And when I take one signal (the left one for example) out of a stereo signal, would that be mono, but not true mono?
A mono input (with no subsequent FX processing) remains a true mono signal regardless if it is a single (mono) or two-channel (dual-mono) signal.
Conceptually what defines a stereo or mono signal is if the L/R channels play identical (mono) or different (stereo) waveforms.
It does not matter how you convert a mono signal to a mono-format audio file, it will always be mono.
The manual explains what the Mixer is doing re Mono/Stereo ...
Panning - Pan controls the position of the sound in the stereo field (left to right) and is often overlooked as a control for creating an interesting and spacious mix. The pan works by mixing one side of the stereo track into the other, so a 100% pan is the mono-sum of the Left and Right channels. If you would like to pan using independent Left & Right level changes with no cross channel mixing use Fruity Stereo Shaper. By default a 'Circular Panning Law' is used.
The important question is why does it matter and what are you trying to achieve?
