RAYA: Real-time Audio Engine Simulation In Quake 89

New submitter bziolko writes: RAYA is a realtime game audio engine that utilizes beamtracing to provide user with realistic audio auralization. All audio effects are computed based on the actual geometry of a given game level (video) as well as its acoustic properties (acoustic materials, air attenuation). The sound changes dynamically along with movement of the game character and sound sources, so the listener can feel as if they were right there — in the game.

    I liked what I heard, but I really like to have a demo of it to check out.

    Quake audio consists mostly of footsteps and bangs. This might be fun for, say, GTA IV/V, where the NPCs have conversations to which you can listen if you're close enough.

    Realistic sound has been around, as people point out, since the Aureal days. Now, to be honest, it should be baked into every engine and tied to your textures (soft textures absorb sound, shiny textures reflect sound, etc.).

    The fact that it isn't means a couple of things - it's too expensive (which I can't believe nowadays), it adds too much cost to development time (but surely modifying those sounds for echo etc. is more costly than just putting in a pure sound and letting the engine modify it as necessary),, people just don't notice that much, or the patent field is too heavy.

    Take things like TF2, HL, CS, etc. They are all same-engine. They are all 3D open environments. It is vital to know where shots etc. are coming from in order to play properly. But we don't see such audio tricks. That, to me, suggests they aren't necessary or certainly not the right value to waste time on.

    And, to be honest, I watched "ray-traced quake" over, what? Ten years ago? That tech still isn't used in modern games because of the above reasons. It's do-able but expensive, the development time is costly, the effect isn't that much different from pure cheating on the 3D drawing, and it's not in any of the major game engines. This is suggestive of the value of such things being minimal.

    And, to be honest, the realistic-"ness"of a game is the first few minutes of unboxing and then that's it. What destroys your immersion from then on is crappy plot, unrealistic capabilities, and AI that still - to this day - sucks. Fire gun, run around corner, wait for the idiots to pile round. The "better" ones might well throw a grenade but once you know that, you take account of that, and that's the AI beaten. To "win" the AI has to have reactions infinitely better than yours and outnumber/outgun you. Think about the average FPS game - there are several THOUSAND bad guys. And you. And though you might get stuck occasionally, you will win. You can use first-aid kits, they can't. You can lure them into traps, they can't (unless scripted). You can sit and wait them out. You can guess where they will walk next, they forget about you one second after they stop seeing you. It's ludicrous.

    Please stop wasting our game industry by reinventing tech we've had for decades and could put in any game, given time. Let's try and make a game with one, single, scary opponent (and maybe some NPC's to fill in the gaps). A Matrix-like game, for example. Agents are few and far between, maybe one per real player. There is only one that's a real threat. And there's you. And a world that you can both use to your advantage.

    When humans play humans you HAVE to have the same numbers on both sides. When humans play AI, you HAVE to be vastly outnumbered.

    I'd much rather Half-Life 3 had intelligent enemies who will choose to camp the chokepoints and not be lured out, than some fancy water effect or proper audio reflections or whatever.

    You're not telling me that with the CPU/GPU available nowadays, we couldn't make a Quake 1 opponent that - with the same programmed reaction times, capabilities, and facilities available to them as a human player - couldn't be a serious threat. I'd rather play that than yet-another "look how shiny" kind of game.
