How to simply trim/cut MP3s and save as MP3?

"QT can trim mp3 files but when they are then saved they are put inside a QT .mov file wrapper."

Is it possible to get rid of this ".mov-wrapper" so I can simply SAVE an edited MP3 as MP3 without re-encoding it?

Daniel, welcome to these discussions.
Do your edits to the .mp3 file using QT Pro and export the file to AIFF. This will over sample the file (record will data that doesn't really exist in the original).
Add the file to your iTunes library (Command-O) and then use the "Convert" under the Advanced menu.
Make sure your Import settings are set for MP3 encoding (to retain the .mp3 extension) and that they are the same as the original file.
Delete the .aif file from your iTunes library.
Yep. Too much work for the benefits. But it does work.

well... thanks for this tip. But that's twice the conversion to MP3 (because I get MP3s from somebody already - then have to cut some stuff out).

But I'm a little bit confused why a program I paid for (QT Pro) isn't simply able to "cut MP3" leaving it an MP3 as it is 😟

Nobody else any idea?

Quicktime is not re-encoding the mp3 but rather is saving the encoded file inside the .mov wrapper. You should notice that the save is almost instantaneous and you would never see that if any kind of encoding were occuring. Encoding is time intensive.
Actually, Quicktime does not "Save" anything in its original file structure unless that file structure was .mov. It creates new material in non-mov format only by "Exporting" it

You might want to take a look at Audacity, a freeware sound utility that can be extended to encode mp3 files: Audacity
