During this weekly meeting, my project significantly changed. After email contact with the engineer Ryan McGee, the approaches of my project have changed. Ryan McGee is the head engineer for a sound engine that converted seismograph data into audio signals called sounds of seismic. A link to his website is shown below:
In his email, Ryan discussed that there are two different techniques for representing data with audio. The first is Sonification. Sonification is the mapping of data using a sound producing source like a MIDI file input to an audio synthesizer. This technique is the exact same technique I was already implementing. He also discussed the technique of audification which is adding gains the the raw data signal so that it can be adjusted to an audible signal. For his Sounds of Seismic engine he generated all of the audio in MATLAB using the soundsc function. This function converts the magnitudes of an audio signal between -1 and 1 for controlled volume output. Professor Dosiek examined my working Pitch/Velocity generator code and suggested that I make a block diagram representing the Audification approach for next week.
