# SoundVolumeGroup

SoundVolumeGroups are an easy way to control the volume of a group of SoundEvents

[SoundVolumeGroup](/docs/soundvolumegroup.md) objects are used for grouped live volume control of multiple [SoundEvents](/docs/soundevent.md).\
You can assign them in the [SoundEvent settings](/docs/soundevent.md#settings).\
It is perfect for quickly mixing the volume of a large group of sounds.\
It also supports +12dB volume if you “[Enable Volume Increase](/docs/soundmanager.md#settings)” in the [SoundManager](/docs/soundmanager.md).\
The volume is not meant to be changed at runtime in builds.\
If you want to control the volume in builds, take a look at the [TemplateSoundVolumeManager](https://sonity.gitbook.io/docs/pages/x5ioYp59iaMMelgNSm6F#templatesoundvolumemanager.cs) script.\
All [SoundVolumeGroup](/docs/soundvolumegroup.md) objects are multi-object editable.\
Example use: Add the same [SoundVolumeGroup](/docs/soundvolumegroup.md) to all e.g. gunshot [SoundEvents](/docs/soundevent.md) so you quickly can change their volumes.

### Sonity GUID

Sonity uses cached GUIDs for object comparison.\
This solves problems where object equality isn't always the same when using e.g. addressables.\
The Sonity AssetPostprocessor automatically saves the GUIDs for objects.\
If you have any missing GUIDs (when upgrading) you can run:\
"Tools/Sonity 🔊/Tools/Reserialize - All Sonity Assets".\
