  • How Audio Design Enhances Diablo 2

    [01.09.20]
    - David Craddock
  • The following excerpt comes from author David L. Craddock's Stay Awhile and Listen: Book II - Heaven, Hell, and Secret Cow Levels, available for pre-order on Amazon Kindle ahead of its December 10, 2019 publication date.


    SCOTT PETERSEN AND Matt Uelmen rooted through stacks of CD-ROMs. Each disc was filled to capacity with yells, screams, groans, moans, thuds, grunts, slices, cracks, smacks, scrapes, scratches. They had thousands of sounds at their disposal, but when nothing pre-recorded would do, they turned to instruments and technology: drums, guitars, synthesizers, and computers loaded with cutting-edge recording and mixing software.

    In this case, nothing they had on hand would do. They walked to the supermarket down the street and loaded shopping carts with melons and vegetables. Back at the office, they wrapped produce in saran wrap, turned on their microphones, and destroyed their groceries. The meaty yet hollow sound of a watermelon exploding was, in Scott's mind, exactly how a zombie skull would sound as it was caved in.

    It's more like a movie set where you need to create the entire sound environment instead of letting it follow naturally from the world's architecture. You need to place each sound where you want it to be heard. -Jon Stone, programmer, Diablo II

    "That was the basis for almost all of the melee damage sounds for Diablo II. It was a blast. You just find yourself getting maniacal because the process of recording is a lot like a performance. You try to get the right sound out of the object. That's sort of a musical experience whether it's a drum, or a chunk of wood, or you're hacking and slashing on a turkey carcass, which is one of the things we had-you just try and put your best effort into it so you get the best recording out of it. It was kind of intense there for a little while."

    "Working with Scott and Jonathan was amazing," Matt Uelmen agreed. "I was incredibly lucky to have that experience. Our backgrounds just meshed extremely well: two out of three of us had a rock music background, two out of three had some training as composers, two out of three of us had a strong technical audio background, so the combination was really magic."

    A programmer able to carry-or at least code-a tune, Jonathan Stone rounded out Matt's audio team. Matt and Scott served as Diablo II's dedicated sound designers, creating the effects and tracks that would punctuate the player's journey through Diablo II. Jon's task was to layer those sounds into an aural environment.

    "It's more like a movie set where you need to create the entire sound environment instead of letting it follow naturally from the world's architecture," Jon explained. "You need to place each sound where you want it to be heard."


    The original Diablo served as Jon's inspiration as well as his impetus for improvement. He admired what Uelmen had done in the first game, but noted-and Uelmen tended to agree-that the game lacked aural variety in each scene. There were six main tracks: the title theme, Tristram's motif, and a track for each of the four dungeon environments. Jon, Scott, and Matt were united in wanting to deepen those arrangements and diversify sound effects. For instance, in Diablo II, the smack of a Fallen's club against a hero wearing leather armor sounds different than if that same club strikes a hero wearing chainmail.

    "That was something we talked about quite a bit," Jon explained. "Little sonic layers that could reinforce the reality of the objects in the world. A lot of time was spent in crafting small details like that. While any particular one didn't have a dramatic effect on the game, when taken together, I think they really made Diablo II sound much richer than Diablo."

    Game feedback began with a click and culminated in the appearance of treasure: click, click, kill, click, click, kill, click-loot. Matt stressed to Scott and Jon that they should design sounds according to the action happening on-screen. Every now and then, he'd pick up his guitar and strum a dramatic chord while singing "Kill the monster, kill the monster."

    "It goes back to that whole idea of being as clear as possible," Scott explained. "I was obsessed with getting the right sound for the right moment." He fixated on one effect in particular, the telltale ding of a gem falling from a defeated enemy. He created the sound by purchasing dozens of wine glasses and tapping objects against them until he hit on just the right note.

    Unless you put in something that's really, really bad, you just don't hear too much about it. People don't have opinions about sound. They have opinions about a color, but not sound. -Scott Petersen, audio designer, Diablo II

    The result of creating homemade sound effects by combining everyday items is known as Foley, named after sound artist Jack Foley's technique of creating sounds from everyday objects and matching them to film. When Foley wasn't needed, Scott would comb through archives of pre-recorded effects. "I took it upon myself to really work on the combat system defining how an arrow sounds when it impacts and does damage to a creature versus when it ricochets, or glances, or doesn't do damage, and just applying that system to all the different character classes for all the melee, and doing that for all the spells, et cetera."
