Tracktion demo songs slow @96khz (fix'd)+ Montana is a troll

[No1234]

For instance if play back a 44.1k clip at 96k it uses much more CPU than playing back a 96k sample at 96k.
Presumably this is due to the resampling it's doing, which if you're interested is part of JUCE so you can see the code. It's a five point linear interpolation, which isn't especially optomised. If this is the same code that's doing the pitch shifting it probably explains why people are always complatining about that!

Thanks Kit I did think about the 44k samples in the demo songs, which is probably what is causing the cpu problems - along with denomalisation, and I also suspect that some of the synths and/or may not be used to working at 96khz? Just a suspicion -
What I think I will do is run some tests with cubase sx2 vs tracktion using 96khz recordings and an mda compressor or delay, and see what the differences are-

Now...regarding the system specs, I see no reason why Tracktion should not work very smoothly on your system matt_bentley.
Have you yet discovered the problem?

Yip - see above- still want to run some comparative tests though-

[No1234]

not quite:

when doubling the sample rate, did you also double the ASIO buffer size? If not, you are not comparing like for like.

When you double processor rate, you are doubling the rate that the ASIO buffer is emptied. This means that function calls to each VST (which are heavy on the CPU, and blow the CPU cache) will be happening twice as often.

Thanks for the input valley.
My motu unit's software automatically doubles the buffer, which updates in tracktion (somehow ) so yes, comparing like for like - BTW does that mean if I double the ASIO buffer I decrease cpu time at the same time as increasing latency, as is the case with most sound buffering systems???

You're a moron - I said thank you several times. I know more than you about this, obviously, because setting up with data on one drive and host on the other only makes a smallish difference in loading times _if_ you have a large number of files - setting up your virtual mem on another drive _Only_ makes a difference if you end up using a lot of virtual mem - which I don't. And it sure as hell doesn't make a difference to pure cpu processing times (which is the issue I'll remind you), unless the drive is horribly defragmented and has to search for large data chunks. So F*ck off and take your opinions to another thread - perhaps a 'lets all bash matt' thread - ""


lol. You know jack shit, kid. The next time you have an Operator Head Space Problem, dont be condescending to people who offer you help.
Let me guess, your parents bought you all the console systems and every game all the time, right?

And if you think a p4 2.4 is "very fast" you are on a very high dose of some kind of hallucinogenec drug.

you gota hand it to him this kid just dont quit

it does? that's smart! most don't which tends to catch people out.

cput time? do you mean load? If so, within a certain range, yes. My experience thus far is that setting the buffer size below 5ms at 44k has a noticeable hit on cpu load, whereas above that I notice little difference.

I've heard (not seen) that with Athlon64s the faster memory access makes lower latencies possible before cache flushing effects come into play.

Maybe soon my wife will let me buy one to find out.

I'm a complete and utter prick

Montana, its quite obvious to me that your posts in this thread are not intended to help anyone, but merely to make you look clever. (Didn't work I'm afraid)

Perhaps you have some self-confidence issues?

PLatinum - I only wrote a newbie guide for the original poster. Go back and read the thread. Im quite sure you learned something as well.

[d2]

You did no such thing, Montana. Instead, you posted a bunch of general tips available to everyone from a variety of sources ... nothing new, nothing original, nothing truly helpful ... just pithy little "I saw this on The Screen Savers" quips like:

3. Keep as much shit off your desktop as possible. Dont be one of these guys with 300 AOL shortcuts all over your desktop.

None of it seems intended to help, only to insult or to show off your "oh so special" technical knowledge.

This isn't an abberation, it's your M.O. ... and it's getting tired. Nobody is amused, and you aren't helping anyone or anything but your own twisted ego.

"Get a life" comes to mind.

Now post something else self-aggrandizing and insulting ... you know you can't help it!

[IIRs]

Yup. I learnt to ignore any Montana posts in future..

Nothing new or original? Are we at the Art museum or talking PC's? lol. Of course there isnt much new or original about maintaining PC's.

And as far as not being helpful, I got a few IM's thanking me for taking the time to write that short post out.

And admit you didnt even know how to turn off Auto Updates properly... sadly, I doubt you will.

wtf?



Speaking of "help", how have you tried to figure out the original posters problems, asshole? At least I was on topic and trying to help.

[d2]

And admit you didnt even know how to turn off Auto Updates properly... sadly, I doubt you will.

Silly, you base this assumption on what, exactly?

For your edification, bozo, I'm a systems engineer with over 2-dozen technical certifications from IBM, Cisco, SCO, and others. I'm the guy they call out when some wannabe like you has screwed things up beyond all recognition.

Regarding your comment on why I didn't help, let's get one thing clear: YOU didn't help either, and that's evident to most people in this thread. Your "few IM's thanking me" is a bit of completely transparent posturing. I "didn't help" because the original poster was well on his way to finding his solution by the time I first read this thread. I don't need to bolster my own sense of significance by chiming in with "me too" comments.

But you DO take directions well ... managing to both compliment yourself and insult others in your latest post.

C'mon boy! Do it again! You know you want to.

That doesn't mean shit. Your job will be in Shri-Lanka next month.

Im Cisco cert as well as MS. They are all rather worthless accomplishments in reality, and hold little value.

no, I did help. That's why I was thanked. Are you really this much of an asshole?

You have added a ton to the topic of this thread. Congratulations.
