Can not upload audio with .mp3 formats

I am trying to upload mp3 audio just so i would be able to add time stamps on it but i am not able to do that, it uploads the audio but when i try to save it, the message in red under the audio appears that it is not supported format.

Could anyone help me out with it?

I have had this issue as well today. What I have noticed is, that if I download a Youtube video mp4 through Y2mate - Free YouTube to Mp3 & Mp4 Converter to a mp3 format and try to upload it in the lesson I get the same error. I tried re-converting the mp3 into mp3 again with and they all worked. Very strange how I have to double convert into the same format.


lol, it worked now that’s really weird, thanks for the help bro

it worked now thanks

Great, glad to hear it!

I’m also having this issue. I’ve emailed the file to the support email just now.

I’m using the site to create the mp3 file from this youtube video: Germans’ Favorite Life Hacks | Easy German 459 - YouTube

When I upload the mp3 file it says it’s not in a supported format. I’ve used the site many times in the past without issue, but potentially something wrong with what they are producing? It plays fine on my computer.

Thanks. I saw your email, we will look into it and try to figure out what’s going on.
