		<title>Isolated Word Recognition</title>
		<description><![CDATA[This is the third and final project of EEN540 – Digital Speech and Audio Processing.
For this project, I will be using a corpora of pre-recorded subjects to test two different methods of isolated word recognition. The methods will both involve dynamic time warping (DTW), and this will be a speaker-dependent system. The corpora can be [...]]]></description>

		<title>40 Mile Range XTend 900 MHz RPSMA Configuration</title>
		<description><![CDATA[Our research group just bought a couple of these 40 mile range RF transmitters for our Everglades project. Doug Mann and I were tasked with getting them to talk to each other, and to our dismay, no tutorials existed on the interwebs. The documentation was little help because it kept on referring to the development [...]]]></description>

		<title>Compiling HTK for Mac OS X Snow Leopard</title>
		<description><![CDATA[The Hidden Markov Model Toolkit (HTK) is widely used in speech recognition research. Since I&#8217;ll be doing some multimodal speech recognition soon, I downloaded the HTK and tried to compile it for Snow Leopard. This didn&#8217;t work right away, and after scraping the bowels of the internet for help, I&#8217;ve finally managed to get it [...]]]></description>

		<title>EEN502 Project 3</title>
		<description><![CDATA[Problem 1 consists of four parts. 
I first recorded myself saying my first and last name. Then, the time waveform, wideband spectrogram, and narrowband spectrogram are generated and displayed. Finally, two 30ms vowel segments are chosen and their magnitude and phase spectra are displayed.
The code for all four parts can be found here:Code for Problem [...]]]></description>

In Part 1, the source sound moves towards a listener on the same plane. Part 1 code and figuresPart 1 sound
In Part 2, the observer is separated from the source sound trajectory by an offset.Part 2 code and figuresPart 2 sound

		<description><![CDATA[Guten Tag!
I&#8217;m posting this from my hotel in Germany. It&#8217;s my last night here after attending the Haptic and Audio Interaction Design conference at the Dresden University of Technology. I was presenting my work on the control of audio effects using head position estimation. I&#8217;ll have the PDF of the poster and paper in the [...]]]></description>

		<title>Getting Matlab 2008b+ to work with Mac OS X Snow Leopard</title>
		<description><![CDATA[Being the nerd that I am, I pre-ordered Snow Leopard as soon as I could and also installed it on the same day it shipped. I did a complete reformat of my HD to get rid of all the junk I accumulated during the Leopard days. Much to my dismay, Matlab 2008b did not install [...]]]></description>
