File Information

This is a GUI for Filtering. The user has an option to choose either
his/her voice signal for 5 complete seconds or a loaded signal on
 his/her system. The loaded signal needs to be a .wav format. I have
 employed Additive White Gaussian Noise (AWGN) and the filtering for the
same is provided using a Butterworth and Chebychev filtering. A sample
 .wav file has been provided to the user.If you have any questions or
comments please get back to me. I will return at the earliest.

Short Note on running the file
1) Click on "load a sound file"(Radio Button) and hit load the sound
file(push button).
2) Click on "play original" to listen to the loaded file.
 3) Click on "Add noise" to add a AWGN noise.
 4) Filter the noisy signal using either Butterworth/Chebychev Filter.
 5) See the waveform of the signal using the Plot signal.
Alternately you can follow the same procedure with your voice signal by
clicking on "Speak into Mike".
