SpatialiseScene Notes
|
|
---------------------
|
|
This scene demonstrates a couple of methods for spatialising Pure Data patches
|
|
in Unity.
|
|
|
|
|
|
Working with Unity's default spatialisation
|
|
-------------------------------------------
|
|
|
|
This method makes use of Unity's default audio spatialisation framework. It is a
|
|
bit more involved than the alternative approach, but doesn't an external
|
|
spatial audio framework.
|
|
|
|
The first thing to note is that, by default, Unity only spatialises
|
|
AudioSources. It won't apply spatialisation to any other audio producing
|
|
Components (like LibPdInstance). In order to get around that limitation, we'll
|
|
need to cheat the system a bit.
|
|
|
|
After adding an AudioSource and LibPdInstance to a GameObject in your scene,
|
|
the steps you'll need to take to spatialise your PD patch are:
|
|
|
|
1.) Set the AudioSource's AudioClip to the included SpatialiserFix.wav file.
|
|
2.) Set the AudioSource to Play On Awake and Loop.
|
|
3.) Adjust the Spatial Blend slider to 1 (3D).
|
|
4.) In your PD patch, multiply the 2 outputs of an adc~ object by the output of
|
|
your patch before feeding it to the dac~ object.
|
|
|
|
This process will ensure that the spatialisation applied to the AudioSource gets
|
|
applied to the output of your patch. See FilteredNoise-ADC.pd for more
|
|
information.
|
|
|
|
|
|
Working with spatializer plugins
|
|
--------------------------------
|
|
|
|
Alternatively you can work with a custom spatialisation framework, using a
|
|
Spatializer Plugin. Spatializer Plugins make implementation a bit simpler, but
|
|
they do require you to import a spatialisation framework into your project. The
|
|
following example uses Steam Audio, but the steps are identical regardless of
|
|
which framework you use.
|
|
|
|
It should be noted that Spatializer Plugins are almost always intended for VR
|
|
(i.e. headphone) use. So this approach may not make sense if you're building a
|
|
project intended for speaker output.
|
|
|
|
For the project:
|
|
1.) Edit -> Project Settings... -> Audio.
|
|
2.) Set Spatializer Plugin to Steam Audio Spatializer.
|
|
|
|
For each Audio Source in the scene:
|
|
1.) Toggle 'Spatialize' and 'Spatialize Post Effect' on.
