GRAPHIC EQUILIZER WITH MATLAB,SIMULINK
GRAPHIC EQUILIZER WITH MATLAB AND SIMULINK
This project is aimed at exploring the concept of building parametric equilizer using different band pass filters to different frequency bands and then assigning gains for each of them individually
Finally add all those loose ends from the gain block to a summation block to output through an audio device
function varargout = draft_gui(varargin)
% DRAFT_GUI MATLAB code for draft_gui.fig
% DRAFT_GUI, by itself, creates a new DRAFT_GUI or raises the existing
% singleton*.
%
% H = DRAFT_GUI returns the handle to a new DRAFT_GUI or the handle to
% the existing singleton*.
%
% DRAFT_GUI('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in DRAFT_GUI.M with the given input arguments.
%
% DRAFT_GUI('Property','Value',...) creates a new DRAFT_GUI or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before draft_gui_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to draft_gui_OpeningFcn via varargin.

% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".

Conclusion:
This sums up the project at full. the project isnt complete yet,it has to be made completely autonomus so as to play to the full lentgh of the song and play pause buttons should be provided in the GUI along with option to open simulink in the background without displaying
This project can further be ported to an executable file
