public static void DilateTexture()
    if (Selection.activeObject == null)
        if (EditorUtility.DisplayDialog("Error Selection", "Select a texture", "OK"))

  • Create a MonoBehaviour script with an OnAudioFilterRead method
    // write the incoming audio to the output string
    void OnAudioFilterRead(float[] data, int channels)
