Stereo Tool

Hans,

I can confirm this, even with a PC chrash the settings were saved (strange isn't it?)
I was at a local radio station yesterday demoing StereoTool (they want it on air ASAP) and they had an unstable machine when a trace alpha was inserted. Any way, after some time it just rebooted and everytime the settings were saved.

Things can be strange, when i switch off my ST processor, i have to just push the power button.
When i shutdown using [start] - [shutdown] in windows i get blue screen

I just talked with Hans, he thought i meant cutting the power from the pc.
But i just press the power button once so the pc shuts down. He will take a look at what's going wrong.

Ok, below 16kHz is not necessary.
I think input LPF should be set little bit higher than output LPF, maybe I'm wrong...

Pressing (short) power button on PC is exactly same as start>shutdown.. except if it's differently adjusted in power settings.. where you can, for example, set "suspend" for power button.
But, pressing and hold power button for 4-5sec turns OFF PC, exactly same as you pull power cable out.
In case 1, settings are all saved. ST (as any other program) closes normaly and saves what it needs to save.
In case 2, nothing is saved. - But in ST case depend what did you last with ST, You saved current preset in file or minimizing ST, it will save that state and with hard shutdown/restart it will boot just fine.

Maybe some automatic saving every defined time?

That with preset loading can be done bit different..
Like some remote small keybord with binded keys, so every key can mean something.

I do case 1. And it doesn't work.
You can try. Load a preset and close ST. Start ST again and everything is fine.
Next change Volume of soundcard. (Set it to 0.0%)
Press power button short. (Computers shuts down and turns off).
Press button again to start PC and start ST.
Volume of soundcard is not at 0.0% so that's wrong.
The same thing happens if i press start ->shutdown. Then the changes i made are also not saved.

Hans, I have difficult question, every band is processed at input sample rate e.g. 44,1kHz?

This is one of those times where it's all about the relative difference.

With what I reported yesterday, most of the writes using the old GUI took 1 second, with some taking 2 seconds, and very few taking 3 seconds. Given that, I needed to report up to 3 seconds. Now, I will admit that I have a substantially fragmented hard drive, but that is the case for both old and new. That could impact things, but I didn't mention it before because the old GUI still performs significantly better.

It also has little to no impact on CPU usage, as there are few disk operations on playback, but I am in the process of burning larger items to DVD so I can further defragment.

That indeed should be the case, and is why I disagree about saving changes in the DSP version when being sent to tray. In theory, Winamp should be told by the OS to unload, and Winamp should do its' normal unload process. I'll test that in a little while.

Edit: Tested. Was playing a track, and disabled Stereo Boost. With the GUI still up, I clicked Start -> Shutdown -> Restart. When the system had rebooted, went into Winamp and Stereo Boost was still disabled, so it wrote the change to disk during Winamp's normal unload process. Writing out changes when being sent to tray does indeed appear to be unnecessary for "I shut down without saving my changes" situations.

As for power outages, the only protection for that is an auto-save at a given time interval, but that only gives protection up to the resolution of the timer interval. With how slowly the save process works for me, I'd be highly opposed to implementing a forced auto-save, but I'd be OK if it was an optional function...

...although, I still maintain that being concerned about power failures is a contradictory point of view to preferring hard application lockups instead of gracefully handled exceptions.
