<para>
|
||
Voicetracking is a capability wherein custom "one-off"
|
||
content is created and inserted into logs, making it possible to
|
||
create programming that sounds very spontaneous and "live".
|
||
In Rivendell, such voicetracks are placed into a special type of audio
|
||
cart known as a voicetrack cart. These carts are automatically
|
||
created, deleted and managed by the voicetracker interface (part of
|
||
the RDLogEdit module), with no manual user intervention required.
|
||
The voicetracker module also includes extensive capabilities for
|
||
allowing customization of the transitions between log elements.

Before beginning voicetracking for a particular service, a
|
||
voicetracker group and pool of available cart numbers must be
|
||
configured in the RDAdmin module. These procedures are detailed in
|
||
the Rivendell Technical and Administration Guide.

|

A voicetrack marker is a meta event that can be inserted into a log
|
||
as a "placeholder" to others to indicate where a voicetrack
|
||
is to be recorded. Track markers can be inserted by RDLogEdit,
|
||
RDLogManager events or even embedded in data generated by external
|
||
schedulers.

<para>
|

To voicetrack a log, start the RDLogEdit module,
|
||
highlight the desired log and touch the
|
||
<computeroutput>VoiceTracker</computeroutput> button, opening
|
||
the VoiceTracker dialog. This dialog consists
|
||
of three major parts: the waveform area, the log list and the control
|
||
buttons.
|
||
</para>
|
||
<para>
|
||
The waveform area is in the upper center part of the dialog, and
|
||
consists of four "panes". The upper three display waveform
|
||
depictions while the fourth contains audition control buttons, an
|
||
audio meter and various counters. Directly below this is the log
|
||
list, showing a copy of the currently loaded log. The control
|
||
buttons occupy the bottom and right-hand edges of the dialog.

<title>Editing Transitions</title>
|

<para>
|
||
When an event is selected in the log list, a graphical depiction of
|
||
the transition into that event is loaded into the waveform area.
|
||
If the selected event and its prior event in the log is not a
|
||
voicetrack or track marker, then the selected event will be
|
||
displayed in the third pane of the waveform area and the previous
|
||
event displayed in the first pane. If the selected event or its
|
||
prior event is a voicetrack or track marker, then voicetrack or
|
||
marker will be displayed in the second pane of the waveform area.
|
||
</para>
|
||
<para>
|
||
Once selected, a transition can be auditioned by touching the play
|
||
button in the fourth pane of the waveform area. Play will start
|
||
from the left-hand edge of the topmost waveform. This start
|
||
location can be adjusted by dragging the topmost waveform to the
|
||
left or right by means of the mouse or touchscreen. If the
|
||
transition type of the selected event is SEGUE, it is also possible
|
||
to adjust the degree of audio overlap by dragging the second or
|
||
third waveform as well. It's possible to “undo” changes made in
|
||
the segue overlap by right-clicking on the waveform and selecting
|
||
<computeroutput>Undo Segue Changes</computeroutput> from the menu.
|
||
To make the overlap permanent,
|
||
touch the <computeroutput>Save</computeroutput> button. To restore
|
||
the transition to its default
|
||
state (calculated on the basis of segue markers from the Library)
|
||
touch the <computeroutput>Do Over</computeroutput> button.
|
||
The transition type can be changed by
|
||
right-clicking on an event and selecting the desired transition
|
||
type from the menu.

<para>
|

Once the desired voicetrack marker has been selected, the process
|
||
of recording a voicetrack consists of four steps, each initiated by
|
||
one of the four square control buttons in the upper right-hand
|
||
corner of the dialog.
|
||
</para>
|
||
<para>
|
||
To begin, touch the topmost
|
||
<computeroutput>Start</computeroutput> button. This will cause the
|
||
audio in the topmost pane to begin playing, with a cursor to show
|
||
playback position. To begin the actual
|
||
recording, touch the <computeroutput>Record</computeroutput> button.
|
||
To start the following event (in the third pane), touch the second
|
||
<computeroutput>Start</computeroutput>
|
||
button. Finally, to stop recording, touch
|
||
the <computeroutput>Save</computeroutput> button.
|
||
The record process can be
|
||
canceled at any time by touching the
|
||
<computeroutput>Abort</computeroutput> button, restoring the
|
||
transition to its default state. It is also possible to undo a
|
||
completed voicetrack by touching the
|
||
<computeroutput>Do Over</computeroutput> button.

|

Once completed, the segue overlaps into and out of a voicetrack can
|
||
be adjusted in the same manner as for simple transitions –i.e. by
|
||
dragging the appropriate waveforms with the mouse.

It is possible to adjust the audio fade levels applied during

transitions by means of rubber bands on the waveform displays.
|

These are green lines with small square targets. To adjust a rubber
|

band, use the mouse to grab one of the targets and drag it to the

In addition to recording in realtime, it's possible to import a
|

voicetrack directly from an audio file. To do so, select the
|
||
desired voicetrack marker and then touch the
|
||
<computeroutput>Import</computeroutput> button to open
|
||
the Import/Export Audio dialog. (For more
|
||
information on using the Import/Export Audio dialog, see Section
|
||
3.1.0 Importing Audio from a File). Once imported, the voicetrack
|
||
can be manipulated in the same manner as those that were directly
|

recorded.

If the event following a voicetrack has its Talk Time markers set,
|

it is possible to set the transition so that the end of the
|
||
voicetrack automatically aligns with the end of the Talk Time
|
||
(commonly referred to as hitting the post). To do this, simply
|

touch the <computeroutput>Hit Post</computeroutput> button.
