This occurs to the point where it can seem like the script has crashed. Is there something we can do about minimising load time, or providing some feedback to the user to let them know everything is ok?

To minimize load time, both should be kept to the minimum possible (particularly file sizes). In concrete terms, with MP3s, it may be unnecessary to use very large files encoded at 320kbps -- depending on what kind of sound you are displaying, a lower bit rate (e.g. 64kbps) may be sufficient. Particularly for voice-only stimuli, 32 or 16kbps may provide sufficient quality, resulting in greatly reduced file size and faster loading. As of right now, it is unfortunately not possible to provide feedback on download progress. You could, of course, alert participants to expect some load time / apparent freezing via instructions on the experiment's launch page. Hope this helps.
