tracks . This procedure modifies only the part of the adjacent
sample selected using Correction which is parallel to the se-
lected sample . The volume levels before and after the selected
sample remain unchanged .
• Volume control by means of wave form.The wave form is the
tool to use to increase or reduce the volume of an audio seg-
ment within an audio sample, for example in order to eliminate
a loud unwanted noise . Click on the desired audio sample to
highlight it in blue, then select the Envelop menu item . First
use Add to insert three anchor points into the volume display
beneath the wave form . In the area above all soundtracks are
displayed to give you a better overview .
Then click on the leftmost of these three points in order to
activate it . The color of the activated point changes from red
to green . You can now move it to the desired position either by
clicking on it again and dragging it with the trackball, by means
of the Position slider, or by clicking on the Range button .
Range causes the associated video still to be displayed in the
background, enabling the position of the point to be selected
according to its position within the video .
Place the first point horizontally ahead of the noise to be elimi-
nated, without however modifying the vertical position of the
point . Position the second point horizontally in the middle of
the noise and drag it at the same time vertically downwards to
dampen the sound . The third point marks the end of the noise:
it should therefore also be at the same horizontal level as the
first, but beyond the noise . Click on Create to reduce the vol-
ume of the noise substantially without changing the remainder
of the audio sample .
To reduce the volume of longer ranges, use four points and
drag the middle two points down .
The method of volume control employed in each case is there-
fore determined primarily by the task concerned:
• If the volume of a complete audio sample is simply to be
increased or reduced, direct volume control is the solution . Us-
ing the wave form for this purpose would be to use a sledge-
hammer to crack a nut .
• If an audio sample is to be dampened while another audio
sample is playing, for example the background music is to be
softened for the duration of a commentary, indirect volume
control is the most convenient solution . Modifying the audio
samples by means of the wave form or splitting the music
manually would also entail a disproportionate amount of work .
• If unwanted noises are to be eliminated from a audio sample
or over-modulated passages of an audio sample adjusted to
the general volume level, the wave form represents a power-
ful tool, albeit one which is not particularly easy to use . Once
an audio sample has been edited by means of the Wave Form
function, indirect volume control is however subject to certain
limitations .
5. Fading audio samples in and out.
To fade specific audio samples in and out gently, click on the
sample concerned to highlight it in blue . Now click on Fade
to call up a dialog in which you can bind fading in and out to
specific images, either by selecting a predefined time value, or
by clicking on and moving the appropriate fader .
6. Adding audio effects.
Audio effects (standard effects, surround effect, supplemen-
tary effects) can be added to individual audio samples in the
same way as to complete sound tracks .
• To add an audio effect to an individual audio sample, first
select the desired sample, highlighting it in blue . Then click on
Effects and select an effect from the list . If necessary, adjust
the effect . Then confirm your selection with Insert/Change . A
small fx at the right-hand end of the audio sample concerned
now indicates the presence of an audio effect in the overview
of all sound tracks .
• To add an audio effect throughout a complete sound track,
i .e . to all audio samples of a sound track, click on the fx sym-
bol on the left of the sound track concerned . Select an effect
from the list presented . Make any effect adjustments required,
then confirm your selection with Insert/Change . A white point
on the left-hand button indicates the presence of one or more
effects in the sound track concerned .
• To delete an audio effect again from a sound track or an au-
dio sample, call up the audio effect menu again (as described
above) and click on Remove . Remove functions irrespective
of the effect selected, leaving an effect-free audio sample or
effect-free sound track .
7. Checking audio mixing.
• Add the remaining audio samples in turn and adjust the vol-
ume, fading and effects as required .
• To check an individual audio sample in detail, first select the
desired audio sample, then click on the Timeline menu item .
The timeline display shows all audio tracks in relation to the
selected audio sample . You can use the scrollbar beneath the
timeline display to move the displayed passage, click to move
the sound track to a different audio sample, and call up the
functions Fade and Envelop from within the timeline display .
8. Creating audio.
Create the sound . The color control bar immediately beneath
the storyboard should no longer contain any yellow
components .
