Here is an update to my project. I brought the roman black board and it does work. I tried many band pass filters and the quality is terrible. The only way to even get decent quality was to have a speaker in an enclosure. That did more to filter out the noise, but it still wasn't great. I settled on a windbond device. I wouldn't waste time or money with this method.

Hi, the BTc system was never designed for *high quality* sound! It's strangths are in other ways, mainly that the PIC microcontroller can also be used to do other tasks, all in one self contained module, and that is quite memory efficient.

Which speaker were you using that sounded terrible? For better sound quality I suggest a speaker with a larger diameter, ie 4" or 6". The tiny speakers that are supplied (free of charge!) with the product are not meant for good sound (they are "scratchy") and are only for small self contained applications like little robots, talking remote controls etc.

The BTc module sold is optimised for general purpose control applications and has source code, so you can use that one module to operate servos and play speech clips, or control a small device with some talking feedback. Or be used as a complete talking remote control all with the one PIC in the one module with its own 5v regulator and tiny low-sound quality amp already built in.

If all you want is something to play a sound, or specifically need high quality sound then there are plenty of options including the Winbond chips and $10 MP3 players from the supermarket.
