hey everyone, new user here, my problem is and I tried to solve it, but I didn’t yet, that when I drag my audio file (mp3) which it length 4:40 min, it compressed and being really fast up to less than one sec, to 0.45 sec, that’s really wired, and I didn’t find anyone like my problem, which is strange, so can you tell me what’s the problem and how I fix it?
thanx and my regards 
Audacity can do that if it doesn’t understand a sound file, which means chances are really good it’s not an MP3.
You can download and install the FFMpeg software package which will allow Audacity to open up many more different found formats.
This is the software for Audacity 2.1.2.
Scroll down to Optional Downloads.

That’s also the link to download Audacity 2.1.2 if you need it.
