Re: trigger from stream

are you looking for something like this?

Oh my God! Yeah!!!

OK, there are few warnings I must pose.
First, the schematic outputs triggers that are delayed by exactly 1 buffer size (or more accurately a frame). The timing is correct relative to each other, but you will get different overall lag ...

Re: Stock EQ V2


Hmm... IMO, what I suggested should work with any type of multithreading system ... it's the mechanism that matters here.
Without some "gating" system you try to draw all those triggered frames (could be 1000's / second ... depends on implementation ofcourse) which usually leads to visible ...

Re: Stock EQ V2

Ruby seem to support multithreading so, is it possible to use this feature in drawing routine ... i.e. bypass incoming triggers until current frame is fully drawn ?
Ruby "seem" to support multithreading. Th threads in ruby are "fake" threads. As far as system is concerned, there is actually only 1 ...

Re: Stock EQ V2

I have done some tests and I wasn't able to get any noticeable improvement in performance. The main cost in performance seems to be drawing the display in the first place. The old version already needs to draw buffersize/2 number of gradients and draws each pixel exactly once, so it's optimal in ...

Re: Stock EQ V2

Hello guys,
The FFT analyser is from my early years in ruby. I can make it a bit more robust, and perhaps less CPU intensive if you're interested.

Re: Export full Top View Module as VST

Hi,
I recently download Flowstone and I've been messing around trying to make my own vst however when I go to try to export the vst to test it, it only gives me the option to export vst for individual audio schematics. How can I export my whole top view module as a vst so every schematic exports ...

Re: Freely Configurable Filter

I'm especially fascinated by the minimum phase response mode. I always knew that it should be possible to calculate minimum phase response for given magnitude curve and I've been hunting for such algorithm for years now... Do you by any chance have some references to what you've done there? I can ...

Re: C/C++ programmers, please confirm

1) enum is a list of specific integer values that are accessed by their name

Well, kind of but not really. Enum is only required to have implicit conversion to char and signed/unsigned integers. The actual specific underlying type is implementation specific (though all compilers happen to default ...
