Tempus-3D

Description

The world, as we know it through our
senses, is constantly changing. Unfortu­nately, the world that we measure through
analysis is steady state. With few excep­tions, the tools we use to analyze the world
assume that the data being analyzed will
repeat in a regular fashion.

The Tempus software program is a step
toward true, high-definition time/frequency
analysis. It collects data by sampling, and
analyzes it by subjecting the data to
searches with a series of mathematical
filters scaled for frequency and temporally
shifted, or translated in time, across the
sampled data. The Tempus program ana­lyzes sound falling within a selected win­dow (typically 60 milliseconds wide), but
the analyzing filters have actually extend in
time before and after the analysis window,
giving the window “skirts.” Data from the
“skirts” contribute to the final results of the
analysis, particularly in the low frequen­cies. This approach is different from that of
the Fourier Transform, which only analyzes
the data points in the window. It also makes
possible the seamless analysis of a series of
sample windows, one placed immediately
after the other, with no loss in information.

Display of the results of the analysis is also
important, and it is here that the Tempus
program really shines. It is possible to
display the data, in full color, as a three
dimensional object that can be rotated in
space. The object can be drawn as a wire
frame object or as a complex surface.

With the new Tempus software, it is pos­sible to look at sound and see how the
amplitude, frequency, and time relate to
each other.

Computer Requirements

The Tempus software is designed to run
with Microsoft Windows
as its platform. You must have at least a 486
chip, though it is recommended you run
the program on a computer with a Pentium
chip with MMX. With this software, the
faster the computer, the better. You will
need at least 16 Megabytes of RAM—
though 32 is preferable—and 10 Megabytes
of free hard disk space. Your system needs
to be equipped with a sound card, and a
graphics accelerator designed for openGL is
highly recommended. Sixteen or 32 bit
color gives the best images, but 256 colors
will also work. The computer also needs to
be set to 800 x 600 resolution minimum
and small fonts.

Installation

Installing Tempus on your computer is easy.
Close all applications except possibly the
Windows Explorer. Before inserting disk 1,
note the serial number on the label. You
will need to enter this number while the
disk is in the drive. Insert disk 1 into the
drive. Either go to Run in the startup menu
and type in ‘A:\setup.exe’ or open the
‘setup.exe’ file from Windows Explorer.
After this step the installation wizard will
walk you through the rest of the process.
You will be asked to input the serial num­ber from disk 1. When the icons for the
program have been generated, they can be
moved to your desktop with the mouse.
Click on the TEMPUS icon, hold the left
button down and slide the icon to the place
on your desktop where you want it to be.
Close the small (now empty) startup win­dow by clicking on its “X”.
