The amplitude and frequency of a sound wave can be examined using a microphone and oscilloscope. By measuring the speed of sound we can apply the wave equation to determine its wavelength.

Using the inputs on a computer’s sound card is an old trick to fake a very simplistic, AC coupled, slow oscilloscope. You can get DC operation by desoldering a couple capacitors, but if the ...

If you own an oscilloscope, sooner or later the urge ... He figured the easiest and most accessible way to draw on the scope was with sound, so he whipped up a small application he calls ...

Arguably the technical differences between them are subtle, but when pushed to excess, they can all sound very ... frequently we see the wave on a device such as an oscilloscope If we take the ...
