Detailed description of the problem I've discovered that audio files with a bit rate of 160kpbs will not actually load into Roll20. It will seem like it's loaded, but no waveform will be generated and the tracks will all have a length of 0. The solution is just to upload files at 192kbps or maybe other bitrates, I'm not sure, but 192 works for me. If this is intended and 160kpbs are not supposed to be allowed, I feel like a warning would save people a lot of headache and frustration. Thank you for reading. Minimum number of steps to reproduce the problem Upload any 160kpbs audio clip to Roll20. What I used was an extension called Blue Convert to convert some youtube vids to audio and I downloaded the audio at 160kpbs. Description of setup Chrome + Chrome 83 .
