    Hello, I'm having trouble tracking down a cable converter (or circuit, if necessary) and hoping someone might be able to point me in the right direction.

    Basically, I just need something that takes a male mono 1/4" audio cable, flips the polarity, and then outputs the flipped signal via another male 1/4" audio connection.

    Thanks for reading.

    EDIT: The application is to convert a signal like this:

    ~5 V----- ______
    ---------|------|
    ---------|------|
    0 V _____|------|_____

    to this:

    0 V ____--------_____
    --------|------|
    --------|------|
    -5 V----|______|

    Do you mean an active circuit that amplifies the input by negative one and presents that to the output?

    I mean, the way you phrased the question, the first thing that comes to mind is, "Just reverse the wires and the ground on the receiving end will make the signal LOOK inverted".

    Please try again with different words and a high consciousness of the fact that I can't read minds...not even a little bit. Just ask my ex-wife!

    If passive signal just get some connectors and wire in reverse.
    If active I'm not too sure but I'd say a simple chip.
    If you want it switchable ie. foot switch phase change maybe a h bridge would work.

    What type of signal is this? What are the two items being interconnected?
    It makes a difference in the options available.

    EDIT: #12 - Yeah, but imagine, for a moment, if we COULD read minds ....

    Hey, thanks for the replies. The signal is audio and it's being sent from a pulse generator (positive pulses) to headphones. I had originally thought it would just involve reversing the two signals, but I wanted to see a) if I was missing something, and b) if there's some standard converter that could do this.

    Two signals? You mean stereo?
    You can always reverse the wires on the speakers. Mono or stereo, it will work the same.

    Sorry: "two signals" as in the sleeve and tip of the audio cable.

    What do you expect to be dfferent if you inverted the signals to headphones?

    There are potential differences in the effects of sound by rarefaction waves vs. compression waves.

    Does anyone know if there is a converter that will invert an audio signal? Thanks for reading.

    Just reverse the wires, as has already been stated.

    I'd expect a lot more dead husbands.

    Yup, reversing the wires would do it—but I'm looking for a cable converter that does this. Does this exist?

    I would not think so, easy to make it though.
