I'm making sound effects for my game after being inspired by sci-fi games like Infinite Warfare.
I design my gun sounds by recording a drum thud and then I apply a slight distortion to it to make it sound "crispy". I then use my computer and audio editing software to overlay the sound with a copy of the thud but the second copy has more bass and is streched and echoed. I mix the 2 and then I create a single sine wave beep and add it to the mix. I then record the a metal stick striking a thin aluminum bar. I do this to add a metallic sound to the gun shot sound. Finally, I record an electrical hum and add it to the mix, after futher tweaking, I have a gun shot sound but it's not that convincing. What should I do to make it realistic?
