Some of the most useful soundsets, I’ve found, are the basic stuff, just done well, and in variety.
In particular, as PCs travel through various types of countryside, it’d be nice to have that ambiance playing. Swamps, mountaintops, and jungles are covered, but general countryside (a settled area) aren’t particularly.
For forests, in all the soundsets there are only Witchwood and Elven Vale Night and Day. (There is also a “Forest Day” and “Forest Night” in “Classic Adventure.”)
But the sound elements in these overlap, or sound like they do quite a bit–so we end up having a forest that sounds quite same-y and using wagon journey for general travel.
Same limitation crops up for sounds of thunder.
Rain is an example of what I’m asking for done well–the Elements - Rain soundset has nice variance.
What’d be fantastic would be some more of these heavily-used soundsets in greater variety. Personally, I’d use those much, much more than the complete adventure soundsets put out for Pathfinder and D&D.
Thanks for your consideration.
