Would I need a high powered audio card to do that?

You'd *want* one that sounds good, but I'm not quite sure
what you mean by "high powered". Unlike (say) video, two
track audio just doesn't require that much processing power
to simply record[1] or play back.

Arny Krueger has a nice list of good-quality audio cards he

http://www.pcavtech.com/soundcards/compare/index.htm

Some of the cards listed are a few years old, and there are
probably some newer cards not listed, but it might give you
some useful information anyway.

As for software, I haven't used it, there is a 30-day "tryout"
version of Adobe Audition available, and I *think* it should
be able to do everything you need based on the description
of which features are disabled (not many) in the trial version:

Hope that helps.

[1] The corollary is that all these super-deluxe consumer
sound cards that have been released over the last few years
rarely do anything that an SoundBlaster PCI128 doesn't do,
except maybe surround sound, which is just the addition of
a few more channels. Well, some of them do some 3D audio
effects, but most of those effects sound like crud to me.
Also, some of them do MIDI in hardware, but these days
MIDI can easily be done in software, so that's mostly
useless as well...
