64-bit audio engines are on the way !

[arguru]

Like I say, 64-bit clearly makes a big difference on specific processes like reverbs.

Indeed, I signed 3 new billionaire record deals since I use 64-bit processing and mixing for my tracks.

But have you considered that you're hearing a big difference, BUT it's not linked to the 64bit version? Unless you programmed that reverb, you never know if the 64bit version isn't doing something else (on purpose or by mistake).

Although most reverbs imply filtering, I would have doubts about the benefits here too.

podium has had 64 bit mixer engine for ages

it's really not that neccessary though, but still it is annoying that poidum has had wider features than a lot of hosts but never gets much coverage here

That's a question for ArtsAcoustic to answer, its a simple 32/64bit button on the same plug. But I've noticed it on others too like the old Timeworks 4080L reverb (less noticeable on that one I might add, so perhaps there IS more going on under the artsacoustic hood so to speak). Doesn't require a particuarly long reverb time either.

Curiously, the 64-bit mode doesn't always sound better (read better as in subjective taste preference), but it is different on those reverbs.

'do you make money with music?'

I played piano in a Kansas City whore-house for 5 years-does that count?

I bet you spent more than you made

I STILL owe them guys money to this day! Hey!!!!

Do you know you can have in a FPU 80bit floatpoint number accuracy but 32 bit output? It's entirely possible with proper coding that 64 intermediate output is meaningless. It's also possible by using an apropriate algorithm to have as much bits as you want. It's only perfomance consideration. The same goes for memory adressing - you don't need 64bit registers to adres more than 2/4GB of memory. The 8086 has only 16 bit register yet it could adress 1MB. The 80286 (still 16bit cpu) can 16MB. Under 16bit DOS using protocols like EMS/XMS you could adress more memory.

For sure it's much more conveniet for a programmer to not resort to some workarounds but they exists and they can work.
(actually they were for many, many years...)

BTW. what level of headroom do have most profesional analog mixing consoles? If there is something to a good sound just big numbers (like max of 1.7976931348623157 x 10 ^ 308 for 64bit float) are not.

Just thought I'd post this again. I know arguing for the sake of arguing is probably what this post is really about, but if you wanted some facts..

[tony tony chopper]

marketing facts aren't facts

[ericj23]

the problem with that cakewalk page is it has NOTHING to do with 64 bit mixing - absolutely nil, nitch nada etc

thats about 64bit OS's - something completely different

well there's videos and articles on "64-Bit Double Precision Processing, Plug-ins, and Mixing", but that's indeed nothing new as outlined several times already in this thread. It can be done in 32-bit environment just as well (and has been done for god only knows how long).

The two concepts are interlinked somewhat, as processing doubles in 64-bit native OS is apparently more efficient at times (a few new instructions and registers in CPUs), which makes sense. The boost is there, but isn't that remarkable.

Hi guys, didn't read the whole thread, just came across this thread by accident...

When switching the AAR to 64 bit mode, nothing magic happens, just the whole internal process, to be more exact, the calculations are switched to 64 bit double precission floats.

So, the difference you hear is just the difference between 32 and 64 bit, nothing more. I was surprised myself, too, when I first checked it out. I did some tests, which parts of the algortihm were most affected, and from what I found I can say, that the most important thing is where summing plays a rule, and where lots of calculations happen. They seem to be much more precise in 64 bit, thus calculations are done more the way, the developer intended.

To find out more about AAR and 64 bit, also see here:

And of course, try it out (if you don't own AAR, take the demo version)

Podium is a sequencer? I thought it was some kind of crazy MC Escher experiment- Can't wait. M@

you mean you're not the developer?

[timo at artsacoustic]

Eh, no, not at all, sorry, english isn't my first language and sometimes things don't come over how they were intended... like 32 bit calculations

What I meant, to keep it very simple, is like: the developer (me) wants 1 + 1 to be calculated, the computer does it with the result 2.001... but what the developer (me) originally intended was 2.000.

Similar thing with 32 bit / 64 it calculations. 64 bit is more precise, less errors. Though the amount in a single calculation is very very small, it gets noticable, when lots of calculations (particulary iterations) have to be done and summed up - the errors sum up also. One has to keep in mind, a reverb does several billion multiplications and additions per second!

Hope, I expressed it clearer now

[tony tony chopper]

so you could tell if the precision mattered in summing parts or in filters?
