I've found a workaround for the first issue - or rather 2 different workarounds.
1. A program called "Volume2" in which you can specify the audio device whose volume is controlled and choose how you want to controll it. (keyboard shortcuts, mouse wheel, etc.)
But my mouse has a second mouse wheel, which I use only for volume control.
The problem is, that I can't assign keyboard shortcuts to that second wheel. I can only choose from some presets - one of them is "volume control".
It reflects the volume control of the multimedia keys.
So I could use keyboard shortcuts or the main mouse wheel, but still not the second mouse wheel... Not a very satisfying solution.
2. (the better way) There is a way to controll the RME Total Mix app's main volume with the multimedia volume keys. (it makes the volume keys send vol up/down midi data to the RME Total Mix app)
Since the multimedia keys are - like mentioned - the same function as the "volume control" on my second mouse wheel, I can use it again.
(it makes no difference if control the main volume in the Windows mixer, or in the RME Total Mix app)
So only the second problem remains - the randomly appearing latency in Stereo Tool that requires restarting it.
Just looking for a way to make a desktop shortcut that ends and restarts a program, to make the process quicker...
Right now I didn't had the problem since 2 or 3 hours. I've downloaded an audio-video-sync test video to check it regularly.
I made some small changes in Stereo Tool's settings - for example increasing the normal output buffer from 0.015 to 0.02 sec.
Has someone an idea what can cause the latency going up to a whole second suddenly?
As long as the problem doesn't appear, the latency is absolutely acceptable for everyday use. (incl. watching movies in browser/player or playing games)
Just want to mention what an awesome program Stereo Tool is.
No pseudo-enhancements like many other sound enhancement tools do, that are mostly little more than overdone eq settings, or out-of-place reverb effects.
All of the presets are almost perfectly set. Just had to decrease some effects a bit here and there to not alter the sound too much.
AGC is the first volume controlling algorithm that I've ever heard that actually works. To me that's one of the greatest inventions since computers. Haha ^^
Seriously, you can get all your sound on about the same level, even with extreme volume differences, with almost zero pumping effects and with a reaction time that is hard to believe. Thank you very much for this great tool.
ps. I find AGC has more worth than all the other features together.
Well, not really, but you know what I mean. It's great that you include it in the free version. Still purchased the Basic with the awesome Declipper. Just the price tag for the Spectral Hole Filler is a bit too high for me. Still a subtle but noticable effect on some output. You don't make end-of-year sales by any chance?
