100mb is the maximum size for a soundset rather than an individual sample. A 30 minute sample will be rather large and most likely the reason it’s failing.
When you are uploading any samples, music or sounds you are much better uploading each piece individually so that Syrinscape can then play those samples randomly. If you upload all of the music as one sample then it’s just going to loop it, which will become very repetitive at the table.
So I would suggest that you;
- break your sample down into smaller tracks
- Make sure the samples are 44k,16bit (cd quality) was files
- Make sure all meta data is stripped out
- Keep the total size of the soundset to be less then 100mb
Our soundsets are normally between 50 to 80mb, which should give you a good guide as to how much you can fit into a single soundset. The “Shadows of Esteren - Dearg” soundset has an entire album plus ambience
