Sure I know how to make sounds. I do however have a strange habit of doing all of my complex design in Sony Vegas...er Magix Vegas. Or whatever it is now. Basically, it's like Sound Forge on steroids. So if you like how Sound Forge works you'll really dig Vegas. It's got multitrack, proper signalflow routing, obviously works well with video, and has Sound Forge integration to bounce individual files back and forth.
Beyond that, my philosophy for sound design is all about appropriateness. Yeah, I shoot for using all of my own sounds, but if a library sound fits, and it's not terribly overused, then I'll use it. I think finding and manipulating externally sourced material is just as important as using your own custom sounds. The key here is how does it work together when married with visuals, gameplay?
No, I'm not designing sounds or integrating anything in this image. It's a picture of me at Daytona really super close to the bend capturing source material for games. At the time I think it was Tron Evolution.
At any rate, Sound Design and Integration for video games is the majority of what I do. I got a degree in it. It is fantastic. It is an art. It is a science. That is not a bib for food.
I've got a more current reel on my home page, but here's one I made a few years ago with me talking on it, so that is sure something that someone would click on, yes?
