The audio spectrum analyzer was made and operated stably, meets requirements for professional audio spectrum analyzer. However, display is not showed the sense of beauty because using LEDs, if we use LCD display matrix, it will make better result. If we combine the audio spectrumanalyzer with a tone equalizers, we will have a Graphic Equalizer.

The light bar is using an Arduino with a Vu shield to control the LEDs. The LDP8806 LEDs are individually addressable so they can make some nifty patterns. The audio is fed directly through an audio cable coming from the PC. The frequency of the audio is converted to data through an FFT library which tells the lights how to behave.

The audio frequency spectrum analyzer has to cover the 0 – 20000Hz frequency band. The spectrogram is displayed in 20- bar graphs. Each bar graph displays the total signal power level in a specific spectral band. As such, there are 20 spectral bands and we need 20 band-pass filters. Each bar graph consists of 20 LEDs
