prompt "Save changes before closing?"

How to enable this annoying prompt?

Just open a mp3 file , check if there is no clipping - made NO CHANGES! - and have to click on this to be able to open a new file.
With 1000 files it gets old!

Presumably you mean “disable”. You can’t disable it, unless you modify the source code yourself.

We keep a track of comments, but the developers will not just make a way to remove the prompt without precautions. A precaution might be if you had exported all the audio since your last changes (if any).

Audacity does not do that. It decompresses the MP3 to PCM and stores that data.

You don’t have to click on “Save Changes?” to be able to import a new file into the same or a new project window.

As long as there are not too many files to import, which would eat up your disk space, click the button top left of a track to close it.

Just open a mp3 file , check if there is no clipping -

I’m going off-topic, but… A file can be normalized to 0dB, and the lossy MP3 compression will change the wave shapes, making some peaks higher and other peaks lower. It’s not unusual for the resulting MP3 to have peaks somewhere around +1dB. In that case, Audacity will show potential clipping, but the MP3 format is NOT hard-limited to 0dB and it may NOT be clipped.

If you decode that MP3 and send it full-volume into your DAC, your DAC will clip. But, I’ve never heard of a case where that kind of slight-clipping was audible… i.e. I’ve never heard of a case where there was an audible MP3 compression artifact, and that artifact went away when the level was reduced by a couple of dB… If you hear a compression artifact, it’s probably not clipping.

This is a good point, and I’ve been thinking of it since I started. No changes are made but the question is still asked. You aren’t keeping track of changes.
More patching work for you, sorry.

By the way I find this sourceforge site confusing. I take it we need to register separately for each project. Also bugs in the login process etc.

Audacity imports an MP3 into a project then that project has unsaved changes. Naive users often delete their MP3 or other files after importing them. That is what it’s about.

Audacity no longer has any relationship with Sourceforge.

There is no global Sourceforge forum. If there was it would be of unmanageable proportions.

Each project that has (or used to have) connections with Sourceforge have their own support methods.

Please do not make off topic comments. If you have something relevant to say about the login process on Audacity Forum, please make that comment here: Maintaining / Improving this Forum.

I do click the [X] button top left of a track to close it - and that results in the box popping up with the question “Safe changes” and this happens for every open audacity file on gthe desktop.

No it doesn’t, in Audacity made by us. See Audacity ® | Download for Windows.

Drag in or File > Import > Audio… a file, click to left of the track name (to left of the red oval in the image below):

This closes the track and there will be no prompt.

Then drag in or import the next file.

There will be one “Save changes” prompt when you close the project window or when you quit Audacity.

This is it. I can import 32b-fp, make no changes, and always get that question.
