Graphic Equalizer Table
By Jose Lerma
![Page 2: Graphic Equalizer Table By Jose Lerma. Main Idea The main idea of this table is to display the frequencies of any sound or audio input, either by microphone.](https://reader034.fdocuments.net/reader034/viewer/2022042821/56649dc95503460f94abfd8e/html5/thumbnails/2.jpg)
Main IdeaThe main idea of this table is to display the frequencies of any sound or audio input, either by microphone or by AUX connection. Frequency is measured in Hz of which is displayed over a Frequency spectrum. Measuring frequency usually calls for Fourier transformer, but in order to do Fourier Calculations sound first has to pass through a analog to digital converter.

Main components
There are four main components to this project. These components are the audio input, AD converter, Fourier Transform, and the Displaying of the sound.

AD converterA analog to digital converter is a device that takes a continuous physical quantity and converts it to a digital number that represents the quantity amplitude. These conversions are done periodically, of which the result is a sequence of digital values. These values have been converted a continuous time and continuous amplitude analog signal to a discrete time and discrete amplitude digital signal. ADC is defined by its bandwidth, which is the signal to noise ratio. After this process is done the Fourier Transforms calculations can be done.

Fourier Transform
Fourier transformer is the mathematical transformation of signals between time domain and frequency domain. This can be simplified by calculations of a discrete set of complex amplitudes, which is called Fourier series coefficients

RGB Led TableThis sound or music will then be displayed on a RGB Led table which will show the range of frequencies. The table will have 31 columns of LED’s of which each column will be assigned to a certain range of frequencies. The max frequency detected will be 10 KHz. Lower frequency on the left and higher frequencies to the right.

Other Project Aspects
Other Aspect I would like to incorporate in this project would be to put a Proximity Sensing section on the table that would detect a user swipe. This swipe would turn the table on an off.

The Table View and Functionality
![Page 9: Graphic Equalizer Table By Jose Lerma. Main Idea The main idea of this table is to display the frequencies of any sound or audio input, either by microphone.](https://reader034.fdocuments.net/reader034/viewer/2022042821/56649dc95503460f94abfd8e/html5/thumbnails/9.jpg)
Graphic Equalizer Table View

On Indicator Sleep Indicator
The green light indicates when the table is currently on and in use.The red light indicates when the table is currently in sleep mode and not in use, but the table is still on.
On and Sleep Mode Indicator

Microphone AUX hookup
There will be two types of functions the display music.1. A Microphone that will catch any sound made around the table2. AUX that will display
Audio Hook ups
![Page 12: Graphic Equalizer Table By Jose Lerma. Main Idea The main idea of this table is to display the frequencies of any sound or audio input, either by microphone.](https://reader034.fdocuments.net/reader034/viewer/2022042821/56649dc95503460f94abfd8e/html5/thumbnails/12.jpg)
There will also be a proximity sensing section on the table that turns the table on and into sleep mode. The table will automatically be in sleep mode when the table is on, but when you wave your hand over the proximity sensor the table will than get out of sleep mode. This will turn the green light on in the top corner. AnotherIndicator that the table is on will be a flash of the table when the table turns from Sleep mode to on. In order to turn the table back to sleep mode the user will wavehand over proximity sensor.

The Main section will consist of 12 LED high by 31 LED wide. Each columnwill display a certain range of frequencies. As the frequency increases in sound so will the number of LEDS lighting up in each column.

Audio input
AD converter
Microchip/Fourier Calculations
DisplayCircuit Board
The Audio device, microphone or AUX hookup, and the AD converter will both be connected to the microcontroller, Audrino Uno, of which all the Fourier calculations will be done. Then the microcontroller will be connected to a circuit board. The circuit board will be connected to all the Leds, the display.

The Musician
As a Musician I want to be able to see what kind of frequencies a song has in it. So that I know what frequencies can be put into and taken out of a song. With this I can remove un wanted frequencies in my songs and place new frequencies that will better satisfy my listeners.

The DJ
As a DJ I want to display my music So that I can draw the attention of my audience more to my music. With this I will draw in more people with by giving my audience a visual of my music.
