After the run of the "MyEqualizer.m" file a graphical user interface appear. By pressing the "Load" we can load audio signal (type .wmv). After we can model the frequency behavior of the FIR filter that is used to filter that signal. After we can listen the filtred audio signal by pressing the "Play " button. In the GUI M-file I m using three importanat function: [ ]=coeff() that generate cell contain the coefficient of the equalizer, equalizer_plot() who plot the frequency behavior of equalizer and the equalizer_play who filter and play the filtered audio signal.

This is a C code which has 3 user defined functions. AudioRead(), Filter() and AudioWrite(). The AudioRead() function read the .wav file and retrieve their samples. The filter() function does convolutions on input audio samples with matlab’s filter coefficients. The AudioWrite() then take these output samples as input and write them in a wav file. For this Project the DSP kit used is DSK6713.
