    I am looking to develop a sound project module which will provide the following criteria.
    1) The sound project file will play a single WAV file of up to 20 seconds in length, then stop and reset.
    2) Capability to download a WAV file from a PC to the sound project module via USB (optional interfaces will be considered).
    3) WAV file would be 8 or 16 bits sampling rate, mono, 11,025Hz (optional rates will be considered)
    4) Activate the device with a momentary push button via control leads emanating from the sound project module.
    5) Adjust the volume to the speaker via a small internal potentiometer (optional)
    6) Provide .5W, 1W or 2 Watts audio output into an external 8 ohm speaker via leads from the sound module.
    7) Operate from a 3V, 5V or 12VDC power supply.

    Can someone please provide a model of a sound module which will accomplished the above.

    You won't get much help with a request like that. Everyone here is a volunteer; you're asking for a significant amount of work. And you haven't demonstrated that you've made any attempt to do anything yourself.

    You could start by googling all your keywords and seeing whether someone has already designed some of the components you need. Also try to find hobbyist sites that deal with these subjects, such as sites for microcontrollers, audio amplifiers, etc.

    Unless you actually WANT someone to do all of your design for you. In that case, try a site like
