## 選べる値

- Enum.RollOffMode.Inverse（0）：Volume attenuates from Sound.RollOffMinDistance in an inverse manner, mirroring how sounds attenuate in the real world. This is done through Sound.RollOffMinDistance/distance, where distance is the Vector3.Magnitude between the audio source and the audio listener.
- Enum.RollOffMode.Linear（1）：Volume attenuates between Sound.RollOffMinDistance and Sound.RollOffMaxDistance with a linear relationship. This is done through (Sound.RollOffMaxDistance/distance)/(Sound.RollOffMaxDistance-Sound.RollOffMinDistance), where distance is the Vector3.Magnitude between the audio source and the audio listener.
- Enum.RollOffMode.LinearSquare（2）：Volume attenuates between Sound.RollOffMinDistance and Sound.RollOffMaxDistance with a linear squared relationship. This is done through squaring Linear.
- Enum.RollOffMode.InverseTapered（3）：A hybrid model which follows the Inverse model when close to Sound.RollOffMinDistance and the LinearSquare model when close to Sound.RollOffMaxDistance. This is done by taking the lesser of Inverse and LinearSquare.
