One of the Switch’s unique features is the HD Rumble functionality of its controllers. Unlike normal rumble/vibration that’s found in most other controllers, the Switch’s HD Rumble is able to mimic the wave patterns of sounds. This allows developers to create some very immersive situations where the action on screen and the sounds coming from the game itself are almost completely mirrored in the form the HD Rumble wave patterns.
One might think that this probably isn’t the easiest feature to work with, especially seeing that the Switch is the only console that uses it. Yet, I’ve personally played a lot of games where the effects are clearly implemented. Turns out that developers don’t have to do much to include HD Rumble into their games, because a core part of the SDK for Switch already has that tool.
As revealed in a recent interview with Daylight Studios from Nintendo Soup, the tool in the SDK allows developers to simply take a regular audio file and convert it into HD Rumble patterns by means of the tool analyzing the waveforms of the sound.
This is some pretty neat tech, and it’s great that Nintendo found a way that allows developers to take advantage of it so effortlessly.
