Statistical and Analytical Approach to System Alignment

The current project describes the design of a tuning or alignment processor for a system based on multiple satellite speakers and a single subwoofer. It explains the methodology used to solve this problem and the procedure to arrive to a viable solution. On one side, the procedure was based on filter design techniques to optimize phase relationships; however, these phase relations are often unknown due to the possibility of changing the relative positions of the speakers. Accordingly, a statistical analysis was used to determine the most stable set of parameters across different speaker locations and acoustical environments, implying that the same alignment parameters can be implemented in multiple circumstances without significant performance degradation.


SpeakerDrum is an instrument composed of multiple Dual Voice Coil speakers (DVC) where two coils are used to drive the same membrane. However, in this case, one of them is used as a microphone which is then used by the performer as an input interface of percussive gestures. Of course, this leads to poten- tial feedback, but with enough control, a compelling exploration of resonance haptic feedback and sound embodiment is possible.

Alternative Methods of Compound Spatialization

This project intends to do an analysis of differ- ent spatialization algorithms in order to develop multiple alternative methods to simulate apparent positions of sound phenomena. Nevertheless, beyond the research development, this project represents an effort to clearly merge different types of knowledge such as mathemat- ics, physics, signal and system analysis, programming languages, etc... pointing towards an artistic objective. At last the reader will encounter a detailed description behind the development of a suite of algorithms presented as plugins for a single purpose: to pursue a burst of possi- bilities in mixing engineering regarding the manipulation of stereo imaging.
