As of now, Audiality is mostly off-line modular synthesis along with a 
basic sampleplayer (DAHDSR envelopes, FX sends etc) and a few real 
time "effects".

So far, it's really been focused on creating sounds from "nothing" (ie 
no samples), though it can import, play and process sampled sounds as

Yes and no. The most current release is probably the "unnamed" sound 
engine of Kobo Deluxe, though I'm just keeping it alive as I'm still 
using it - no real development. (As of 0.5.1, all sounds are pure 
modular synthesis - no samples.)

The plan is a major rewrite, using EEL for scripting (setup, real time 
control processing etc) over a properly modular DSP engine (possibly 
usable as a stand-alone library, without EEL), including 
modular "massively additive" IFFT synthesis.

The goal is to make it all modular, all the way from control data 
through audio outputs, and optionally off-line/real time, so you can 
have a "module" adapt to available resources, project requirements, 
user preferences etc.

Think evolved MOD format, including proper sound effect support. You 
load up a module, which exports a bunch of controls and triggers 
defined by the module author. Like connecting a studio sampler to the 
MIDI port and have the "sound guy" programm away on that - only you 
actually ship with that thing included with the game.

When? When I get around to it... :-)

Couldn't FMOD or some other popular "game sound engine" do this? I 
know most of them have sample playback (obviously) and effects, but I 
don't know how flexible they are when it comes to wiring things
