Audiophile help needed for project. (wiimote speaker)

[Howard_Casto]

Been messing around with the known data on the wiimote, and I've been able to get the wiimote speaker to actually play an audio file!

The problem is the audio quality is terrible... yes I know that the wiimote speaker isn't great to begin with, but this is due me running the wrong data format. 

I need a converter that will convert a wav file to 4-bit unsigned ADPCM at 3000Hz.

Before you start suggesting a bunch of programs, the 3000Hz part is important.  Thus far the lowest rate I've been able to select on a program is 6000Hz, which is roughly twice what the puny wiimote chip can take. 

Can anybody help me out on this?

sounds interesting...

  Just a note however...  that the Wiimote may be getting low quality audio on purpose... probably due to the amount of bandwidth the stuff could take up.  Which also may drain batteries 100x faster as well.

thanks for the link hk.... that program seems to do all the conversions I need. 

Still having trouble though.  I can get the stuff to play just fine, it just sounds terrible.  I'm wondering if some sort of delay needs to be added when pumping the data to the wiimote.  Right now I'm just throwing the maximum 20 bytes at a time at the wiimote as fast as I can

oh well... at least it's progress... thus far only one other person has actually been able to send audio through the wiimote and their app isn't very compatable with windows pcs
