Audioscope |
Sound never looked like this before!
Audioscope will strike the right note in your
classroom or lab when you turn it on for an in-depth look at the science of
sound. By capitalizing on current hardware technology, this program emulates
the basic functions of the oscilloscope and the audio spectrum analyzer.
These instruments have been staples in a variety of fields-from music and
engineering to physics, biology, and psychology-but it is only recently that
analysis capabilities have been transferred successfully to the computer
platform. |

You can experiment with a variety of sounds
and analyze the resulting audio waveforms using three different
high-resolution displays: real-time sonogram, spectrogram, and waveform
graphical display. Sound waves are converted to analog electrical signals
using the computer's microphone. The sound card then converts the signal to
a stream of digital data, which is used to generate the waveform mode.
Audioscope uses Fast Fourier Transform to rapidly compute the amplitude
and phase at predefined frequencies, generating the spectrogram mode.
Sonograms are comprised of multiple spectrograms that are color coded and
arranged by amplitude. An averaging feature lets you extract weaker sounds
from noise in order to fine-tune the experiment. Measuring cursors are
included for quantitative analysis.
Audioscope guarantees a fun and educational learning experience. You can
experiment with familiar sounds in real time, or you can play with the
program's sample music scale which showcases the trumpet, violin, and piano.
Audioscope also includes other intriguing demonstrations, available with
just the click of your mouse: biophysics of speech production, touch-tone
phone analysis, the effects of helium gas on speech, analysis of amplitude
modulated signals, and the principle of signal averaging. |

A High School Site
License allows you to load the software onto any computer in your high
school. A Lab Pack allows you to load the software on up to 10 computers.
Generally a high school would purchase a Site License and a college or
university would purchase one or more Lab Packs.
