Audacity 2.1.2 and 64-bit operation

Greetings from Oz. I have used earlier versions of Audacity, mainly running XP Pro. Since upgrading to Windows 10, 64 bit operation, I find that Audaicty 2.1.2 gives broken, staccato, recordings. Will Audacity 2.1.2 run effectively on a 64-bit system? Can it do so? EA Bennett

You may be confusing two things. Win10 is not an “upgrade.” It’s a whole new system and your sound hardware has to be certified to work. “Works with Windows” doesn’t do it any more. It has to say certified with Windows 10. Further, the drivers and support software should come from the maker of the sound hardware, not plain Windows drivers.

So that may be where the bad sound is coming from, not the 32/64 divide.


I don’t see a pre-baked INFO packet about that, but that’s how I understand it.


I’ve got it loaded on a couple of Win10 64 bit systems (On one of the machines I haven’t actually done any recording.)

Anyway, it’s probably something else “hogging” the CPU and preventing the audio from working smoothly. It doesn’t have to be using-up a lot of CPU time, something (usually a driver) just has to hog the CPU for a few extra milliseconds and the recording buffer overflows and you get a glitch.

Assuming your drivers are correct and up to date, the next thing to try is to increase the buffer size/latency. (Edit → Preferences → Recording → Latency.) And, close any other applications and try to find out what’s running in the background.

It can get quite complicated, but if you can’t get it working and you want to dig into it, there is a [u]free online book[/u] about optimizing your computer for audio.

Audacity runs fine on 64-bit systems.

A common problem on computers that have upgraded to Windows 10 is that the sound card drivers need to be manually updated for Windows 10. The problem has been that the Win 10 upgrade does not upgrade the sound card drivers to the correct drivers for the sound card, but rather installs generic Microsoft Win 10 drivers. The generic drivers usually work OK for playback, but not for recording. See this page for details:

If you upgraded from XP to Windows 10 on the same machine, there may not be any Windows 10 audio drivers for your hardware. Check if out, but you could always buy an external USB sound card that supports Windows 10 and use that instead.
