Sure.
Most of the sound effects currently have a reverb or echo effect in them. Sound effects with reverb are only applicable to a small set of environments in the game. There may be several environments where reverb is appropriate, but they each may need a different level (or type) of reverb. It is fairly easy for us to apply an appropriate reverb to any environment-neutral "ambient" sound effect, but removing reverb from a pre-rendered sound effect is nearly impossible. For this reason, we will eventually need a version of each sound effect with no reverb at all.
Many sound effects seem to have a muffled effect, as if the player is hearing the sound through a wall or thick barrier. For example, some of the hammering sound effects don't sound like an actual hammer, or they sound as if a low-pass filter was applied to them. Some other effects have some broadband noise in the background. The noise is not always apparent, but in a game environment it becomes obvious that it doesn't belong and can be very distracting to the player. Ideally, we need sound effects recorded in a place that is as acoustically-neutral and noise-free as possible with no filters and no environment-specific after-effects. For instance the sound of "gobling screaming
in a cave" is not as useful as "goblin screaming". We can always add after-effects later as we need.
Let me know if you need more specific information.
