The term often used is interpolation. There are different methods for
this that trade off between quality and speed. Linear interpolation is
probably the simplest (besides no interpolation :) There is cubic
interpolation and other more complex ones as well, each increases the
number of points used in approximating (interpolating) samples.

linuxsampler is currently in somewhat planning stage still, there is
some base code from the evo project though. If you want to check out a
synth that is already working (although with a more limited scope,
SoundFont 2 files only), FluidSynth is a cool project
(http://www.fluidsynth.org). My own project, Swami
(http://swami.sourceforge.net) acts as a front end for this synth, and
may be a front end for linuxsampler in the future.

As far as I know Ardour is mainly a multi track audio recorder with
support for things like LADSPA plugins and routing of audio via JACK. A
software synth, such as what linuxsampler aims to be, is in a different
category all together, but would work hand in hand with ardour (the
output of the synth could be routed via JACK to ardour for processing).
