TL;DR - Stonesense, as far as my involvement has been concerned, is about experimenting with, testing, and providing interface features for players that would help the general gaming public get into and enjoy DF, without causing additional work or stress to Tarn. Do you think you, or the general public, would get more enjoyment out of DF with limited sound, and why? If so, in what way do you think it'd be best to implement sound, and what would you like it to do? What would you like it NOT to do?
I would vote no sound, because Stonesense is a visualizing utility, and there's no reason for a visualizer to have sound. I think if you were to have sounds from DF that reacted to the game, you might want to take it up with toady.
Stonesense is like a patch to fill in the gaps in DF's current user-end functionality. Tarn is very busy on the features and gameplay of his project, but many people are kept away from supporting and enjoying it by the seeming crudeness of it. This is the reason people use external utilities, like Stonesense. The question I am posing is this: what other features (in this case, related to sound and music) would people like to see implemented in DF?
If people are opposed to sound because they think it would cheapen their DF experience, that's a great thing to take into consideration. If Japa, Jonask, Peterix, or any other contributors think that the difficulty and/or the limited scope of implementing it would outweigh the benefits, that's a good thing to think twice about. To oppose it because Stonesense is referred to as a Visualizer, or because Tarn hasn't implemented sound, is entirely silly... most everything Stonesense does hasn't been implemented yet.
The point of the Stonesense project, as far as my involvement has been, is to design something that can run paralell to DF, and add generic user-end features that Tarn presently doesn't have the time to play around with or consider. This may include reporting and logging information, viewing multiple layers of construction, or things not capable of being displayed by ASCII characters, and adding other elements that further the enjoyment people get out of the program. In the end, I hope we can provide an example of a display/interface for DF for him to consider when he gets to that step in his design process, and in the meantime improve my own digital art and interface design knowledge.
So yeah, in summary what features (specifically related to sound) do you think would help or harm the enjoyment you get out of DF? Would you benefit from a randomized song playlist, or perhaps one that played music based on what's happening in the game? Would a simple ambient sounds of running water while viewing a river, or a hollow dripping echo as you explored caves in adventure mode make you happy? Would endless "YOU HAVE STRUCK MICROCLINE!" fanfares drive you into a fell mood?
