Using a PIC to record voice

[mister_e]

You could still use any MP3 Codec ICs and store those MP3 on a flash card.

Sure the roman Black stuff have it's own advantages. I already looked at Luciano's link. Seems nice to me.

Anyways, minimum requirement for better results, fast ADC and fast Memory. Since it's voice, i figure any regular PIC16Xxxx and most SPI memory would do the job. But yeah... you may need to use the MSSP module instead of SHIFTOUT.

There's still the Parrallel memory type... too much a waste of I/O to me.

ISDs chip are not as this bad, but i think they're a bit too much overpriced for mass production. I think they have released a 44.1KHz chip now. At least they talked about that a while back.

As there's so much new stuff each and every day... it's hard to follow everything. ISD are popular and easy to play with... sure there's something else.

If i find time before i die, i want to test few ideas i have in my small head since awhile...

I'm trying to minimize silicon and real estate to the maximum extent possible

Fair enough!

I feel I have to warn you about the PIC route to achieve this though as I spent many weeks trying to achieve this and failed (sob - not something I admit to lightly!). I wish you the best of luck with this.
