I think we both mean the same, but I'd like to point out that an
analogue signal as such cannot be used in any software, it has to be
digitized first, which is done through the soundcard's A/D. Software, by
definition, has no concept of analogue signals.
FFT works with numbers, not with analogue curves. The computer which can
directly process analogue signals as such has yet to be invented.
Unless I have missed an extraordinary development in the computer world.
