    Just for simulation purposes in MultiSim 10 what would be the ideal parameters for for a ac input to sim an audio signal, more specifically a song. I want to run the input through a few filters constructed with op amps.

    Thanks

    I'd think you might need multiple sources, each having a different frequency. Example: source 1, 100Hz, source 2, 1kHz, source 3 5kHz. The voltage levels depend on what you're trying to model.
    Someone else may have a better idea, but that's how I'd go about it....

    If you use LTspice, you can use a .WAV file as in input, and then listen to the output of your simulation.
    Below is from the LTspice help file:

    Be aware that the simulation time can be ridiculous if your .WAV file is long, or your circuit is complex.

    Exactly...keep the sound sample like 3 seconds long, or you'll be there a LONG WHILE!!!
