It's not specific to linux, an UNIX-like system
will have something like that.

Yes. And perhaps a native recordin/playing application.

Please note that on many systems there is nothing to install.
Recoding and playing sound is largely considered a part of
general-purpose computing, so the system will already have
a tool that records/plays.

Just to rule out a misunderstanding: you don't "adjust"
your IP address; you machine has one.

Coming from windows, you might find it interesting that the two
separate pieces of that task (namely, recording/playing sound and
sending data accross a network) are performed by two separate
tools that have nothing to do with each other, and have no
knowledege they are working in such accord. In rec | nc,
rec has no idea where the recorded data goes, and nc has
no idea where the data came from (and that it is audio data);
each is just doing it's separate job.

Why is it actualy that you need to record on one computer
and play it out on another?
