Audio in slow motion

Why is it that often after I close Audacity, every audio that I try to play, be it on Youtube or on my Winamp, sounds like someone is playing an audio tape on an extra slow tempo? The problem gets fixed after I restart my puter. But why is this?

I have the same problem. All my mp3 files play slow from iTunes after Audacity loads. (These mp3s have always played fine before I load Audacity). Even after Audacity is closed and the Audacity process is not running, iTunes will play things about half speed. It will goes away after I reboot. Thanks for all your efforts. Great editor…does just what I need.

We can’t get to the bottom of this problem until we find the common attribute.

Can you two (and anyone else with this problem) post some specs for us? Which version of Audacity? What kind of sound card? What drivers? Which version of Windows?

I get this problem as well: when I open audacity, all audio on my computer suddenly sounds slowed down (including things like windows beeps, mp3 playback etc). Rebooting is the only way to fix the problem. Very frustrating. It happens in both 1.2.6 and 1.3.3 versions of Audacity.

I have a Toshiba Satellite laptop with the Realtek AC97 Audio driver. It used to work fine, but I’m not sure when the problem started. It may have coincided with installing drivers for my M-Audio Firewire 410 interface. I don’t have the same problem on my desktop computer (although I don’t have the M-Audio software installed there).

I’ve tried playing with all the preferences in Audacity and nothing seems to fix it. Hopefully you can track down the issue. I really miss having Audacity on my laptop!!


dmarks, the Drivers for your M-Audio device allow you to change the sample rate of the card (at least, the drivers for my 1010LT do). While everything is working right, open those drivers and finding the sample rate settings (I can’t remember which menu they’re in, I’m at work). Take note of which sample rate the computer is set to right now. Now, open Audacity to get everything slowed down, and then go back to the driver menu and see if the sample rate has changed. Can you then close Audacity and reset the sample rate? Does that help?

We still don’t know why this problem occurs, but it’s got to have something to do with sample rates.

I just had the same problem. I opened Audacity (1.2.6) , imported a mp3 and then played this mp3 and it was really slow.
Afterwards I noticed that if I play videos with Youtube, Youku, … they are also all really slow.
ITunes however still succeeds to play sound on the normal speed (for example also the mp3 that I imported in Audacity).

These are my Audacity settings:
My mp3 file was also 44100

Another weird thing is that now all of a sudden all my windows beeps are enabled, this also wasn’t the case before.

I noticed another thread about a similar problem:
and there it is mentioned that the problem is fixed when the original program that became slow is closed and reopend. That doesn’t work for me. All flash based applications are still really slow in my browser.

Sorry for the mini-rant (below), but I’m rather frustrated, I already have been looking for this problem for a couple of hours:
I really can’t understand that this critical bug still exists after 2 years. This is the kind of bug which will result in people abandoning the software and telling everybody you should never use it ever again.
