It time needed for after ti ' modifications is Ti ' that time needed for next tracing point i+1 original be, acoustic image run path it is corresponding it is former always when
A length of t, amended total duration is T, then Ti+1=Ti+Ti ', T=t+（Ti-ti）+（Ti’-ti’）.
If modification acoustic image is run the corresponding total duration in path, then the acoustic image is run each acoustic image TRAJECTORY CONTROL on path
Point corresponding moment and its time to needed for next acoustic image TRAJECTORY CONTROL point will all be adjusted.If acoustic image TRAJECTORY CONTROL point
The i former corresponding moment is ti, and the corresponding moment is Ti after adjustment, and acoustic image is run to next rail from current acoustic image TRAJECTORY CONTROL point i
Time needed for mark point i+1 originals be time needed for after ti ' adjustment for Ti ', the acoustic image corresponding former total duration in path of running is t,
Amended total duration is T, then Ti=ti/t* (T-t)+ti, Ti '=ti '/t*（T-t）+ti’.

Original sets the level that links with the ultralow frequency audio amplifier, and DeriveddB is the initialization level value of the ultralow frequency audio amplifier node,
DerivedTrim is the output level value after the ultralow frequency audio amplifier node sets link to some full-range cabinet nodes.
One ultralow frequency audio amplifier node may be configured as linking to one or more full-range cabinet nodes, after link, when full-range cabinet node
Output level, then the ultralow frequency audio amplifier node linked with it will output level automatically, to coordinate the battalion of full-range cabinet node
Make certain sound effect.For a ultralow frequency audio amplifier node link to a full-range cabinet node, only need to consider both
Distance, source of sound property and required audio etc., can set ultralow frequency audio amplifier node and follow the full-range cabinet node to broadcast automatically
Output level when putting, that is, link level.
As shown in figure 26, it is assumed that the ultralow frequency audio amplifier node 4 in audio amplifier distribution map links to 3 neighbouring full-range cabinets
Node, itself output level value of full-range cabinet node 21,22,23 is respectively Trim1, Trim2 and Trim3, ultralow frequency audio amplifier
Node 24 originally with each full-range cabinet point 21,22,23 link level value be respectively LinkTrim1, LinkTrim2 with
LinkTrim3.If it is Ratio that level is totally added ratio, ultralow frequency audio amplifier node 4 itself initialization level value is
DeriveddB, the last output level value of ultralow frequency audio amplifier node 4 is DerivedTrim, then have：
Ratio=10(Trim1+LinkTrim1)/10+10(Trim2+LinkTrim2)/10+10(Trim3+LinkTrim3)/10
DerivedTrim=10*log(Ratio)+DeriveddB
