the selected event upward or downward, select "Move event up/down" (CTRL+F9 / SHIFT+CTRL+F9) in the "Edit" pull down menu, or Move Event buttons in the toolbar.

Delete Audio Events

Select the event that you want to delete and select "Delete" (Del) in the "Edit" pull down menu, or click "Delete event(s)" button, which is the "x" icon button on the toolbar. When the confirmation message is shown, select "Yes" to finalize the deletion.

[HINT] If you delete an audio event by mistake, there is the "Undo" function which enables you to undo once.

Join Audio Events

Select one of the two events you want to join, then drag the mouse up or down one audio event so that both events are highlighted or, use SHIFT + Up/Down Arrow Keys. Select the "Join audio events" (CTRL+J) in the "Audio event edit" pull down menu, or click the "Joins two audio events" button on the toolbar. When the confirmation message is shown, click "Yes" to complete the joining process.

[HINT] If you receive a message that the two selected audio events cannot be joined, you will need to Cleanup that NCC item before the join can be made. When this happens close the "Edit screen" and return to the "Main screen". Go to "Cleanup" in the "Edit" pull down menu and select "Cleanup current NCC item" (CTRL+F5) in the pull down menu. Return to the "Edit screen", and try to join the events again. You can also join two audio events by using Audio Edit. Removing the current navigation point in Audio Edit is another way to join two audio events.
When you happen to delete an event by mistake, there is the "Undo" function which enables you to undo once.

Split Audio Event

When you select an audio event in the "Edit screen", the wave form is shown in the "Audio clip display" and the marker on the wave form moves corresponding to the playback position of the audio event. Place the cursor on the "Audio clip display" where you want to split the event. Select "Play one audio event" (Return) in the "Control" pull down menu and it will playback from that point. If the position for the split is not correct, you can adjust it with the Right and Left Arrow Keys.

Once you have set the correct position to split, select "Split audio event" (Ctrl+S) in the "Audio event edit" pull down menu. When the confirmation message is shown, click "Yes" to complete the split.

NCC Editor (Move NCC Items)

Attention!! Please be aware that when you use the "Synchronized book" option and create a project with an existing XHTML file, you must not edit (change, move, split, or delete) the NCC items.

When you create a new project using the "ToC only book" option, it may be necessary to adjust the level or position of some of the NCC items. To open the "NCC editor", select "Move NCC items" (F4) in the "Edit" pull down menu, or click the "Move around one or more NCC items in the NCC" button on the tool bar. When an NCC item is select in the editor, you can move it up/down and also change its level using the NCC editing buttons at the bottom left of the editor.

If you need to make a change to the actual headings, for example if a word in the heading is misspelled, go to the NCC tree view on the "Main screen" or the "Edit screen". You can change names of the headings in the same way you change folder names in Windows.

Add Page

Attention!! When you create a project with "Synchronized book", page numbers must not be added, deleted or edited. This function only adds or edits page numbers in the NCC.html file, it does not change the content of the XHTML files. It is therefore important to make sure the source documents contain all of the correct and necessary information before creating a new project using "Synchronized book".

When you need to add pages to the book, you must find the correct insert position. Open the "Edit screen" and find the audio event containing the audio page information, or if the pages are not announced in the audio and there is no audio event for the page number, find the event where the new page starts. Select "Add/edit page"(CTRL+P) in the "Edit" pull down menu, or click the "Add page" button in the tool bar to add a page.

When the "Add new page mark" dialog is open, ensure that "page-normal" is selected. Enter the page number in the "Begin page" column (leave the "End page" field as it is, with "?") and then click the "Add" button. Now, the page information is inserted as a text event, immediately before the selected audio event.

[HINT] When you open the dialog again after inserting a page, the next page number is highlighted in the "Begin page" column.

Text Event Synchronization

[HINT] The process sequence for text synchronization is as follows: after finishing editing an audio event, you do text event synchronization before moving on to the audio event editing of the next NCC.

When you import audio files into an NCC item the first event in the event list will always be a text event, which is then followed by a number of audio events. If there are other text events in the NCC item, these other text events will appear after the the imported audio events.

If there is a large number of events in an NCC item, they will not all be displayed in the event list at the same time. The scroll bar on the right allows you to scroll through the event list.

[HINT] When the text of the text event is not displayed on the event list, select "Application options" in the "View" pull down menu, or click the "Application settings" button, which is the "i" icon in the toolbar, then check the "Display HTML text in the event list" box and select "OK".

Text synchronization steps

  • Check the wording in the text event.
  • Find the audio event corresponding to the words in the text.
  • Memorize the audio event number, then select the text event.
  • Move the text event to the audio event number by the "Move one event one step up" button in the toolbar or "Move event up"(CTRL+F9) in the "Edit" pull down menu.

The position before the audio event is the synchronization point of the audio event and the text event. Once you select a text event in the event list, the corresponding text in the browser window is, and will stay, highlighted until you select the next text event or a synchronized audio event in the list.

Attention!! If the project is extremely large or the number of the events in one NCC item exceeds 400, the processing speed may be slower depending on the computing capacity. Please do not try to operate too quickly, especially when the computer has low processing capacity. If you are editing very quickly and the computer is not able to process the information quickly enough, the SMIL file can be damaged.

Audio Event Synchronization with Images

With Sigtuna DAR 3, you can also synchronize images. The synchronized project with images can be played back with LpPlayer or other DAISY playback software. The book will also play on a DAISY hardware player, but the images cannot be displayed.

Attention!! When a project will contain both synchronize text and images, do the text synchronization first, and then move on to image synchronization on the "Edit screen".

Image synchronization steps

  • Select the audio event which you want to synchronize with the image.
  • Select "Insert image" (CTRL+G) in the "Edit" pull down menu or click the "Insert image" button in the tool bar.

'Insert image' in the 'Edit' pull down menu

  • The "Insert image into SMIL" dialog opens.
  • Select the drive and the folder that contains the image file.
