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.
