Audacity Forum

I have an mp3 of the audio from a movie. It is over an hour long, but plays fine on windows media player. But when I try to import it into Audacity, I get about 15 seconds of pure squeaking noises. Any suggestions? (I'm trying to add some silence to the beginning of the mp3 so that it matches the video file I have better; otherwise the voices won't match with the scenes). By the way, I have windows 7 and Audacity version 1.2.6.

That's exactly what happens if you try to import an unsupported file type, so my guess is that your "MP3" is not a real MP3 format file, but some other unsupported format.
Try downloading 1.3.12 from download page. Then install FFmpeg

Okay, I installed 1.3.12 and ffmpeg, but I still get squeaking noises, so I'm guessing it's an issue with the file. I used mkvextract to extract the audio from an mkv video, and got a file called "track2file.aac". I tried changing the file extension to mp3, which seemed to work using windows media player, but gives the squeaking noises in Audacity. Do you know how I can get the track2file into a legitimate, working mp3, so that I can edit it?

Thank you for your help.

Changing the name does not change the format. It may work with Windows Media Player, but WMP is weird

Try changing the file extension back to .aac and see if Audacity can import it.

Thank you so much! That worked!
