I recently got my Mustang Floor and am loving it except for one issue I have using Ableton. I will state right up front that I am new to this whole home recording thing. I have issues with crackling noise that comes up during recording. Initially all is well but after a while the noise comes in. This also happens with Reaper. If I shut the program down and bring it back up the noise is gone. If I then play the recording back the noise is not there. I have searched all over this forum and cannot come up with a definitive solution.

Here is what I am doing. The Mustang Floor is hooked up to my laptop via USB. I am monitoring sound through headphones using the headphone output jack on the laptop. I have used both the Fender ASIO and ASIO4ALL drivers and the problems occurs with both. In the ASIO settings I have the Mustang as the exclusive input.

I have played around with buffering a bunch I still end up with crackling. I have raised it to the point where the latency is bad, but the noise still comes in.

Since the noise is not in the recording, I am wondering if it is a playback/monitoring issue is in the sound card.

Any thoughts?

Check your pc resources... it seems like you have an overload, possibly cpu.

When you record just close everything else... especially other java and flash things, very very resources consuming. It is also a good practice that you have no apps that use sound running. This may also include browsers and media players.

Also keep the mustang channel volume on the low side, makes the recording quality a lot better!

I'll try running the Windows Performance Monitor and see what that looks like. Would getting an audio interface take any load off the cpu?

What are the specs on your laptop?

I use a laptop too to connect with fuse. When I'm connected to USB, there is a constant really annoying noise in the headphones or the speakers. I know the problem is with the laptop and his power supply. I'm also using wifi so I know all these things interfere with the Mustang. When I don't need fuse, I unplug the USB from the amp. I tried with a different brand of laptop and I don't have that noise. If I connect the laptop power supply in the same electricity outlet of my amp, I have interference too.

The idea here. Try to disable wifi and bluetooth on your laptop. Try the same using the battery. You may also try a different USB cable. You may also make sure you don't have a cell phone nearby the amp. A couple of weeks ago during a jam, the signer was near my amp and everytime there was activity on his mobile, it was interfering with my amp. That was really strange and we searched for a while to figure out what was the problem.

Thanks, definitely a few things to try. I have tried running on battery only and it didn't help. I will try plugging into a different outlet and try a different USB cable. I will also try disabling WiFi and Bluetooth.

Interesting thought on the cell phone. I almost always have it on the desk next to the laptop.

I'll try all of this tonight and report back.

Troubleshooting audio problems on Windows is a real boondoggle. As others have said disable EVERYTHING that's not vital to your audio recording. Reduce your video color pallet. When recording, disable video updates in your DAW. For example, don't have it draw waveforms while you are recording. Also, zoom out of the project as much as possible, so that the video doesn't have to redraw the screen. Make sure your video isn't sharing an IRQ with anything else, and the same for your USB hosts. Disable any scheduling in the O/S. Also, optimize your DAW for operation in the background (yeah, I know, it's counter-intuitive. What can I say? You're running Windows!) Open the taskmanager and see what all is running!! Got any virus programs?? If so - KILL THEM - many of the are HORRIBLE resource hogs!!!

You get the idea! It's not as easy as a one-click solution. It could also be related to your sound card.

If you are getting a whining noise..
Try unplugging your power and run it just on the battery. If that takes the noise away, then get a three prong to two prong power adapter and plug your power back into the laptop with that setup. This trick has worked on three of my laptops that had noise issues while using my laptop as a sound module for my keyboard and also recording with Reason 6.

A slow hard drive will screw it up as well, SSD's are getting a lot cheaper these days..
I always defrag my drive before a recording session, but not the SSD's, some of them don't like that very well.

My main recording laptop has two hard drives and the OS hard drive is an SSD and the drive I record to is a 7200rpm sata II. I am also using a firewire mixer most of the time, but I have recorded with a Zoom R16 that was usb and it worked fine. This laptop is a core 2 dou with 4gb's of ram.

If you are going to use your laptop for recording set it up just to do that. No other apps, just what you need to record with and set it up to run in server mode or background processes mostly. I don't run antivirus either. Cut off the wireless and anything else that is taking up resources and hardware time.

The laptop I use for my mobile video recording is an i7 with 8gb's of ram and a 7200rpm sata ii drive, but I am planning on getting a SSD for it in the future.

Firewire is king for recording and I use it on my laptops and my desktops for that purpose. If your laptop does not have firewire NewEgg has firewire express cards. I always try to shoot for the TI chip firewire opposed to the others. A good laptop firewire interface is a PreSonus FIREBOX 24-bit/96kHz FireWire Recording System if you can find one on eBay. They have replaced that one with the FireStudio Mobile.

WOW, so much good information here! Thank you everyone! Time has limited me from trying most of these solutions, but this weekend I plan to do so. I can't wait to get to the bottom of this. I have learned a lot from the replies. This forum is great resource. Thanks again everyone!

Well I have tried everything mentioned above and still get the crackling/clicking noise after recording a bunch of tracks. It does not show up when I render and it goes away when I shout my DAW (Reaper) down and restart it.

Did you check the laptop manufacturer's site for an updated sound card driver?

Hold on a second. You hear the crackling during recording, but NOT on playback, when listening to the track just recorded???

That is either a Windows driver issue, or your soundcard is having problems handling full-duplex.

The drivers are up to date. I think you could be correct about the sound card handling full-duplex. If I got an simple USB audio interface, it would solve the problem, correct?
