Audiomass has trouble loading up an hour long audio clip, but can upload a 3 hour long audio clip without problem!

Ok, I don't know if this is related to my device (considering I AM doing this on a Chromebook and Chromebooks are pretty much total shit in terms of hardware performance!) Anyway, when I attempt to upload an hour lng audio clip, the entire program (and my computer) freezes, forcing me to restart my computer! But I once tried to upload a 3-hour long audio clip from the same device and that was successful! So why is audiomass failing to upload a 1-hour audio clip, but can upload a 3-hour audio clip?
