    Where can i get Analog sound chips like the TIA,POKEY,SIM's?

    Which analog sound chips brands and names is there and how can i trigger the sounds with a microcontroller please?

    You're asking extremely vague questions. What DSP? As for sound, Winbond has a line of chips called ISDxxxx that are microcontroller compatible. We use the ISD2560 in a couple products, the latest being the AP-8 audio player.

    ·Which brands,models,names for DSP sound chips and analog sound chips are there please?

    ·How do i use them with a STAMP?

    ·Do u guys have tuturials on DSP sound chips programming them and interfacing them with the STAMP?

    As I pointed out we use the ISD2560 and if you're interested in learning about it you should consult the data sheet. It can be used as a stand-alone device, or interfaced with a microcontroller (as we do on the AP-8). I wrote a couple articles about it for my Nuts & Volts column, you can find those in the Downloads section of our web site.

    No, we do not have any DSP tutorials.

    Thanks

    Can u make up a DSP tutorials?
    Is there ISD2560 tutorials?
    Is there AP-8 tutorials?

    Can u make them the next time u write some new articles please?

    Markphaser,

    ·· Since we don't carry any DSP chips we won't be publishing any tutorials on them.· You can find a lot of information on the internet (Try Google).· As for the others, there is plenty of documentation and examples.· Is there a specific item in the documentation you don't understand?

    As I pointed out earlier you can find a couple articles on the ISD2560 in our Nuts & Volts downloads section. The AP-8 comes with complete documentation and a demo program to show you how it works. As Chris pointed out, we don't carry DSPs so I won't be writing any articles or tutorials on them -- but you're free to post what you learn here for others to benefit from.

    Thanks guys

    Do u guys have anything on how to build a hardware component network to control a audio sound chips or DSP sound chips

    Like variable pots to control the waveforms,attack,decay,waveshape,ring modulators,filters with external hardware components to control the analog sound chip or a digital DSP sound chip?

    Here is the Datasheets for the atari POKEY sound chip:
