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.

Sound processing

The modules included in this section have in common the fact that they gather sound from a microphone or other enabled audio sources. Sound captured this way is processed in accordance with the specificity of the module. Tools such as an oscilloscope or a spectrum analyzer can be found here. Before you start browsing this category, make sure that your microphone is connected.

Guitar tuner

Universal instrumental tuner. It's designed to tune instruments like guitar o violin in chromatic scale.


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

Spectral analyzer

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