The audio reactive components listen to the audio in your region (including music streams and audio clips), and can alter and animate objects, materials and lighting within the region in time with the audio stream.
To set up your scene in Unity for the audio reactive components, you need to first either drag an audio file from your PC into the project window, and then into the hierarchy, or for music streams, you need to (info).
This component can be attached to the 3D object you want to react to the music and then used to transform the 3D object in time to the audio.
You can transform the object within the component, so you can set the object to scale, rotate or move in certain directions.
Band Min and Band Max
There are different types of bands for the different frequencies in audio. For example, if you want the object to move to only the bass of the audio, you will need to set the band min slider to 0, and the band max to 1. You can play around with the different values until it matches the audio band you want the object to move to.
