How expensive it is to create your own AAA-level game audio solution?

Don’t be greedy, unless it’s really cheap I’ve been in the game industry for almost 5 years since I broke up with traditional music post-production, and the official direction which I spend every 8*5 (of course, sometimes more) hours a week and get paid is not surprisingly, game audio. It doesn’t matter how you’re familiar with this domain, more or less you’d hear about some names like FMOD or Wwise recent years, even you’re just coming from a typical gamer’s point of view. Nowadays anybody who struggles to pick up a sound acceleration card would be called a perfectionist, a rational mind would just spend some hundreds or thousands whatever-your-local-currency-it-is to get some decent speakers or headphones, and that’s ALL for gaming.
