First basic information anyone should learn is "Googling", so:
Check this out:
and among the first few links:
started the project in Jan 2010???).
and yes, many other links are electronics-based. If u want to do it
digitally in Beagleboard (computation-based) and responds in realtime,
some proper performance assessment is needed.
Other "basic information" as u requested which u will need are:
a. stereo audio in and out - for the beagleboard. find out how to
read/write to that port.
b. Beagleboard has a DSP - how to use that:
BB is used for SDR (software-defined radio):
so I would not rule out the performance capability of the BB for
"The DSP is open - Beagle Board"
c. Find out all the opensource tools and libraries available (eg,
d. And lots of theory: voice encoding/decoding, encryption/
decryption, different types of transformation for digital signals etc.
Finally, here is one but using another TI's DSK:

Good answer Peter but i think self searching is the best way to know one's own requirements. I've asked the dumbest of the dumbest question in forums like Stackexchange where i got ridiculed pretty bad, it's because i've never tried thinking in my own shoes and learn stuff. So i encourage you to answer in a more stern manner because technology is never easy to understand in other's thinking or action. I hope you got what i really meant.
