Audio and speech processing

For this work I need to use the programs in Java, processing or Octave/Matlab to prepare a narrative on digital waveforms, spectral analysis using the FFT and the Spectrogram to demonstrate your knowledge of how they work. Make sure that each plot can clearly illustrate the shape of the waveform, i.e. if you have to zoom in to get this, do so. A thick coloured block is not acceptable. The results from your plotting should be placed into a powerpoint presentation and along with the plot a sound file should be inserted into the page (it should be imported as mp3 to save space). The documents should also show on the following slide to each plot the programming scripts to generate the wave and its graph. The graphs should have titles, labelled axes and have a caption in the document
