    If a cable has only one ferrite, does it matter which end it's on?
    Specifically, I'm referring to a FireWire cable connecting a computer and audio interface.
    Theoretically, it would apply to any cable.

    without any scientific reason, I would put it to the side that seems to be the closest to any source of interferences. (computer monitor, ac adpters...)

    The ferrite ring is not there for the cable, it's there to correct an EMC problem in whatever device the cable was originally supplied with. When using it with that original device, the ferrited end should be plugged into the FireWire socket on the device. If you are using the cable on a different device, then, in principle, it does not matter which end you plug into where, but I would go with the original idea of connecting the ferrited end to the device and the non-ferrited end to the computer.

    Thanks for the information.
    This is a cable from another device.
    The current device came with a FireWire cable (no ferrites), but it's an 800-400 cable and I have a 400 controller.
    I just grabbed a 400-400 cable that I had, laying around.
    Since the device's supplied cable doesn't have a ferrite, I'm assuming that it doesn't matter.

    Much like pcrecord, I always thought it was to help with outside interference.
