-     * The switch's rumble doesn't act like a traditional controller with two separate motors attached to
-     * different sized weights. Instead, the two values are like two sine waves that get added together.
-     * You can play around with different combinations here https://www.desmos.com/calculator/0lqas9aq89
-     * There's a fairly narrow frequency range around 100-250Hz that really shakes the controller,
-     * everything else is quite weak. To get a low frequency rumble, you can offset two frequencies
-     * by a target low rumble frequency, which gets you a very noticeable variation in amplitude.
-     * (It'll be much clearer if you click that link and play around a bit)
-     * I picked 0xA4 and 0x3E based on a sweep of values ~40hz apart, because they produced the least rattle
-     * in my controller. This may not extend to other Switch controllers, however.
