Not long ago we were working on sound design for grenade launcher called the Thumper.
To get the right idea for the sound we started recording the sound of my voice while watching the animation of the weapon. From the recording, we have 2 parts of the sound. The first could be synthesized with a noise oscillator and the second with tonal waves.
