**NOTE: When doing DFT make sure to right-click [COPY] to save your selected samples.
Then click [DFT] to apply fourier transform!**
1. properly play saved wave file.
i. click on [start] under [Record] to start recording.
ii. then, click [file] on the top-left corner and click [save as]. Choose a destination to save the file.
iii. open the wave file you just saved, and it should play normally.
2. apply windowing technique on a selected portion of the wave.
i. click on [file], hover on [open], then click [.wav] to open a wave file.
ii. select a portion of the wave using left-click and drag.
iii. click on [windowing] beside [file], then choose a windowing techinique and it will automatically apply the technique you chose.
3. DFT and inverseDFT
i. select a portion of your wave, then click [DFT] to draw the frequency graph
ii. After you draw your frequency graph, you can click [Inverse DFT] to
re-draw your wave from the selected portion
4. Filtering
i. Select a portion from your frequency chart, then right-click and [Filter]
ii. This will automatically iDFT the filtered frequencies and re-draw the wave
5. Zooming and Scrolling
i. Use mouse-wheel on the wave chart to zoom in or zoom out.
ii. This will create a scroll-bar on the bottom of the chart to navigate.
