Yup, by quite a bit I’m afraid. The Syrinscape Soundset Creator does compress files but if you look at one of our original content soundsets you will see that they very rarely pass 70mb. Remember the Syrinscape functions much like a mixer, playing multiple sounds at once. If a soundset is to big then it will really slow down the process.
Have a play around saving your files as Wav’s or Ogg’s, cut down the number of long music tracks and divide your soundset into multiple souundsets, like the Soundpacks we release for the AP’s. That way you might have to flit between two or three soundsets but you will have all of the content that you want/need.
