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

Tuning fork was invented by lute musician.

Highest note define the position of chord.

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

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

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

Laryngologists use tuning forks in 432Hz becouse that's the frequency human body transcribes the best.

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

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