Audio error: file not recognized

Oct 07, 2022

I'm trying to upload an M4A file in Rise 360 and am getting an error that the file type isn't recognized. The file is well under the 5 GB size limit, is stored on my desktop, and the file name has no spaces, numbers, or special characters. Does anyone know what might be causing the failed upload?

An M4A file is an audio file created in MPEG-4 format, a multimedia container format in which compressed audio and video data is stored. It contains audio encoded with either the AAC codec (Advanced Audio Coding) or the Apple Lossless Audio Codec (ALAC).
