This introductory guide also includes details on. Add Resonance Audio components to your scenes Resonance Audio components enhance the features of Unity's built-in audio components. For details on this enhanced functionality, see. Prerequisite: configure your Unity project to use Resonance Audio Configure your Unity project to use Resonance Audio for spatialized audio rendering. Add an audio listener to your scene Add a ResonanceAudioListener to your scene only if you are using the enhanced functionality that it adds to Unity's AudioListener. This component is not required in order to use other Resonance Audio components. It is also not required in order to use Resonance Audio for spatialized audio rendering. Typically, this is the Main Camera. Note that, this checkbox is only visible when you've configured your project to use the Resonance Audio spatializer plugin. Note that if you add a ResonanceAudioSource to a game object without adding an AudioSource first, Unity adds an AudioSource automatically to the google resonance audio object. This prefab has the required properties already set. A Unity AudioSource component is added automatically to the game object if it does not already have one. Note google resonance audio, this checkbox is only visible when you've configured your project to use the Resonance Audio spatializer plugin. You should hear the new soundfield played back. This prefab has the required properties already set. A yellow rectangular appears in the Scene view, showing the adjusted room boundaries. See for more details on configuring room effects. Add a reverb probe to your scene See. Room effects in Unity Room effects can be configured in the ResonanceAudioRoom script component. Adjust the following parameters to achieve realistic environmental audio for your scenes. Surface materials You can assign an acoustic surface material to each of the six Google resonance audio Audio Room acoustic surfaces. Use the surface's drop-downs to select surface materials. Each of the acoustic materials defines different degrees of absorption or reflectivity at different frequencies. For example, Heavy Curtain absorbs most high frequencies, giving rooms a dryer, warmer, sound. Polished Concrete reflects more sound energy at all frequencies, resulting in much brighter and more echoic room characteristics. Reflectivity This parameter lets you control the strength of early reflections in a Resonance Audio Room, giving your users an impression of the size and shape of the room around them. For example, you can reduce the value of this parameter to simulate the sounds of tightly confined small spaces. Reverb properties Three parameters affect late reverberation in the Resonance Audio Room: Reverb Gain This parameter lets you adjust room effects' loudness, compared to direct sound coming from Resonance Audio sources in a scene. Reverb Brightness This parameter lets you balance the amount google resonance audio low or high frequencies in your reverb. Resonance Audio Room effects do this by providing different reverb decay rates at different frequencies, just like in real rooms. You can use this parameter to adjust how full a room sounds. For example, reduce reverb brightness to give the impression that a room is fuller and simulate the sounds of a room containing many objects or people. Reverb Time This parameter lets you increase or decrease reverb length. The value is a multiplier on the reverb time calculated from the surface materials and room dimensions that you specify for the Resonance Audio Room. You can use this parameter to make acoustic adjustments to the size of the simulated room. Room size Use the X, Y, and Z parameters to set the dimensions of a Resonance Audio Room in meters. Room Size dimensions affect room sound and set boundaries that, when crossed, trigger the room effects to toggle on and off or transition smoothly from one Resonance Audio Room to another. Reverb baking tools in Unity Geometry-based reverb baking enables highly realistic reverbs by ray-tracing against static scene geometry. This reverb feature complements the Resonance Audio Room, which models only box-shaped rooms but can be reconfigured during runtime. In this scene, they are preloaded with results. Each probe has a shape of a sphere or a box. When a listener enters the shape, its baked reverb is applied. You should hear the player clapping their hands. Create a reverb probe A reverb probe defines a location where reverb properties are computed or sampled. The properties are baked using ray-tracing to simulate sound waves interacting with the environment. You can define a reverb probe's region of application. This is the region where baked reverb is applied when the Resonance Audio Listener enters it. You can create and configure a new probe or create additional probes by duplicating and modifying an existing one. Then, use one of the following options to add a ResonanceAudioReverbProbe. The box represents the reverb probe's region of application. In general, the more the reverb is expected to vary spatially, google resonance audio more probes are needed. Google resonance audio corresponding magenta-colored wireframe appears in the scene google resonance audio. Controlling when reverb probes are active Use the reverb probe's Only When Visible checkbox to avoid enabling a reverb probe when the player enters the probe's region of application but does not have a clear line of sight to the probe. This can be helpful in cases where the simple box or sphere shape of the region of application does not match well with actual scene geometries. For example, the spherical region of application for Cathedral Sanctuary Reverb Probe does not fit perfectly to the building. If the listener the white camera icon below is outside the building but inside the spherical region, the reverb inside the building is applied. This might not be the desired effect. If you enable Only When Visible, the listener no longer hears the reverb baked in the Cathedral Sanctuary Reverb Probe, even when the listener is inside its region of application. Understanding overlapping reverb probes When the listener is inside the shapes defined by several reverb probes, the most recently entered probe is used. In the following example, the listener was originally in Probe 1, then entered Probe 3, and finally crossed the boundary between Probe 3 and 2. The google resonance audio is in an overlapping application region of all three probes, but only reverb baked in Probe 2 is applied. Map visual materials to acoustic materials Support for mapping visual materials to acoustic materials assumes that objects that look alike should sound alike. If this is not the case for your project, consider separating one visual material into several. Then, map each of these visual materials to its own acoustic material. An asset is selected and the material mappings are shown in the Inspector window. All visual materials and the terrain used in the scene are listed in the lefthand column. google resonance audio Select Visualize Mode in the Reverb Baking window to see the mapped acoustic materials in the scene view. In the Reverb Baking window, select the newly created material map asset to load and modify the mappings. Include only specific game objects in reverb computations In some cases, you cannot include every geometry in reverb computations for your scene. Included objects reflect sound based on their mapped acoustic materials. Toggle non-static game objects Reverbs are precomputed and cannot change in runtime. For this reason, you might not want to include non-static objects, such as a moving character, in reverb computations. Last updated February 21, 2018.
