# Modifiers

Reference of all the modifiers available in the SoundEvent, SoundTrigger etc

<div align="left"><img src="https://3478075546-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FECYQ2OSoWTLdq4EUgnCW%2Fuploads%2FGadMTDgNLfDk1zHC0x9H%2FModifiers.gif?alt=media&amp;token=d47e3ff5-c014-471c-b5af-afcd22b5041f" alt="" width="501"></div>

[Modifiers](/docs/modifiers.md) are used to control how [SoundEvents](/docs/soundevent.md) are played (e.g. volume, polyphony, fade in length etc).\
They are available on the [SoundEvent](/docs/soundevent.md), [SoundTrigger](/docs/soundtrigger.md), [SoundPicker](/docs/soundpicker.md) and [SoundMix](/docs/soundmix.md) objects.\
They have similar functionality as the [SoundParameters](/docs/soundparameter.md), but with visual editing.\
Modifiers are only updated once when starting the [SoundEvent](/docs/soundevent.md), not continuously.

Some [modifiers](/docs/modifiers.md) use priorities to determine what a final [modifier](/docs/modifiers.md) value should be.\
The modifier with the highest priority will determine the value.

* 1st: [SoundParameter](/docs/soundparameter.md)
* 2nd: [SoundMix](/docs/soundmix.md)
* 3rd: [SoundTrigger](/docs/soundtrigger.md)/[SoundPicker](/docs/soundpicker.md)
* 4th: [SoundTag](/docs/soundtag.md)
* 5th: [SoundEvent](/docs/soundevent.md)

**Volume dB**\
Volume offset in decibel.\
Note that [modifiers](/docs/modifiers.md) are only updated once when starting the [SoundEvent](/docs/soundevent.md).\
If you want realtime volume settings for a loop, use the [SoundEvent](/docs/soundevent.md) base, timeline or [SoundContainer](/docs/soundcontainer.md) volume.

**Pitch st**\
Pitch offset in semitones.

**Delay**\
Increase the delay in seconds.

**Start Position**\
Sets the start position, 0 is the start, 1 is the end.\
The highest priority added [modifier](/docs/modifiers.md) will determine the value.

**Reverse**\
If enabled the AudioClip will be played backwards.\
Make sure to set the start position to the end.\
Reverse is only supported for AudioClips which are stored in an uncompressed format or will be decompressed at load time.\
The highest priority added [modifier](/docs/modifiers.md) will determine the value.

**Distance Scale**\
Distance scale multiplier (how far it will be heard).\
It is multiplied by the Distance Scale of the [SoundManager](/docs/soundmanager.md).

**Reverb Zone Mix dB**\
Reverb Zone Mix volume offset in decibel.

**Fade In Length**\
The length of the fade in.\
Is calculated using the time scale selected in the [SoundManager](/docs/soundmanager.md).\
The highest priority added [modifier](/docs/modifiers.md) will determine the value.

**Fade In Shape**\
Shape of the fade in\
Negative is exponential, 0 is linear, positive is logarithmic.\
The highest priority added [modifier](/docs/modifiers.md) will determine the value.

**Fade Out Length**\
The length of the fade out.\
Is calculated using the time scale selected in the [SoundManager](/docs/soundmanager.md).\
The highest priority added [modifier](/docs/modifiers.md) will determine the value.

**Fade Out Shape**\
Shape of the fade out\
Negative is exponential, 0 is linear, positive is logarithmic.\
The highest priority added [modifier](/docs/modifiers.md) will determine the value.

**Increase 2D**\
Makes the [SoundEvent](/docs/soundevent.md) more 2D (less spatialized).\
Useful for first person sounds.

**Stereo Pan**\
Stereo pan offset\
-1 is left, 0 is centered, +1 is right.

**Intensity**\
Multiplier of any used [SoundParameterIntensity](/docs/soundparameter/soundparameterintensity.md) parameter.

**Distortion Increase**\
Increases the distortion.\
Distortion needs to be enabled on the [SoundContainer](/docs/soundcontainer.md) for this to have any effect.

**Polyphony**\
How many instances of the [SoundEvent](/docs/soundevent.md) that can exist at the same transform.\
[Modifier](/docs/modifiers.md) polyphony overrides the [SoundEvents](/docs/soundevent.md) base Polyphony value.\
The highest priority added [modifier](/docs/modifiers.md) will determine the value.

**Follow Position**\
If the [SoundEvent](/docs/soundevent.md) should follow the given Transform position.\
The highest priority added [modifier](/docs/modifiers.md) will determine the value.

**Force 2D**\
If the [SoundEvent](/docs/soundevent.md) should be forced to 2D (no distance, no spatialization, no angle to stereo pan).\
Useful for Player sounds so you don't have to use Follow Position.\
This enables you to use the "[PlayOneShot Optimize](/docs/soundmanager.md#performance-settings)" for these player sounds.\
The highest priority added [modifier](/docs/modifiers.md) will determine the value.

**Bypass Reverb Zones**\
If enabled all reverb zones will be bypassed.\
The highest priority added [modifier](/docs/modifiers.md) will determine the value.

**Bypass Voice Effects**\
If enabled all voice effects (lowpass/highpass/distortion) will be bypassed.\
The highest priority added [modifier](/docs/modifiers.md) will determine the value.

**Bypass Listener Effects**\
If enabled all listener effects will be bypassed.\
The highest priority added [modifier](/docs/modifiers.md) will determine the value.
