how to download audio from pc to windbond/ISD chipcorder chips?

I was looking at nuts and volts #65 and 66. I am interested in using the ISD series of chips, probably to isd2560.· I see the schematic to record directly to the chip with a mic, but I would like to know how to download files directly from the computer to the chip.

I would like to use th basic stamp to randomly playback each file when a motion sensor is activated.

Thanks

    You can't download files directly from the computer to the chip. They're not stored digitally in the chip. They're stored in analog form. The computer has to be able to play the file and you can record it from the computer's audio output. There are some "programmers" for this chip that attach to a PC. They basically automate this process, but you still have to record the audio from the PC's sound card.

    Take a look at the Nuts and Volts column #75 for programming a QV306 with a Stamp2: www.parallax.com/Portals/0/Downloads/docs/cols/nv/vol2/col/nv75.pdf.

    The bare ISD2560 is a little different, but most of this setup should work. Compare the
    WinBond datasheets for the ISD2560 to the ISD4003 used in the QV306.

    is the qv306 the best way to get wav files played with a stamp? Are there other ways people are doing this these days?

    I hooked an iPod up to a megaphone. That was fun but it looks like the qv306 could be cheaper...other ideas?

    The Music2 from Vinculum works well as an MP3 file player. The successor to the QV306 (the QV606) plays MP3 files directly. A number of other companies as well make MP3 players that are controllable from a microcontroller like the Stamps.

    thanks mike!

    Jon Williams said "There’s More Coming ... Like I said last month, sound projects – especially those using ISD chips – have generated more e-mail than anything I’ve ever written about. That hasn’t gone unnoticed by Parallax. The sheer coolness of the QV306M4, the ease of use with the BASIC Stamp and with so many customer requests coming, Parallax and Quadravox have joined forces to develop new products. Stay tuned, there’s some really cool stuff on the way."

    When I do a search on sound on the parallax site, I see only three products and none from Quadravox, that I can tell...maybe the new products Jon spoke of above came and went...

    I'll check out the QV606 and Vinculum stuff...thanks for the leads!

    Parallax used to carry the QV306, then Quadravox started to have delivery problems because they couldn't get the chips from ISD, probably around the time they became part of WinBond. Quadravox started development of the QV606 based on MP3, but began to get ISD chips again and still makes the QV306. Parallax hasn't carried them though.

    http://www.vinculum.com/prd_vmusic1.html = £20.80 (needs external usb flash drive (can get 1GB sony drive from ebay for $8))

    http://www.quadravox.com/QV606/QV606.htm = $57 (16Mbit) - $72 (64Mbit)

    In the Completed Projects forum, there's a project I built with a Propeller and two VMusic2 that plays tracks in a specific order and directs the audio through relays to specific speakers, all specified by a file on the USB flash drive.
