Mister_e,
I have been looking at the chipcorder you mentioned as well as their 2500 series more closely and I downloaded their sound quality examples and I think they would be acceptable. I read a bunch of datasheets on the 2500 series and its use with a MCU and that one sounds rather confusing.
Elsewhere on the net someone had a simple 2500 circuit that was storing 10 sounds each accessed by a switch.
So, if it is just simple sound play back based on a specific address being fed in with a mechanical DIP switch couldn't a high/low or pulse out commands on a PIC accomplish the same thing without the pages and pages of reading for MCU use? I think that may be important for more dynamic use of the sound, but all I really need is for a momentary contact switch to play a specific sound and stop at the end of it. Wait for another switch and do it again. Nothing fancy.
I think I can wrap my head around the project if it doesn't need to be complicated with data all over the place. I don't even think I need those 5 address inputs available as it looks like 3 would give me more than enough addresses (I'm figuring on 5 sounds in total with the pic setting the pins based on how the three users buttons are being pushed).
So when you mentiond the 1100 were you thinking the pic would act like a simple switch instead of a physical switch or were you thinking I really had to dig deep to get this out with MCU control? On a side note the data sheet for the 1100 series doesn't list MCU as an option.
Next, because this is going into a very small space and it will be run with a single 32mm 6v camera battery I have to drive a speaker that is equally small. What do you think would be better? A laptop speaker such as this one:

(the 16x35 mm would probably be the largest I could fit) or this one:
http://dkc3.digikey.com/PDF/C051/1270.pdf
(the 20mm micro speaker, but I don't know how the 7 ohms works in a 8 or 16 ohm system) or this one (on the same page):
http://dkc3.digikey.com/PDF/C051/1270.pdf
Which is a 30x30 card type speaker, which makes it perhaps too big, but no thickness which is also critical.
I would need to get the most volume possible with no amp as there will be zero room for that.
Next guestion is in regards to space.
I see that some of these chopcorders come in die form. Now I know that this isn't something that can be done at home with a regular soldering iron, but that whole concept appeals to me because the space used is next to nothing. Just out of curiosity, is there any place that can set up this sort of thing and tie it into my circuit pattern? I imagine the cost would be too high, I'm just mainly curious how it works.
Hope you are still awake after this list of questions. I hope to order the PIC, sound chip and a couple things for making a "recording studio" with my next Digi-key in the next few days so if you or anyone else can get me over this humb I'll be good to go with my order.
Thanks.
Bart
P.S. edit. the 16F628 PIC may not have enough I/O ports. With my 3 switches and 10 LEDs that only leaves 3 to set the address for the appropriate sound and to trigger that sound. Perhaps 18 I/O would do it. Size still an issue unfortunately.
