So I'm trying to submit a song to the Audio Portal, but it won't let me upload the MP3 file I've created (see error below).
It is under 15MB and it is sampled at 44.1kHz, like the Portal requires. Here are a few other specs:
File Type: MP3 Format Sound (.mp3)
File Size: 586 KB (600,984 bytes)
Bit Rate: 128kbps (I've tried everywhere from 64kbps to 128kbps)
I created the file by exporting a .WAV from LMMS, then converting it to .MP3 using Adobe Soundbooth.
Any ideas as to what might be causing this?
