1. Digital Signal Processing Jill, Jon, Kilo, Roger Spring ‘06

2. Overview Project overview Team members and roles Project Approach Potential Problems Team Goals Schedule

3. Project Overview Digital Signal Processing (DSP) Synthesize audio signals with DSP chip in real- time to produce various sound effects -> make a guitar pedal TI-C6713 DSP chip Features of the kit: DA & AD converters, C6713 digital signal processor, anti-aliasing input filter, reconstruction output filter already on the board Comes with an audio headphone and microphone ports built on Plug the guitar in the mic port and the speaker into the headphone output port

4. Know Your Role Jill, Jon (Systems) – Signal Processing and simulation in MATLAB Kilo, Roger (Computer)- Programming in C on the TMS320C6713 board using CCS (Code Composer Studio) Team: DSP Add friend @ www.myspace.com/DSP496

5. Project Approach Figure out how to make distortion sound effect using Matlab; general research on various sound effects Translate Matlab code to C code for DSP chip Code Composer Studio Test I/O and master the DSP chip Use Matlab to create more sound effects Implement codes onto DSP chip Jill demonstrates the realized sound effects

6. Project Approach Jill, John, Kilo, Roger Kilo, Roger Jill, John Simulations C code Simulations Rather than all of us working on the simulations in Matlab and waiting for a final design before implementation. We are trying to work in parallel to face potential problems in the second stage earlier and we have a finished product faster. 1 st Stage 2 nd Stage

7. Potential Problems Other devices may be needed Matlab’s audio features Translation of Matlab code to C code Mathematical/programming efficiency for real-time processing

8. Team Goals Learn Matlab Design sound effects Learn digital signal processing in general Learn how to use DSP processor Complete the project in Spring ‘06

9. Schedule Final Presentation5/4 Implement and test additional sound effects4/20 Complete 3 nd sound effect; concentrate on final paper & presentation 3/19 Design Review Presentation3/11 Complete 2 nd sound effect and prepare for Design Review presentation 3/5 Implement distortion effect on DSP chip and test I/O2/26 Proposal presentation2/11
