Chapter 4

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.
