Welcome to the music lab!

Collection of various tools related to sound in any form - from pure physics to the music theory. Let's experiment, discover, learn and have big fun.


Digital oscilloscope in your web browser. This tool enables to observe of the acoustic waveform read from the microphone (waveform).

Do you know, that...?

  • Oscilloscopes are used to observe the change of electrical signal over time.
  • In 1897 german physicist K.F.Braun engineered the first oscilloscope.
  • Osciloscopes are used not only in the audio (music) industry, but also science laboratories, hospitals and clinics.
  • Some artists use oscilloscope waveforms to make certain patterns. They are able to create eye-catching mandalas or floral shapes.
  • The first of real time computer games was made for oscilloscope. "Tennis for two" was programmed by William Higinbotham in 1958. Boredom is the mother of invention. is a website where you can explore the enchating world of sounds and compositions. The site is divided into modules and categories which refers to diffrent aspects of sound world. Here you can find easy and useful tools for musicans (online guitar tuner) or get to know how to play chords that may seem difficult to play at first. You can also familiaraze with concepts of musical theory. If you are into technical issues, there is also a subpage about contruction of various musical instruments and how various sounds are generated. How about seeing graph of your own voice scale on oscillscope or spectrum analyzer? Take your time to discover things that you haven't known about music before. Listen carefully and enjoy!
