This directory consists of code and data required to perform 
signal to noise ratio computation.

data/	-     consists of data 
		       plot_data/ -  data obtained as output used to plot
				     different graphs in the experiment
		       plots/	  -  consist of gif files of the plot
		       speech_file/- consists of audio files used in 
				     experiment - these are in raw format

report/	-     consists of report for this homework

src/	-     consists of matlab code for SNR computation
	matlab_code/   - 
	snr_calculate.m - consists of matlab code for obtaining SNR of a
			  speech file using different values of frame
			  duration and window duration keeping noise
			  and signal threshold values constant.
	snr_calculate_thresh.m - consists of matlab code for obtaining SNR
				 of a speech file for different values of 
				 noise and signal threshold keeping the
				 frame and window duration values constant.
	plot_*.m	- consists of respective code for plotting 
			  purpose - this requires input data which
			  is in data directory.
