    “Dick we’ve been streaming sermons to the PC for years and never had this issue, so i don’t tend to agree it’s a PC issue. I could be wrong, I was wrong once 😊”

    As of now you can up that to twice…
    If it’s the same computer you’ve been using “for years”, it’s time for it to go through some “house-cleaning” or be replaced. The fact that your Qu-drive recording and the house sound were good points SQUARELY at the computer…or bad karma.

    Not necessarily so Dick. It could be a loose USB or USB-B connection, which would easily cause crackling noises. I never checked this atthe time ??

    I’m not sure if it’s related but I’ve had something similar happen with (firewire) 2x 8-channel Presonus interface + windows laptop once. The main culprit turned out to be the fact that the laptop scans for wifi networks every minute or so. That seemed to stress the system so badly it caused processor spikes which in turn started noises in the recording.
    I will check tonight for the name of the little program I dl’d to check for this and let you knowm.

    No, a bad cable or USB connection wouldn’t sound like that. It’s surely within the computer. Something has changed over the course of time. And if it’s used for other tasks and/or has multiple users there’s every chance that something is/was over-taxing the CPU or causing interference from some shared piece of hardware.

    Any recent updates to the computer? Have you checked to see if there’s something running in the background that wasn’t before? If the live sound and the Qu-drive are both noise free it’s your computer for sure, especially if it’s a multi-purpose device which sees the internet with multiple users. If it’s a dedicated recording computer and your DAW/recording program hasn’t changed li’s harder to say, but these things DO age.

    Good luck tracking (sic) it down.

    Ok, I found the programs that helped me to tackle my somewhat similar problem:

    Latencymon: https://www.resplendence.com/latencymon

    CPU core manager from coderbag.com

    WLAN optimizer: https://www.martin-majowski.de (or defeat your wireless adaptoers alltogether while recording !)

    Following this thread –

    Have updated firmware – made no difference
    Have tried changing USB Leads – made no difference
    Have used garageband, quicktime and audacity – interference on all
    changed mics – no difference
    tried using multiple computers – no difference

    Seems to be a problem that is not being addressed or answered very easily. Please someone at A&H help. Looking at other brands now, as this is unusable.

    @cubecrazy

    have you tried different types of PCs from different makees with different operating systems and different drivers and different buffer sizes and with ALL the crapware deleted including any antivirus or similar type programs?

    Lots of things can cause this problem that I would look at before blaming AH.
