Can not add audio

I keep getting this message:
We support Images (JPEG, PNG, GIF), Videos (MPEG, AVI, WMV), Presentations (PPT, PPTX) and PDF.

Hello @Melissa_Pearson, what file format are you trying to upload? Can you please also test it in different browsers?

Thank you for replying. Luckily I was able to contact support and I had to use a file converter to upload the file.
