Digital Signal Processing

Redegg

Hi, I am starting to make a guitar tuner. Taking input directly from a guitar to a sound card. I will be using DSP for it. to be honest I dont even know ehre to begin. Books just seem to have loads of random formulae. It's quite scary to read too. Has anyone ever made one before or has anyone worked with DSP?

amen

break it down in small bits then is never that scary
first of all do you have soundcard working and picking up the signal
after that is just a matter of sampling the sound and applying a forumal to work out the note

I know someone who made one using 8051 assembly code. It was quite easy really.

DSP aint so bad, have you got MATLAB? I assume it will be C that you are using.

From what I can remember it is not too bad of a project but you need to scratch up on whatever software your using. If you are good at programming you will find it very easy.

Not using matlab. Doing project with C#?

So you have 3 steps:

(1) Learn how to design this using pseudo code, in other words get an understanding of how this is done www.google.ie .

(2) Learn C#

(3) Integrate the two.

Your first step is to google for answers and read loads of stuff off the web.
