This site remains available for anyone who
purchased XO Wave in the past.
However, please keep in mind that as discontinued software:

XO Wave: Package Components
XO Wave consists of several components, and it can be useful to know
what they are and how they work together. This is entirely
optional, though -- XO Wave normally manages all its components
invisible and automatically on your behalf. For advanced users,
however, it may be helpful to understand their roles.
On Mac OS X, all the components are contained in the "
application bundle, which can be run and quit just like any
other application. On Linux all the components are
installed in an
xowave directory, including an
xowave script which launches the application.
XOgui: User Interface
XOgui is XO Wave's user interface (also called the
"front end" or "GUI"). Written in Java, it handles all the visible
controls (including windows, buttons, and dialog boxes).
Under normal operation,
XOgui starts the XO Wave programs as needed; on
quit, it shuts down any other XO Wave components which haven't
already finished and shut themselves down. It is also possible
to install XO Wave such that the user manages the other
components manually. See our Advanced Installation Guide
for details. Note that Linux users will see
a process called
java in process listings, whereas Mac
OS X users will see
XOgui. As the master program,
the GUI reads and writes
.xo session files; it also reads
.ovrv files) created by
XOmux: XO Wave Audio Engine Server and Multiplexer
The XO Wave front end does not actually perform audio processing or
manipulate audio files itself. Instead it hands off all such
XOmux, which, in turn, creates
XOengines as needed. This architecture allows
considerable flexibility, including XOengines with different
capabilities, and running a
single copy of XO Wave on multiple machines.
XOengine: Audio Engine
The audio engine (also called the "back end") performs the actual
audio processing (playing sounds, applying effects, reading and
writing audio clips, etc.).
XOengine also handles
CD burning -- using Apple's APIs on Mac OS X, and via
cdrecord on Linux. It appears as
XOengine is also responsible
for most of the work done by
offline operations as
well, including burning CDs, building and saving
waveform overviews (
.ovrv files), and
exporting files (
.mp3 and possibly other formats with third-party support).
