The Output Model acts as a template which defines playback output parameters for any sound or set of sounds. You can set up a sound to act as a mono point-source sound using HRTF (head-related transfer function) for proper placement relative to the camera/listener, or as a stereo sound with radius or no radius (i.e. no apparent position), or even with specific speaker assignments and levels in mono, stereo, or surround formats.

* '''ID:''' unique description of the output model
* '''Uses HRTF''' select this if the sound is mono and will be played back as a point-source sound in the world relative to the listener. This will grey out the configuration options for Defined Speaker Output.
* '''Defined Speaker Output''' select this if the sound will not be placed in the world but rather have a specifically defined playback through various channel setups. You can define data for Mono, Stereo Left, and Stereo Right inputs, using the "Source Input Channels" and "Input Channel" widgets to select which input you want to edit.
** '''Source Input Channels''' is used to choose whether to edit Mono or Stereo channels.
** '''Input Channel''' is used to choose which channel to edit (i.e. if Source Input Channels is 2, for Stereo, then this lets you pick channel 0 for Left or 1 for Right).
** '''(channel outputs and output percentages):''' Data for the currently selected input channel. L - Left, C - Center, R - Right, RL - Surround Left, RR - Surround Right, BL - Rear Surround Left, BR - Rear Surround Right, LFE - Low Frequence Effects. % of output is defined from 0 to 100 percent.
* '''Attenuates With Distance''' select this checkbox if the sound should have an inner and outer radius setting, using a volume falloff curve between those two values.
* '''Min Distance''' inner radius of the sound in game units. At and within this radius, the sound will play back at its max volume (its static attenuation as set in the Sound Descriptor). Between the inner radius and outer radius volume falls off according to a five-point curve as defined below.
* '''Max Distance''' outer radius of the sound. At the outer radius, the sound's volume is fully attenuated.
* '''Curve''' the custom volume falloff curve between the sound's inner and outer radius (min and max distance). The top-most slider is the data point at the inner radius, whereas the bottom-most slider is the data point at the outer radius. Typically values might follow a slightly logarithmic falloff curve (from top to bottom: 100, 60, 30, 15, 0) or linear falloff curve (100, 75, 50, 25, 0), or any configuration as needed.
* '''Reverb Send%''' percentage of the sound sent to the Reverb Parameter as defined in the currently occupied Acoustic Space. This is equivalent to an 'aux send' on a mixing console. Any sound assigned to use this Output Model will be sending this percentage of its output to the current reverb type.
* '''Allows Rumble''' check this box if the sound should use the Rumble settings as defined in the Sound Descriptor
