My friend and client, Brian Selke, is one of the best Windows techs I know.
(He’s actually teaching a class on how to stay safe as a Windows user…more details soon.)
He ran into some issues getting his AT-2020 USB Plus and Audacity to record cleanly and smoothly on his then-new Windows laptop, and as usual, he wouldn’t rest until he figure it all out.
If you’re having issues getting your mike and software to play nicely, this article is going to be very helpful.
It started with a stuttering when playing back, which turned out to be a stuttering when recording – not just in Audacity, but in any piece of software he tried. And it was with any USB mike he had, most notably, the mike we recommend, the AT-2020 USB Plus from AudioTechnica.
And it started happening when he’d upgraded to Windows 7, and continued in later upgrades. He thought it might be a buffer issue – the buffer being where data is stored until the computer can handle it – like when recording a steady stream of audio.
Turns out he was right.
So, Brian started talking with AudioTechnica, and researching user forums for Audacity. Then, he found the answer.
(Truthfully, he did a lot of legwork that’s saving you and me time and frustration. You might thank him the next time you see him.)
He got a note back from AudioTechnica when he asked if they’d seen problems like this with Audacity. Here’s what they said:
To be completely honest, this is the first I’m hearing of the issue you speak of as it relates to Windows 7. Although we do not manufacture Audacity, we do give limited support.
Most of the time, when one is experiences buffer issues, this is due to the hardware used and the amount of work the computer processor is doing. When recording, it is recommended to shut down all other programs and only use Audacity. This way, CPU is allocating all of its resources to Audacity and processing the USB audio signal.
Some additional tips on making certain you are operating properly with AT2020 USB mikes:
1. Make sure you are not connecting multiple USB audio devices to your computer at the same time. Currently, computers can only recognize a single USB audio device at a time. If multiple USB audio devices are connected, you will need to disconnect all other devices in favor of the one you want to use.
2. Try a different USB port, and see if that fixes things. Sometimes computers apply different amounts of power to different USB ports.
3. Try a different USB cable. The quality of USB cables varies; if you elected to purchase the bargain brand, you might experience bargain results.
4. Make sure your computer is fully up-to-date. This includes your OS, your drivers, and any subsequent programs/software. (Brian adds, “And make sure the system BIOS is up to date.”)
5. Try a different computer to verify the issue. If it works on another computer, then you know you have some work to do with the first computer.
6. Avoid USB 3.0 ports, USB Hubs, and USB inputs on computer monitors. All are known to have issues with USB Audio Devices.
Since you have stated that this is happening with Audacity and not with the built-in recording application, you might ultimately need to consult Audacity’s help page. There is also not an included driver to update. However, the attached document might help to update the driver supplied by Windows 7 and/or the soundcard.
Hope this helps!

Brian also reminded me that USB microphones like and need steady voltage. He also advised me to make sure that Audacity is up to date, as well. You can always get the current version here:
So what eventually solved the issue? A powered USB hub for him, but this might not be the same solution for everyone.
