Let's see.....
Hi all,
I'd like to begin by a special thanks to all the professionals who are taking part in this thread in particular.
For starters, it is true that the output of the microphone needs to be DC shifted, amplified, and applied to an A/D converter -wether its an independant circuit or a module inside an mcu, it does not matter, so thanks to "Sceadwian" for his advice. Salutations man!
Now the other big issue. Well as I probably mensioned (if not in this thread then it's in another one) that I'm still a student and I'm learning more and more with every contribution you gentlemen make, so thanks. Now the sampling theory states that applying Nyquist criterion is the solution, but how to determine the frequency of random sound?(there's no silly question but there's a silly answer, right ?), if I'm gonna double it to obtain the sampling frequency?
- About the "dynamic resampler", what do you precisely mean? Is it just obtaining different sampling frequencies? and how?
- I've never used a DSP PIC but I guess this is the right time. What's the best PIC of this kind? 'cause I want to proceed as soon as possible.
And lastly, I'm gonna convert the sound samples to an 8-bit representation, and I'm not really aiming for a very high quality - stereo- surround sound type of thing (lol) so obtaining sound that is just audible is what I'm really going for.
Hope to get more of your valuable help gentlemen!
thx a lot in advance.
