This a brief demonstration on the construction of a machine gun sound, for an upcoming game mod I’m working on (WW1:Source).

As an exercise, I tried to create an approximation of the German MG 08/15 machine gun using the sounds of everyday objects, and minimal processing.

The aim was a percussive, hammer-like sound, with metallic elements, loud but short in duration (as it has to be repeated rapidly in-game.)

So, here goes:

1. We start from a short sample of a plastic water bottle being squashed (not very impressive on it’s own.)

2. Add a little distorted sample from the same source: mix

3. Next, I add the sound of a wooden brush handle hitting a glass tile, for a bit of percussive ‘click’: mix

4. Overlay a sample recorded by shaking a small metal box filled with screws, for that metallic/ammo element: mix

5. …and another one: mix

6. A sprinkling of white noise: mix

7. Now, I add the sound of my espresso machine handle being slammed down (part of this sample pack), for that percussive thump: mix

8. … and a bit of wooden door closing, to accentuate that: mix

9. Then, a couple of hand-muted cymbal strikes are thrown into the mix, for a bit of metallic “clank”: mix

10. Finally, a snippet of metallic tinkle from my box of screws, delayed by a few ms, and a little low-passed reverb tail: mix

11. Now for a bit of compression, bringing the level up by a few dB: mix

12. Getting there, but let’s make it more “boxy”. Low-pass EQ at 40Hz,and  a bit of boost around 500Hz: mix

Let’s check it in-game:

Not bad… Of course a better result can be obtained from the same source material with the use of heavier processing, but my aim here was to try and use recognisable, relatively unprocessed sounds.
