Borderlands 3 unique weapon sound design

Gearbox Software's Senior Sound Designer, Joshua Davidson,  revealed in an interview that Borderlands 3 has a lot more sound files than Borderlands 2. There is so much work to be done that Gearbox Software is outsourcing some of the work. Joshua revealed that they are already up to 7500 sounds files for all the weapons in Borderlands 3. To make a comparison, Borderlands 2 "only " had 300 sounds files for the weapon arsenal. This means that Borderlands 3 already has 25x more sound files for the guns. However, the different amount of sounds guns can make is much MUCH higher due to new tech.

Modular  Sound Design

Joshua did explain a bit about how they got to the already insane amount of weapon sounds. With Borderlands 2 the sound design team made custom sounds for each of the weapon manufacturers and their gun types. By layering various sound elements on top of each other they created unique sounds for the game. Now with Borderlands 3, the team is going for a modular approach and is breaking it down to sound elements.

A little while back the GBX sound design team did a project with Marshall McGee on how to make explosion sounds. In this video, you can learn about the various elements that are needed to make a good explosion sound.  With Borderlands 3  the sound design team is providing the game with all these elements and hands over the final mix-down to the game itself.

If you are familiar with the loot system in the Borderlands games, you know that guns are broken down in various parts. A Body, a grip, a sight, a barrel, and so on. Each weapon part has its own stats and abilities that impact the outcome of the gun. In the previous Borderlands games, these stats impacted the damage output, accuracy, fire rate, and reload speed. With Borderlands 3 these parts now also impact the sound of the weapon. Each part contains a layer of the gun sound. For example, the magazine can determine the type of gun sound because of the ammo, the body could impact the power of the sound due to the force it provides, and the barrel could affect the reverb.

Now when the game assembles the various parts to generate a weapon it will not only feel different but also sound different.   Dahl weaponry might have a  hard metallic clicking sound, while Hyperion weapons sound more smooth. Maliwan guns will probably have a sci-fi zooming sound and Vladof rifles a grinding sound.  The fire rate could be used as an offset on how quickly each element is mixed together.

Conclusion

The game is doing the sound design out of a huge audio library and is mixing it real-time instead of using pre-made weapon sounds. So instead of saying Borderlands 3 has 25 times the amount of gun sounds compared to Borderlands 2, it is looking more towards every gun is having its own unique sound. This will add another layer on top of the weapon system to make the guns feel more unique.

7500 sounds / 3 sound elements = 2500 sounds per element 
2500x2500x2500= 15,625,000,000 combinations

I wonder how this works with the guns that verbally abuse your enemies. Will they get different dialogue based on the weapons parts?
