    Hello everyone,

    I would very much appreciate anyones help!
    I have the following problem:

    When activating the recording in Logic, there slowly grows a noise that is not there in the beginning but get's worse and worse after approx. 20 sec. until finally everything that comes through the microphone is distorted.

    I use a USB audiointerface and a little pre-amp. the microphone is a phantom powered one but the same happens with standard microphones.
    It used to work fine with other microphones when I tried it a couple of months ago.

    Plugging of the power cable from my macbook doesn't change anything.
    I have to restart logic to get rid of the noise but of cours it starts again after 20 sec....

    Any ideas anyone?

    Feedback, turn down your monitors or use headphones.

    What interface is it?

    What is the noise like - screechy, buzzing, rumble... pick an adjective.

    I doubt it's feedback.

    Reads like a monitoring issue, a select box or button in the software OR the soundcard interface to allow for, ah, monitoring.

    Try setting your buffer larger under audio in the preferences tab.

    Maybe that will help?
