The following zip file contains two routines for analysis/synthesis of HNM. HNM is a analysis/synthesis model of speech,like classical LPC model. Due to the limitation of my ability,i only implement a simply version of HNM,so welcome for somebody to improve on it.

If you pass in 2 vectors it returns the unnormalized distance between the vectors, the accumulated distance between them, the length of the warping path (the normalizing factor), the warping path points and both warped input vectors. You can plot the results too if select the pflag=1.

In addition to the program file there is a text file CodeGroups.txt that has some code groups that can be sent. The three documents MorseCodePlayer.pdf, .htm, .docx are just three different versions of the help file. The code speed(rate of dots and dashes), word speed(period between words) and audio frequency of transmitted dots and dashes can be adjusted.

A fourier filter for time-series signals. Version 1.5, May 4, 2007, is calibrated specifically for time-based signals. Does not require the Signal Processing Toolbox. By adjusting the parameters, you can create lowpass, highpass, bandpass, and bandreject (notch) filters with variable cut-off rate.

The Matlab code investigates the harmful effects of high power amplifier on ofdm signals. It is imagined that the amplifier destroy the amplitude of the transmitted signal due to saturation and has no effect on the signal phase. The model is acceptable for solid state amplifier to some extend.

This simulator creates a source to microphone impulse response in complex room environments. It's based on the image method by Steven Boll'79. You may select frequency dependent wall coefficients and orientation dependent sources. Please refer to the tutorial.

This application can be useful to understand how to use microphone (and timer) and how to record. Just execute the file, then click "test" and say a word (wait 1 second) say another word, etc. you can save and load the database. I used this software for voice recognition but I only left the recorder part in this file.

alculate the normalized partial energy sequence (NPES) for a given signal vector X. If a particular transform is capable of capturing the key features of a signal in few coefficients, the NPES will approach unity for relatively quickly.

This file contains MATLAB functions, m-files, that do Huffman coding and arithmetic coding of integer (symbol) sequences. Complete coding may be done by calling an easy to use main program (or main function), where input argument is the sequences you want to compress and the output is the compressed bitstream, as a vector of bytes.

In many filtering problems one receive not just a single measurement, but a set of measurements at each time step. The most straightforward way of dealing with such variable cardinality entities in Matlab is to store them in cell arrays, but for various reasons the user may not want that.

If applied to a matrix, the function FILTFILT (Signal Processing Toolbox) calls itself recursively for each column. Internally FILTER is called twice, but this can be performed with a matrix directly to avoid the unnecessary overhead. For a [100 x 100] matrix FILTFILT is about 10 times faster with the patch! The function PatchFILTFILT creates a copy of the original function and modifies the source such, that matrix arguments are processed directly.
