 Constructions trigger random events at different frequencies,​ which can be used to play arbitrary sound sources regularly. They are named ''​randomX'',​ where X is a number between 1 and 64. For example ''​random16''​ is an event, triggered randomly at an average frequency of 16 seconds. Constructions trigger random events at different frequencies,​ which can be used to play arbitrary sound sources regularly.

 +==== Soundeffectsutil ====
 +
 +Transport Fever provides a number of scripts with utility functions. The soundeffectsutil.lua contains functions for creating soundsets:  ​
 +
 +  * ''​sampleCurve(nodes,​x)''​
 +  * ''​makeRoadVehicle2(speeds,​ idleSpeed, idleGain0, driveSpeed, speed01)''​
 +  * ''​squeal(speed,​ sideForce, maxSideForce)''​
 +  * ''​chuffs(speed,​ chuffStep, chuffsFastFreq,​ weight, refWeight)''​
 +  * ''​clacks(speed,​ weight, numAxles, axleRefWeight,​ gameSpeedUp)''​
 +  * ''​brake(speed,​ brakeDecel, maxGain)''​
 +
 +Some of these functions are described below.
 +
 +== makeRoadVehicle2(speeds,​ idleSpeed, idleGain0, driveSpeed, speed01) ==
 +
 +This function provides gain and pitch curves for a two track sound set of a motorized road vehicle. The first track is for the idle sound, the second one for the drive sound. The function requires the following parameters:
 +  * ''​speeds'':​ a list of 3 speed fractions between 0 and 1 to determine the "​keyframes"​ for the sound curves.*
 +  * ''​idleSpeed'':​ parameter for the pitch of the idle noise
 +  * ''​idleGain0'':​ parameter for the gain of the idle noise
 +  * ''​driveSpeed'':​ parameter for the pitch of the drive noise
 +  * ''​speed01'':​ speed parameter (usually ''​input.speed01''​)
 +
 +* The three values are used for:
 +  - point at which the idle noise can be heard at full volume
 +  - point at which the driving noise starts and the idle noise subsides
 +  - point at which only the driving noise can be heard at full volume
 +
 +An exemplary call to this function:
 +<code lua>
 +soundeffectsutil.makeRoadVehicle2({ .05, .1, .3 }, .075, .6, .4, input.speed01),​
 +</​code>​
