Audacity 2.1.0 records 1/2 speed?

Hi, all,

Windows 8.1, Audacity 2.1.0.

I’m a long-time Audacity user (very basic features) and have a problem that has me stumped: When I record, the recording process seems to go at half-speed, i.e., the time in recording mode between the one-second markers takes about 2 seconds. Then, of course, the voice playback at normal speed sounds like The Chipmunks. Tried everything, no joy. Can anyone assist me here?

Thanks in advance,

The current version of Audacity is 2.1.2. You can get it from us at

We would need to know exactly what you are recording, using what recording equipment (makes and model numbers always help) and how that equipment connects to the computer.

Something like this is usually a sample rate or driver problem. There is some general information here about things you can check for:


Hi Gale,

Thanks for the tips.

I just updated to 2.1.2.

I’m recording voice from a cassette player through a Foucsrite Scarlett 212 interface into a USB port into a Win 8.1 computer. I’ve made many many recordings this way (no changes to the cabling) and it’s all worked fine. Today when I fired it up, this nutty apparently “slow” recording took place. Sample rate is 48000. No changes to settings from the fresh installation.

When I monitor what leaves the interface to the computer, audio is fine <<<<<<<

Looked through the FAQ’s - didn’t see anything close to this…

What could cause this? I don’t see a setting that would affect it. Playback is set at 1.0.

Thanks for helping,


Hold the Windows key and press X, then Shut Down. Wait a minute or so before powering on. This is the equivalent of a cold boot which will give you a new kernel session.

If that does not change anything, it is presumably a mismatched sample rate somewhere.

I assume you mean the Audacity Project Rate bottom left is set at 48000 Hz. If so, and assuming you are using MME host in Audacity’s Device Toolbar, right-click over the speaker icon by the system clock, then choose “Recording Devices”. Right-click over the Scarlett then choose “Properties”. Then click the “Advanced” tab. Set “Default Format” to 48000 Hz.

If you need to use another host in Device Toolbar, then both Exclusive Mode checkboxes should be turned on in Windows Sound underneath that Default Format box.

You should restart Audacity after making changes in Windows Sound.

If that does not help, try 44100 Hz bottom left of Audacity then make the same changes to match 44100 Hz for MME host in Windows Sound.

If you are using SHIFT + R to Append Record into the same track, try without doing that.



Hi, Ray here…I restarted windows twice and then did a cold reboot - all is well now!

Thanks for the help!!!
