Create a program that reads a $.$wav files, and then plot the waveform of each channel on the screen.Your program should first show an open file dialog box for loading the wave file. Your program should then display the waveforms on the screen $($see a sample below for stereo sound$).$ Also show the total number of the samples and sampling frequency on the screen.image.pngYou can Google the $.$wav format. We assume that the audio file is PCM coded and stereo only $($i$.$e$.,$ no mono or multi$-$channel beyond $2),$ and the total number of samples will be an even number less than $65536.$ Some $.$wav file examples will be supplied later, and the files for our test will be similar to them.You can call any existing library function that automatically interpret the $.$wav file or write the function by yourself. For displaying waveforms, you have to draw them using basic pixel$/$line plotting operations$),$ i$.$e$.,$ you cant call an existing library function that directly outputs waveforms.You should submit your source code, together with a report that includes screen shots of open file dialogs and displayed waves of the sample inputs, as well as the key GUI functions you have used.
