I agree, the initially 'plastic' output of a simple sinewave generator can
be further improved for instance by adding more details as faint harmonics,
reverberation (using special FIR filters) or even by adding noise in order =
to
simulate a real-world microphone. Depending on the amount of time and money
you are willing to spend on such a project, it should be indeed possible to
create very realistic imitations.
Though, I would still continue recording truly natural sounds =96 just
prepared a relatively inexpensive set-up (a pair of Rode NT1-A microphones,=
a Tascam
US-122 USB audio interface and an old laptop) for my first attempts in
stereo recording.
