Audacity has quit unexpectedly.

This happens every time I quit Audacity correctly. I have an iMac 2.8 GHz Intel core i7, OS 10.6.8, 8 GB ram. This never happened in previous versions.

Do you get a dialog offering to “send a report to Apple”? If so, copy the first 20 lines or so from that dialog and post them here. Don’t bother sending it to Apple.

The crash is not in Audacity per se, but in an auto-tune Audio Unit Effect. Removing that effect will probably remove the crash.

Audio Unit effects are stored in:

Find the auto tune component and move it somewhere else, such as the desktop.

Thanks Bill. I found the auto tune plug ins. if I remove them, I’m assuming I won’t be able to use them with Audacity. Does that also mean i won’t be able to use them with Digital Performer, which i also use? I haven’t experienced a crash in DP. Should i upgrade autotune? Is the file itself corrupted or just reacting badly with Audacity? Should i use my previous version of Audacity since it didn’t crash?
Again, the “quit unexpectedly” didn’t happen until after I quit Audacity myself.It seemed to be ok when I put audio in the program.

Yes, if you remove them they won’t be available to any other program.

I’m guessing here, but it crashes in FxDisposeBitmap. Try unchecking “Display Audio Unit effects in graphical mode” in Preferences > Effects and see if that helps.

I don’t know what has changed in 2.0. What “previous” version of Audacity were you using? The developers might be interested in tracking this down.

Further to Bill’s post, was your previous Audacity version 1.2 something? That would not have the problem because it would not recognise AudioUnit plug-ins.

There are several other things you can try if Bill’s suggestion doesn’t help.

AutoTune probably won’t be fully functional in Audacity, anyway, but updating AutoTune and seeing if that cures the issue would be a good idea. Please let us know if it helps.

If DP has preferences, see if you can give it a different location for Audio Unit plug-ins (or specifically for AutoTune) than the two locations Bill mentioned where Audacity looks.

If you don’t want any AudioUnit effects in Audacity, then you can avoid moving AutoTune by disabling AudioUnits in Audacity. To do this, quit Audacity or let it crash, then go to ~/Library/Application Support/audacity/ and copy in the attached after renaming it to “audacity.cfg” (without quotes).

Also do you have the VST version of AutoTune and could you use that instead of AudioUnit? It is possible Audacity would not trip over the VST.

Thanks for all the responses. I was using Audacity 1.3.12. I opened 1.3.12 and quit the program and the dialog box did not come up as in Audacity 2. Again, this only happens when I quit the program correctly either through the Audacity menu and choose Quit or use Command Q. I haven’t put Audacity 2 through much work so I can’t say if it will quit when I am using the program. I have Autotune 5 so it’s definitely time for an upgrade. I should do that here shortly. I’ve never used Autoune in Audacity so disabling AudioUnits is probably not a bad idea. I’m not sure, off the top of my head, what other plug ins use AudioUnits in Audacity. I mostly use the program as a 2 track editor.

Disabling “Display Audio Unit effects in Graphical Mode” did not stop the dialog box from happening when closing the program. I disabled AudioUnits in Preferences/Effects and closed the program. The dialog box did not come up so there is certainly a conflict there. I will upgrade to AutoTune 7 and let you know how it turns out. Thanks again everyone.

Thanks Paul for the input. It’s interesting if you have Audio Units enabled, disable them in Effects Preferences and quit, then it doesn’t crash when unloading the Audio Units.

Are these crashes on quit always only if the project window is empty when you quit? Is this a 64-bit machine?



I have an iMac 2.8 GHz Intel Core i7 so I believe it’s 64 bit but I’m not sure. I bought it in January of 2011. The crashes on quit happen if I have audio in the program or if there is none. I’m not sure why it happens now and not in previous versions of Audacity.I’m hoping my upgrade of Auto Tune will eliminate this problem. Gotta check my finances…


Downloaded Auto Tune 7 and installed it. No crash on quit! Problem solved. Thanks all!

Thanks for letting us know, Paul.

Does the Audio Units Auto Tune 7 work (after a fashion) in Audacity, or does Audacity ignore it?
