Hi
im sorry if this a wrong place to post such qusntions, please point me
to the right groupt !!
otherwise, my question is
our company planning to work on electionic dictionary(with other
electronic products company ) which includes about 30 hours voice, i
want to ask what kind of microcontrollor/memory chip can hold such big
amount of sound? some ppl told me that 8mega is enough but i wonder if
there's a special sound format that can put 30H sound in 8mega memory
chip...

thank you all.

I don't know myself what chip to use, but you'd better swap the mega8 for
something that can encode/decode an mp3-like format. I don't think you
should be looking at Atmel micros for that, I think they only have decoding
c51 microcontrollers.

And oh, something like 512MB of flash would be useful.

Hi, you'r right, we first took mp3 flash memories for that, but it's
was too expensive , also i saw a product that hold more than 25h
sound, but not was mp3 flash mem, was regular chip as the creator told
me, i also hear about a sound format used with microcontrollers called
SUD, but i didn't find anything about it with google...
what about Z80 with more memories??

thank you...
