Hi all,
What i'm after here is something a bit like one of those naff Xmas/B'day cards with a scratchy (but hilarious) audio playback when opened. I would prefer slightly better quality but nothing audiophile! lets say 3 sec audio, single channel, 22khz, battery powered, finer points TBA
I've done something similar to this before, the hard way, with a PIC, an Eprom and an R2R DAC. I know there are (or were) fully standalone single chip solutions too but they are a bit expensive and my old R2R design would be well and truly sledgehammer/walnut territory for this.
Anyone here done anything like this?
Ideally a codec for a PIC would be perfect and i could use a sml PIC & a little E2PROM but i'm open to suggestions....
Cheers.
Carl
