4.12 Audio Record, Edit.

This is the Audio - Record menu (accessed via the main menu,

or by pressing the respective quick select button in other

menus).

Use this menu to record your audio material by clicking on the

round red Record button. You can also use this function to

split, trim and name recordings.

(1) Use the volume display to adjust the volume level. Try to

set the recording volume level as high as possible so as to

obtain optimum sound quality, but do not over-modulate it.

Click on the scrollbar below the volume display to change the

volume level. Move the scrollbar to the left or right to reduce

(to a minimum of -12 dB) or increase (to a maximum of 19 dB)

the volume respectively. The range available depends on the

selected audio input. Flashing blue indicates that everything

is in order, ﬂashing yellow indicates a risk of over-modulation

during audio mixing (only if several over-modulated segments

are mixed), and ﬂashing red indicates over-modulation.

(2) If your system supports the "Sound" button, it can be used

if an analogue input has been selected, i.e. Microphone, Front

and Rear. Before recording audio material, click on the button.

A window is opened in which you can select the Treble and

Bass from -12 to 12 dB.

(3) Here you can see the audio input. The options available dif-

fer of course according to your particular model.

(4) Select between Mono and Stereo modes. When using a

mono microphone, check that Mono is actually selected. If

DV is selected as the input, you can also select Stereo B. In

this case, the sound is recorded from a second stereo audio

track of the input device, provided the input is in 12-bit, 32 kHz

mode. Not all DV input devices offer a facility for selecting this

mode, however.

(5) This ﬁeld displays the remaining capacity of the

audio partition.

(6) The audio samples which you have recorded are automati-

cally assigned a label (A 1, A 2, etc) in the audio list, and their

length displayed. If you have added an audio sample to one of

the sound tracks of the Audio-Mix menu, it is marked with a

small white point next to the length.

(7) The New Sample button opens a dialog in which the Sound,

Silence and Sine Wave Sound functions can be conﬁgured and

launched by means of the respective buttons.

The effect `Sound´ allows you to transform sound effects from

the audio pool (see chapter 4.7, point (13)) and thus use them

for the audio mix. Click onto the button `Select Sound´ to open

the audio pool selection.

Select the desired sound effect, exit both the audio pool and

the `New sample´ window with `Ok´.

Note: The length that can be set in the `New sample´ window

is not relevant - instead, the original length of the sound effect

is used.

• 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).

• 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

playback.

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 channel

crosstalk. You can select a width of between 0 and 175%.

• De-clicking reduces the click and crackle noises found in

particular on records. Use the De-click-Strength 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.

• De-noise reduces the noise level found on old tapes and

records. First, select a noise position. A high value for the

de-noise strength 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 be-

tween 31Hz to 16KHz.
