interface to play short .wav files

MtnFlyer

I found the Parallax SoundPal, which looks like a nifty little chip, but I need to play some pre-recorded .wav files.· I'm looking for a chip that can store 3 or 4 files, each·being about 3-5 seconds long.· I need to be able to play the selected .wav file on a command·provided·by the·BASIC·Stamp.· Has anyone heard of such an animal?· Thanks. <Edit:· .mp3 or other audio·formats OK too!>

If you can't find what you're looking for as an available product, you can shamelessly go toy hacking to get what you want from another product that has the functionality you are looking for.

You could look for something like this on clearance somewhere:

http://www.amazon.com/Lil%27-Reminder-Personal-Digital-Recorder/dp/B000OZ046G/ref=pd_cp_e_1/182-4593125-9422700?pf_rd_m=ATVPDKIKX0DER&amp;pf_rd_s=center-41&amp;pf_rd_r=14GW557A8Y0EZ48HHVC2&amp;pf_rd_t=201&amp;pf_rd_p=413863501&amp;pf_rd_i=B000VEM98Q

Even at $4.99 a piece, they should be easy to hack into with minimal cash outlay. You can rig it so the BASIC Stamp activates the play button after you've used the device as sold to record your track. They only hold about 10-20 seconds of recorded voice and it isn't super quality. You'd have to use a board for each recording as you can't address separate messages... new recordings overwrite the previous ones. And you'll have to step down the voltage as they are 3 Volt.

The attached file is one of these devices opened up. I received a two pack for Christmas stocking stuffer; found it useless as a memo device and decided to hack it for experiments.

The Vinculum VMusic2 plays MP3 files and has an SPI interface but is·a bit pricey -http://www.vinculum.com/prd_vmusic1.html·; the Nuvoton Chipcorder ISD 1700 series -http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=ISD17120PY-ND·has an SPI interface and pushbutton mode and·is available for ~$10 from Digikey depending on the length of the message that you record. The Chipcorder is very easy to use if you place it in pushbutton mode.

Thanks very much for the advice.· You're leading me down paths I didn't expect, but that make a lot of sense. --Jim
