With this update, the ability to select the spatializer in real time by pressing a key is introduced.
The implemented options are the following:
key "6" - Unity's basic spatializer
key "7" - Steam Audio
key "8" - Google Resonance
key "9" - Atmoki
key "0" - MichelSpaz, a spatializer that I programmed from scratch based on physical calculations of how sound reaches the ears, which I later modified to obtain a more artistic than real effect.
