The truck cabin filtering
= The truck cabin filtering =
There is the possibility of individual (per truck) sound filtering for the truck cabin truck.''(Added in 1.43 version)''<br>(''Hard-coded equalizer settings (automation) in the master bank has been removed since version 1.43.'')
= Sound processing =
* This state is controlled by the global parameter ''cabin_out'' (0 means inside, 1 means outside).
'''Window opening status (closed / open)
* This state is controlled by the global parameters ''wnd_left'', ''wnd_rigthwnd_right'' (0 means closed, 1 means opened).
'''Sound processing'''

! Window !! Audio bud bus !! opened !! closed

| Left || ['''Rtn window_left'''] || .effect.add.window_eq.opened || .effect.add.window_eq.closed
Please be very careful when setting a large difference boundaries for the low_crossover, high_crossover parameters on the same equalizer.
Large differences can generate unwanted sound patterns.
 
= Sound attenuation depending on the position of the listener =
 
Sound attenuation is controlled by an equalizer (3-EQ) , which is located on the ['''Rtn window_out'''] audio bus.
The equalizer setting is individual for each truck (from version 1.43) and is part of the interior sound settings.

|-
! Listener !! Audio bus !! inside !! outside
|-
| Listener || ['''Rtn window_out'''] || .effect.equalizer.cabin.inside || .effect.equalizer.cabin.outside
|}
The transition between the equalizer limit parameters is linearly approximated by the application.
Please be very careful when setting a large difference boundaries for the low_crossover, high_crossover parameters on the same equalizer.
Large differences can generate unwanted sound patterns.
 
= Reverb in the cabin =
Reverb in the cabin depends on both the position of the listener and the state of opening / closing the windows.
The reverb setting is processed only on the final mix of all three audio buses.
(''Within the sound bank, the Reverb effect is placed on the [Grp cabin] audio bus.'')
 
The reverb setting is individual for each truck (from version 1.43) and is part of the interior sound settings.
{| class="wikitable"
|-
! Reverb !! Audio bus !! inside !! outside
|-
| reverb effect || ['''Grp cabin'''] || .effect.reverb.window.closed || .effect.reverb.window.opened
|}
The transition between the reverb limit parameters is linearly approximated by the application.
The external reverb should correspond approximately to the external (open) environment. Therefore, we recommend a setting that does not change the echo too much.
