@user2m\: btw, by "realtime-safe" I mean\: you worry about things like for
example, when the app does some memory allocations or garbage collection in the
audio thread when it shouldn't and it's hogging up the CPU for milliseconds,
which it leads to glitches or gaps in the audio output. With modern systems this
is usually not a big problem and maybe doesn't matter that much if it happens on
your desktop PC. But if you're a DJ or a musician performing through a mega-watt
PA, you don't want that! 😬
