    First off, I know NOTHING about audio circuits, I have a long history with digital control electronics.

    Now I have an application where a digital control board that I have built needs to "speak" to the operator and alert them of certain conditions. I purchased this;

    Here is the datasheet:

    The module has a built in mic and it works as expected, my micro controls it as expected as well.

    Now, the question, I want to be able to record sound to the module directly from my computers audio out jack (headphone jack). Can I do this? If so what pins to I connect to? I plan to manually hold the record button on the module while the audio is being recorded so all I need is the ability to stream sound to the chip.

    Thanks for any help!

    The chip has an input for an electronic signal for recording and the module has a microphone input. The datasheet for the chip shows both.

    If you feed your computer's audio to the microphone input then it must be attenuated.
