AudioSpace calculates the amount of storage required for an audio
recording of a given duration for different sampling rates,
resolutions, and numbers of channels.  The calculation may be made for
uncompressed audio data or for several types of compression.  A
variety of units may be selected for reporting the result.

It is written in Tcl/Tk, which may not be installed by default on your
system. If it is not, don't worry. It is free and easy to obtain and
install.  The easiest way to obtain the Tcl/Tk environment you need is
to install the ActiveTcl
(http://www.activestate.com/Products/ActiveTcl) distribution from
ActiveState (http://www.activestate.com).  This distribution provides
the Tcl language, the Tk graphics library, and a bunch of
extensions. Don't be concerned by the fact that ActiveState is a
commercial outfit.  The Tcl/Tk distribution that they provide is free
as in both beer and speech.  They make their money selling services
and programming tools. The ActiveTcl distribution is currently
available for: GNU/Linux, HP-UX, AIX, Solaris, Mac OS X, and MS
Windows.

For FreeBSD, Tcl and Tk are available at:

If you install Tcl/Tk from some other source, note that in addition to
the Tcl interpreter and the Tk library AudioSpace makes use of the
math::bigfloat component of the tcllib library.

On a Unix-type system (including GNU/Linux, FreeBSD, OpenBSD, NetBSD,
Mac OS X, and SunOS/Solaris) just run the file as a shell script and
it will invoke wish, the Tcl/Tk interpreter, itself. You can also
invoke wish explicitly if you wish.  To install on a Unix system, it
should be sufficient to just to type make.

On MS Windows it may be necessary to associate the extension .tcl
with the Tcl interpreter.
