REVERBS

(Please note that this page takes off the latest SVN builds of ZDoom. Although sound reverb is available in ZDoom 2.2.0, you will require an EAX compatible soundcard to use it)

Warning: The SNDEAX lump has been replaced with the REVERBS lump. All functionality is the same; the name was changed in order to properly convey that a soundcard with EAX support is no longer required to hear the reverb effects provided by the lump. WADs using the old SNDEAX lump will no longer function properly from this point on. It is recommended that you use the REVERBS lump in your projects instead.

About

REVERBS is used in zdoom to make realistic sound environments. The basic idea of reverb is to have echoes/re-pitched sounds in rooms to make them sound like what they actually are, like a cliff edge or warehouse. Previously, you needed an EAX compatible sound card to use reverb; however, in the latest Development builds, ZDoom uses FMOD Ex to handle reverb so you don't need anything special to hear the effects.

Switching underwater reverb on

To switch reverb on, go to the sound options in ZDoom, and switch on 'underwater water sound reverb'. This will switch on underwater reverb (For sectors using Transfer_Heights water). Underwater reverb is automatic, and doesn’t require any special behaviour in the maps for its use. You can also force the underwater reverb effect on in any area of your map by using Thing 9048 with its first two arguments set to 255. (See below)

Using reverb in your maps

To use reverb in your maps, you need to place the reverb thing (ThingID 9048) into your map, and then change its special proprieties. The first 2 values are used.

Because only one reverb can be used at a time, you may want to block off a reverb thing from taking over the whole map. To do this, border the area with lines set to Line_SetIdentification, with argument 2 set to 1.

If you set the reverb thing to inactive in your map editor, the reverb effect will not take effect immediately. You can then activate it via ACS to "turn on" the reverb effect. However, you cannot simply deactivate the thing to disable the reverb effect; instead, you must activate another one in the same area. If you want the reverb to turn off completely, you can add a reverb thing with its properties set to 0 0 (See below) and activate it when you'd like to disable all reverb effects.

An example map is found here: http://zdoom.org/files/examples/eax.zip

Defining a reverb environment

An environment definition takes a fancy name within strings and two numbers as identifiers, the number combination must be unique. The rest is a list of named parameters within curly braces.
