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.

Spectral analyzer

Spectral analyzer online. This tool allows to see audio signals splitted into frequency bandwidthes.

FFT size

Do you know, that...?

  • Following the discovery of fast Fourier transform, in 1962 the first spectrum analyzer was engineered.
  • There are two types of spectrum analyzers: swept-tuned and time-sequence.
  • Nowadays there are many kinds of spectrum analyzers: stationary, portable, handhled and networked.
  • Key attributes of networked spectrum analyzers include the ability of synchronize data captures and effortless free acces.
  • Use of spectrum analyzer provides a plot and trace of signal amplitude in the frequency domain. 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!
