Sound control Sound control is used to adjust bass, mid and
treble tones .
Volume Use this function to increase or reduce the volume for
the audio sample in question from -20 to 6 dB .
Volume & fading is used to normalize the volume with select-
able 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 se-
lect within a range from -20 to 6 dB . Mono switches the stereo
signal to mono .
Mono 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
“ordinary” 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 loud-
speaker only .
front centre Sound is played through the front centre loud-
speaker only .
front right Sound is played through the front right-hand loud-
speaker only .
rear The sound is played through both rear loudspeakers .
The Silence button creates a completely silent audio sample
with which, for example, you can influence parts of another
audio sample indirectly for the duration of the silence (see
Audio-Mix - indirect volume control) . The silence created in
the audio bin has the length you have chosen . In addition, this
sample has been trimmed 5 seconds in the IN range and the
OUT range . Should you nevertheless need a slightly longer
silence, the range can be trimmed .
Use Sine Wave Sound to create a tone the frequency (440 Hz
or 1 kHz) and volume (-20 to 0 dB) of which you can define .
Soft crackling may be audible at the beginning and/or end of
the sinusoidal tone . This cannot be eliminated entirely during
play back .
The samples created in this fashion are added to your sample
list .
(8) Special can be used to apply a number of special effects to
the audio sample, many of which are however only available
or worthwhile on stereo audio samples . With these functions,
Bogart SE creates a copy which includes the desired changes,
i .e . the original audio sample is preserved unchanged . The fol-
lowing special functions are included as standard:
Width This function artificially increases the distance between
the loudspeakers . This increase is achieved by negative chan-
nel crosstalk . You can select a width of between 0 and 175% .
Declick Declick reduces the click and crackle noises found
in particular on records . Use the Declick-level slider to set the
value to de-clicking and de-crackling in the recording . Don’t
set this too high as this will have in an influence on the sound
quality .
Denoise reduces the noise level found on old tapes and
records . First, select a noise position . A high value for the de-
noise level will also reduce the audio quality . If you are working
with very noisy material, you must find a compromise .
Equalizer offers a 10-channel control for frequencies between
31Hz to 16KHz .
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 sides This function interchanges the left-hand and right-
hand channels .
Sound presets offers profiles, specifically suitable for classic,
jazz, rock, pop and dance music .
