    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

    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...
