When you make a sound, you are generating a vibration. That vibration then travels through the air and makes the microphone in your computer vibrate. An oscilloscope allows you to see how the microphone is moving. The movement of the microphone reflects the shape of the sound wave (also called waveform).
This oscilloscope also allows you to record and amplify sounds, and make them repeat in loops, generating rhythms and fascinating musical effects. Make sure that you allow the website to use the microphone.
Note: This tool works well on computers. Future versions will be available for iPad. This version is under development, so all suggestions are very welcome (Contact us).
