Fireworks came to us from China and dates back to 12th century when they were first used to frighten away evil spirits with their loud sound and also to pray for happiness and prosperity. This early fascination with their noise and color continues today during each great holiday, for festivals and other events in different countries around the world. Various colors and non-recurrent forms will definetely please your eyes!
This program is an audio analyzer with FFT and n-th octave frequency analyzers and oscilloscope. The octave analyzer can show the frequency spectrum at 12th, 6th, 3rd and full octave resolution. (A standard license supports all resolutions). With the FFT frequency analyzer you can see the spectrum on a linear scale, which can be useful for harmonics and other analysis tasks. Also on board is a real time oscilloscope.
