Compared to what the final release of 6.1 the beta is using at most 12% more of my cpu. I have an over clocked quad core, 3.2Ghz so it doesn't always cause problems. What I'm wondering is why the cpu usage is still at 5% even when ST isn't getting any audio information. What on earth is it processing, why is it processing, and can that be stopped?
12% more!? And you're NOT using the declipper or Natural Dynamics? Then it should be roughly identical to the released version 6.10...

I'm currently not checking for silence - that is indeed a useful optimization.

Hans, ever got any headway in multi-threading ST? You have a lot of things going on in ST now. I'm just wondering, I know its practically impossible with audio applications like ST since everything needs to be on time and can't be really "split".
I have some ideas, especially for the declipper (channels can be processed separately). But I'll look into that later - right now I have a big clipper (Loudness) redesign and a Multiband redesign planned.

8-)
Any progress in Declipper? I am asking because i'm waiting next from quote up. :)

@ Brian

A simple question:
Comparing your SSm4 with my IO2.3.16K, what Post Amp compensation value(s) do you use ?
What is built in with the preset, so with mine it is 0.99 and with yours it is 0.96. Everything else incoming and outgoing is exactly the same.

The difference is pretty much all Multiband. You can get my preset to sound similar to what you appear to like by changing it to LIMIT. That's the normal difference between limit and compress... There are a few finer details that make a difference still, like the upspeeds and EQ settings, and then a few differences in loudness, but the majority of difference is just limit vs. compress...

I was overpowering multiband, which is why some mids were getting squashed - there just wasn't enough room for them given the power I was pushing into both the lows and highs. I'm hoping with the multiband and clipper (loudness) changes Hans is talking about, I can get it to sound better. For now, I think I'm going to let 4.2 stand and just keep refining.

Hans , come to Greece on August.

free vacataions in Crete Island ( Greece ) from me!

Leif is gonna come in Thessaloniki ( Greece ) to get the DDS exciter :)
You come to Crete to get vacations :!!:!! ! ! :mrgreen: :mrgreen: :mrgreen:

of course you will have 1 GBps inernet connection for your work :) ( from the universiry ) or .. 23 MBps from my home :)

not kidding, come for vacations...but take your laptop :)

My mistake, I do have natural dynamics on and loudness on, but not the declipper. And I also said at idle its at 5% i meant 12 - 15%. Natural dynamics and the upsample setting in the loudness/limiter panel boost the CPU usage up a lot. From around 5-8% when they are off to 12 -15% when they are on. For clarification I have a Q66 Intel processor.

Do it, it'd help my situation a lot since I use ST on the computer which I use for everything else.

Just wondering, do you have the GUI thread and audio thread(s) separated?

@Bojcha: I'm finally starting to make some progress on the declipper. The whole week I've been trying to use image processing algorithms on a display of the waveform to detect certain features.... :shock: But in the end it doesn't seem to help much.

Now instead I just figured out a really simple filtering method to detect clipping. And this one often detects far LESS samples than the method I'm using so far, among others in DBN - Jack is Back, but not in the Metallica track :-)

So I'm now planning to use both methods and only consider samples as clipped if BOTH methods say that they are.

This won't fix everything, but at least for Jack is Back the result is much closer to the original. (Actually I'm now thinking that it might even be possible to combine the two methods in a smarter way, to improve things even further, but I'm not going to do that for version 6.20 anymore unless there are still tracks with issues after I've made this fix.)

@Gtxx: The GUI thread is in a separate thread. And for FM output, the FM Overdrive part is too.

@camclone: Thanks for the offer :-) But I don't think I can...
