I have been studying DSP for quiet a while now with little success. I=20
need to do a little lab work if I am ever going to grasp the basics. In=20
my search for usable hardware I recently found a setup that allows=20
signal access to the interface between an AD and the DAC. It is intended=20
to be used with the Arduino Uno but should be adaptable to any=20
interface. It is available from ladyada.net as a kit for about $22.  I=20
have seen it called "audio Shield" and "wave Shield".  I have mine built=20
but not yet tested due to personal ADHD & other distractions. It would=20
be best for one to get the specs & info from LadyAda.

All of the other micro-DSP packages seem to make it difficult or=20
impossible to access/modify the digital data stream.
There are many high quality math lectures available on Youtube.com if=20
you can only pick out the ones you need!

I wear hearing aids which are expensive and not really as good as they=20
could be. I ordered Logitec earbuds for my laptop so I could watch the=20
Videos without disturbing others. I am amazed at how much better I hear=20
that way.  Quality Earbuds beat $4000.00 hearing aids.  It would be nice=20
to have a multichannel equalizer included but for now I am planning a=20
simple stereo amp in my shirt pocket. Mic's probably on glass frames. =20
People don't really notice earbuds thanks to all the youth running=20
around using the...
BTW, hearing aids don't even try above 8 khz.

That which can be destroyed by the truth should be.
