Sound processing

You're here:

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.

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.

Oscilloscope

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.

Do you know, that...?

Following the discovery of fast Fourier transform, in 1962 the first spectrum analyzer was engineered.

Some artists use oscilloscope waveforms to make certain patterns. They are able to create eye-catching mandalas or floral shap...

Since 1939 binding sound for pitching musical instruments is in 440Hz frequency. Formerly it was 432Hz.

Three crossed turning forks are in Yamaha brand logo.

Tuning fork was invented by lute musician.

Oscilloscopes are used to observe the change of electrical signal over time.

In 1897 german physicist K.F.Braun engineered the first oscilloscope.

Drum sounds can't be compononents of a chord. Chords can only consist of certain notes.

There are two types of spectrum analyzers: swept-tuned and time-sequence.

Chords contain tierces (thirds).

Osciloscopes are used not only in the audio (music) industry, but also science laboratories, hospitals and clinics.

Key attributes of networked spectrum analyzers include the ability of synchronize data captures and effortless free acces.

The first of real time computer games was made for oscilloscope. "Tennis for two" was programmed by William Higinbotham in 1958....

Tuning fork is a tool used to pitch musical instruments.

There are two type of chords- consonant chords and disonant chords.

Nowadays there are many kinds of spectrum analyzers: stationary, portable, handhled and networked.

Musiclaboratory.net 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!
