    I've actually put up with this for ages without bothering to ask what it is. When I'm playing guitar/bass/keyboard through podfarm, roughly every minute or so there is a really annoying 'pop' noise, so you have to do take after take to get something recorded and hope that it doesn't happen on one of them.

    Anyone else had this or heard of it?

    Sounds like you need to increase your buffer size...
  4. avatar fletch_belfast
    I shall try that, just as soon as you explain how :024:

    Hey.

    It depends what sound card you're using - is it your computer's built-in sound card, or are you using an external interface as your sound card e.g. are you using one of the line 6 ux1/ux2 devices? Mac/PC?

    Your soundcard's software should allow you to tweak the buffer size - you might see values like 128/256/512/1024. This dictates the size of your buffer - if you make this too large then you might start to hear a bit of latency while you're playing. You might just about get away with 512 samples. Anything larger and you'll get a delay (this is fine for playback but not for real-time input).

    You might also want to check out this tool -> http://www.thesycon.de/deu/latency_check.shtml, if you're using a USB or Firewire interface/soundcard. This utility might show you the large 'spikes' every minute or so - what's causing those spikes is another question entirely (it could be just about any device on your computer)!

    Anyway, good luck.

    I'd reckon buffer size as well. You need to open your ASIO control panel - probably in your DAW. In Ableton Live, there's a "hardware options" button in the audio preferences pane - I can open it and set buffer size and bit depth for my interface. (If you don't have an ASIO driver, find ASIO4all and try it.) Increase (double) the buffer size until the dropouts / glitches stop. You may need to track dry at lower latency (smaller buffers) and use the plugin with higher buffer sizes after.

    If that doesn't work... Are you using Pod Farm 2? It's still new and I expect there'll be another few revisions before it stabilises - I was seeing the dreaded BSOD with the first version I tried, eep!

    Best,
    Russell

    If your using one of the toneport UX1/2 etc interfaces, they do have an issue with the usb ports on certain motherboards for some reason, it used to happen on my old laptop no matter what the buffer size. IIRC theres no way t resolve it without using a different computer
  8. avatar steveginger
    Aye. If you've got a UX2, go to the control panel and you should see something like Line 6 Audio-Midi devices. Open that and tweak the buffer settings there.

    As noted though, issues with USB (and Firewire) interfaces for audio are very common on Windows PCs/laptops, with most audio manufacturers only support certain chipsets etc. If you're using a laptop with an express card slot it might help if you use a USB adapter, rather than plugging the UX2 straight into one of the single USB slots (I've had some success with that in the past).

    If you run the DPC latency checker, and it shows spikes that correspond with your experience, in theory you should be able to narrow down what's causing your problem - it may mean disabling a device or process. It can be a major pain in the @ss to track down. Worse case scenario is that you need something like a bias update, which never comes (like me!).

    Cheers.

    if you have downloaded it illegally, the companies put a pop in the playback, just like a watermark on a picture. Happened to me using a macktron.

    It happens with legally downloaded software that you haven't run authorisation software on - the IK multimedia amplitube stuff comes to mind. It's unlikely in this case 'cos there's a version of pod farm bundled with most of the line6 hardware...

    I'm using a UX2, plugged into my Dell Dimension C521 PC, my copy of Pod Farm (1) is legit.

    If I open Pod Farm and set the buffer size to 'extra large' where it says "Tonedirect & USB Audio Streaming", it seems to make a difference (the cracks become a lot further apart), but I think I'm losing sound quality when I do this. The latency only changes by a few milliseconds when I change that buffer size.

    My 'default bit depth' is set at 16bit, but would 24 or 32 not be better..? (under the ASIO settings)

    Is this whole 'buffer' thing not to do with RAM? If I buy more RAM would this problem just disappear? My Dell specs are:

    AMD Athlon 64 X2 Dual
    Core Processor 3800+
    2.00 GHz, 1.0gb of RAM (I think it could take 4gb...?)

    [quote:62625badad="fletch_belfast"]Is this whole 'buffer' thing not to do with RAM?[/quote:62625badad] Not really. Because everything is happening so fast, you only need the buffers to store a few milliseconds-worth of samples. You have thousands of times more actual RAM than that.

    [quote:62625badad="fletch_belfast"]If I buy more RAM would this problem just disappear?[/quote:62625badad]Possibly! For the unrelated reason that Windows might run a bit faster.

    You should also have an option to change the ASIO buffer settings, above "Tonedirect & USB Audio Streaming". What's that set as? 128? 256?

    Are you using Pod Farm in standalone mode, or are you using it as a plug-in in some other DAW software?

    "Bit Depth" refers to how accurately you capture your audio e.g. you can record at 16/24bit etc, and this is normally set in your DAW, so Id forget about that concept for now. It's the "resolution" of the audio capture.

    I wouldn't throw your money away on RAM just yet, unless you're rich and you don't care. Also try disabling wireless, infra-red, bluetooth devices on your PC.

    Or just go to the pub for the weekend and get pished, and hope a pixie fixes it for Monday.

    I think the default was 512, 16 bit.

    Whether I use it by itself or within Cubase, it seems to behave just the same.

    p.s, what's the difference between processed, semi-processed, and dry input....?

    512/16bit is fine, although 512 is probably going to add a little too much latency for some.

    Recording "dry" means the UX2 is sending your guitar signal straight through to the DAW (Cubase) without any processing. Semi/processed means you're probably adding some amp modelling and FX on the way in, although I don't know the specifics (I haven't used amp farm).

    Your best bet at this stage is probably to go to the Line 6 support site - http://line6.com/community/community/support - type "pops and clicks" in the search bar and just have a look at how many results are returned. There are a lot of people feeling your pain. Have a read through and try tweaking/disabling everything mentioned.

    I've been through this crap with every USB and Firewire device I've owned, and sometimes there's just no easy solution for certain PCs/laptops (just check out 'DPC spikes' on the Dell support forums).

    Anyway, the pub's open now...
