Is it posible?? - Santiago Fiscal - Jun 28 16:09:00 2005



Im new to DSP, and for collage want do design an
electric guitar effects box. The effects box will have
diferent amplitude, time, frecuency and distortion
effects, and since this is my first project using TI's
TSM320C50, i was wondering if this is a good starter
project, or Im way over my head?. 

So, should I do it real time processing , or use
recording and then process signal?, is this DSP fine?
what are your thoughts... 
Thanks Alex

I think this is a reasonable project since has a real goal and is doable 
with the DSP suggested. I imagine that you also play guitar and therefore 
perhaps you are a bit more motivated to make this project successful than 
another one. The main challenges will be dealing with non linear functions 
with DSP processing since  you can generate harmonic aliasing with the 
sample rate is too low.

You might want to take a look at our DSP-8300 small module. It is based on 
an Analog Devices ADSP-2186M and an AC-97 audio codec. It is only the size 
of a credit card and has similiar performance to the TI processor 
mentioned. We have a complete dev kit for $250.
