I like Audacity too. I use it sometimes on Linux and sometimes on
Windows XP. The programming team has done a great job at making it work
the same on different platforms. It has the ability to manipulate
several (many, actually) sounds at the same time and is handy for
putting together a final mix. I use it for this even if I've done sound
manipulation on original cuts using other programs; it is easy and
natural to position cuts relative to each other, fade them in/out, and
mix them together.
Not only is Audacity free, but it is free software so that you can
download the source code for the program (from the same sourceforge site
as the binaries). If you've ever been interested in how programs do what
they do --- or what the programs are actually doing to your sound ---
you can find out by looking at the source. It's been enough to make me
give up using most "effects" offered by sound editing program! As the
saying goes, "just because you can doesn't mean you should".
Two features that I've studied in Audacity are the sample-rate
conversion (which I find to be very good. Its seems to be a really slick
and reasonably good, higher speed version of the methods used in Erik
de Castro's "libsamplerate" library.) and the FFT filtering effect.
There's aspects of the FFT filtering that I've decided I can do slightly
better, but I wouldn't even have known that if I didn't have the source
available.
Best,
Steve P
