Note: A stronger increase in some frequencies may possible
reduce the total volume to reduce overmodulation/clipping.
• Copy Channel
As can be seen under Mode, this function copies the left-hand
channel to the right-hand channel or vice-versa, as desired .
• Swap Channels
This function interchanges the left-hand and right-hand channels .
• Sound profiles offers profiles specifically suitable for classic,
jazz, rock, pop and dance music .
• Sound control is used to adjust bass, mids and treble.
• Volume
Use this function to increase or reduce the volume for the
audio sample in question from -20 to 6 dB .
• Volume & fades is used to normalize the volume with selecta-
ble fade in and fade out times . The level has a range between
-48db and 0db . Set the slider to 0 db and the music piece will
be raised to the maximum possible volume without clipping . If
you set a negative volume, the music will be quieter than the
maximum level . This does not necessarily reduce the volume
by a particular level, but instead changes it to a certain level .
Note that even if you apply the same normalization, some au-
dio may still "seem" to have a different volume . This is subject
to differing dynamics that aren't affected by this filter .
• Volume LR
Use this function to adjust the two channels (left and right) of
an audio sample separately . Here too, you can select within
a range from -20 to 6 dB . Mono switches the stereo signal to
mono .
• NOP
This function cannot be used to make any changes to your
audio sample . As with the image processing effects, it is used
by MacroSystem for internal debugging .
• Mute
This function mutes either the left-hand and/or the right-hand
channel as desired . In addition, you can also deactivate the
function using the `---´ button so that the audio track is only
muted for a specific period of time and so that you need not
remove the effect .
• Surround
The surround effect is used in conjunction with a surround
receiver or amplifier to assign the sound of an audio sample
to a certain channel, i .e . to a certain loudspeaker . It can be
used to create interesting acoustic impressions, in particular
during audio mixing with commentaries . On a normal mono or
stereo television set, surround audio is reproduced as „ordi-
nary“ audio, i .e . without surround effects, through a single or
two loudspeaker(s) . A film containing surround effects is thus
suitable for playing over any set . Once the surround effect has
been selected, the following options are available:
• front left
Sound is played through the front left-hand loudspeaker only .
• front centre
Sound is played through the front centre loudspeaker only .
• front right
Sound is played through the front right-hand loudspeaker only .
• rear
The sound is played through both rear loudspeakers .
• rear left
Sound is played over the rear left-hand channel only . This is
possible only with a receiver/amplifier which supports Pro
Logic II (trademark of Dolby Laboratories) . Without Pro Logic II,
sound is played simultaneously over the two rear channels and
the front left-hand channel, creating an effect which is similar
but not as clear .
• rear right
Rear right functions in a similar manner to rear left, but for the
right-hand rear channel .
In all cases, a mono audio sample is first generated from the
original stereo sample, as playback is ultimately through a
single loudspeaker only .
• Sample -> Scene
Clicking on the Sample -> Scene button creates a video se-
quence with black background from your audio sample, which
appears in the scene bin . You can use this video sequence as
a basis for further video operations (e .g . insert editing) . This
function can greatly simplify audio-based editing .
• Copy Sample
Clicking on the Copy Sample button creates an identical copy
of the the previously clicked sample in the list of audio sam-
ples on the right . This function is useful when you wish to use
both the original material and a modified version . The copy
appears in the samples list with the same name as the original,
but is identified with the suffix .K (e .g . A1 .K) .
• Clipboard
If your system supports this function, you can place the audio
sample onto a clipboard . Select the Clipboard to add samples
to it or to load samples into the current project .
The top of the screen has a list of all samples found in the
Clipboard . This list will be empty the first time you see it .
The following options exist:
• Add current sample: The sample currently selected is added
to the Clipboard .
