Audacity Forum

Hi, first post. I've been editing our podcasts for a year and all of a sudden the first podcasts of 2021 and I can't get the music (mp3) files to load into audacity. I've tried reloading the Lame and FFMpeg libraries and nothing. HELP!!!

There was a change that makes Audacity more picky about imperfect MP3s... They fixed one problem but then it turned-out that there are lots of "invalid" (but still working) MP3s floating-around....

Until that's "corrected" there is a work-around using FFmpeg.

Awesome!!! Many, many, thanks! I was going crazy!!

Uh OH! Now I can't upload MP4 files like I used to. I get a different error now. Is there another rule I need to make that work now?

"Upload"?
Do you mean "Import" into Audacity, or "Export" from Audacity, or something else?

I get a different error now.

What is the full and complete error message?

Sorry, normally I drag and drop my raw mp4 files into audacity. Now I get an error stating that it's "an advanced audio coding file. Without the optional FFMpeg library, audacity can not open this type of file.

Look in "Edit menu > Preferences > Libraries".
Which version of FFmpeg does it say you have?

Lame MP3 Export Library version: 3.1 (built-in)

Please try this:

1. Exit Audacity
2. Restart Audacity
3. "Help menu > Diagnostics > Show Log"
4. Copy and paste the contents of the log into your reply.
