GenAudio?

[gamerxxl12]

Is GenAudio just a gimmik or something to take seriously? I'm not to sure about their 4D audio technology

If anyone has experience with this can you tell me.

I think it's worth taking seriously, after that audio demo I was won over A LOT and after hearing examples of it in game it actually makes a really big difference.

Binural recording metods have been around for a long time, but has never been implamented into media on a wide scale. I hope GenAudio will be able to change this, since it would make for a very immersive listening experience. As always, time will tell if this is just another gimmik that will fade away.

well it's existed since 2004 so I don't think it's a gimmick.

It has existed since atleast since atleast 1999. I remember the first time I heard it was on the Pearl Jam album Binural, and that was recorded in 1999.

 

Gimmick was the wrong word to use there. What I meant to say is that this kind of recording has existed for a long time, and I hope that GenAudio will help bring it out to a wider audience. I hope they will not fade away like the other solutions before them.

 

Edit: According to Wikipedia the concept behind binural recordings has been around since 1881.

One thing is Binaural recording ( this video, nothing special ), and the other thing is sounds in games.

 

So. When you hear stuff, your brain does the work for you and it tells you where the sounds are coming from. Its called "Cetera algorithm" or something, according to "virtual haircut" video.

But when ingame, the computer has to calculate how to deliver sound to 2 headphone speakers in order to deliver position of the sound in game. It takes alot of processing power to deliver true binaural sound. Usually they just use crossfade and other tricks.

 

Whether they will at least come close to true binaural sound i dont have slightest idea. Doom 3 demo was dissapointing.

 

Recording a sound with 2 microphones, feet apart and then using software to put it into an mp3 is easy.

On the fly taking a position and calculating how to deliver  sound ( for example volume, timing, reverb, etc ) is extremelly gpu taxing. I think Palmer Lucky was talking about that when they had virtual reality meeting. Its on youtube, but i am too lazy to find it.

TrueAudio from AMD basically means that we don't have a performance hit from this which is pretty cool :3

That's amazing, I don't think I have heard of anything like this before, I think the only implementation I heard of it, which I guess was a "tech demo" was that virtual hairdresser one? It's awesome, Is it hard to engineer this kind of sound in post/production?

So there is a chip on the pcb designed to do that ? Sweet.

It's practically a co-processor (well more specifically a DSP) that handles all the audio processing.

25 years of sound research apparently.

[Guest GRRigger]

25 years whoa. well if only amd has the comodity ( for now ) of this tech, they got an ace in their pocket

still think nvidia should have it too.

AMD has put three Tensilica DSP cores on their R series dies.  These are not specific processors but are programmable DSP's that can do whatever you want them to.

 

Companies like genaudio are capitalizing on this "free" resource to process bin-aural sound.  What I would like to know is how does the Tensilica DSP perform next to the more populous DSPs like, cmedia, dolby, realtek, creative, etc etc.

 

Once audio tech vendors start producing multicore solutions the whole true audio will become as obsolete as disc drives.
