@ Hans
And here is another thing that might help to figure out how to create a better oscilloscope:
Try the free SignalAnalyzer VST plugin from rs-met.com
http://www.rs-met.com/freebies.html
It has two basic modes:
Signal (oscilloscope type)
and
Spectrum (frequencies)
In signal mode (sync: free running) and horizontal display set to 5 ms it behaves almost in the same way as Stereo Tool's oscilloscope.
If you then enable sync: lowpass zeros it already looks more stable.
Though I personally would prefer a slow waveform drawing instead of an oscilloscope.
Something like we see when we set the rs-met SignalAnalyzer's horizontal display to 1.5 seconds (and sync: free running !).
Drawing waveforms give more visual information than every traditional oscilloscope or meter can do.
When I use instead of the DSP an older (one of the betas <10, that work without crashing the Acon chainer) Stereo Tool VST version and sandwiching this with one instance of SignalAnalyzer pre and another instance post Stereo Tool VST (using display:signal, sync: free running and 1.5 seconds) these waveforms (Stereo Tool's input versus output) are very impressive.
It gives much better visual control about the whole processing.
(Ah, I had forgotton, that I have another free wrapper. This is an odd VST plugin that can host Winamp DSPs. So I will try this later to host the latest Stereo Tool Beta DSP version with this wrapper to integrate Stereo Tool in the Acon VST chain.).
So IMO the main problem with Stereo Tool's oscilloscope is: it is too fast !
I guess that the oscilloscope window in Stereo Tool's GUI shows more or less 5 ms ?
So first thing I would try, is to slow it down to 1500 ms range and see what will happen.
Or maybe another hidden setting for expert users inside .sts ?
OscilloscopeDisplayTimeRange=nnnn ms
EDIT
There were some mistakes.
I wrote micro seconds, but milliseconds (ms) were meant.
Sorry !
Maybe I was a little bit hypnotized by Stereo Tool's oscilloscope (too fast for my eyes and my brain).
