Arduino Synthesizer

A reprogrammable granular synth based on an Arduino Uno

An experiment in sensor input and audio output using microcontrollers. With an Arduino heart and any amount of inputs, the sonic realm was never the same after the birth of the Far Out Frazzleator!

Acoustic Transducer Theory Final Project

Designing and building a solid bookshelf speaker

This project required the application of many acoustic principles to achieve a pleasurable sounding speaker enclosure. The ported tube design is the tried and true method of the consumer market and this build delivered; winning three out of four awards available. It also allowed me to use my woodworking skills to create an air-tight build using 45-degree miter saw cuts.

Automated Impedance Tube

One of my senior design projects at the University of Miami. It was published and presented at the Audio Engineering Society's 138th conference in Warsaw, Poland.

One of the fundamental tools of acoustics is an impedance tube. It measures the way a substance interacts with different frequencies. Current tubes are expensive, cumbersum, and hard to use so we developed an easy to use, lightweight solution for under $150. Shout out to my buds, Connor McCullough and Diego Ugaz, for the great work! Thank you to the AES for publishing our report and the opportunity to present in Warsaw.

Phoneme Analysis and Recognition in MATLAB

Digital Speech and Acoustics Processing

This project combined many concepts learned in Digital Speech and Audio Processing and made each student realize a personal inventory of phonemes. Phonemes are the building blocks of words. They are the smallest units that can change the meaning of a word.Kiss and kill differ by only one phoneme but their meanings vary greatly. In addition to the acoustics of the human vocal tract, the main concepts reinforced in this project were sampling, windowing, spectrographic filtering, generating linear prediction spectral envelopes, and three-dimensional plotting. The MATLAB code was run for each word to generate and save the given plots. For higher resolution, the recordings weresampled at 44.1kHz with 24-bits per samplebut to highlight the frequencies of the human vocal tract, the y-axes of the narrowband and wideband spectrographs were truncated to 8kHz.

Sometimes I get to capture the magic of the moment with a robotic eye :)

3D Printer Assembly and Calibration

A test of my mechanical engineering and patience assembling and calibrating the Prusa i3 printer.

Assembling the Prusa i3 taught me many lessons and skills not taught in the traditional engineering curriculum. Applying theory is much more testing than bookwork and is the reason I love real engineering!
