# OVERVIEW
Client-side environmental reverb modifier.

# KEYS
- "radius" : Radius in units.
- "efx_file" : Name of the OpenAL EFX definiton to use.
- "roomtype" : Legacy enumeration for GoldSrc support. Please don't use this.

# NOTES
This works only with the OpenAL sound backend.

# TRIVIA
This entity was introduced in Half-Life (1998).
