I was looking at env_soundscapes for Source, and I learned some new things about how they work. All their features aren't too different from ours, but they have some neat stuff we should probably implement for compatability and just because they're useful.

  • dsp
    You can specify env_sound types here, uses a number but we can specify the full name. Aso comes with a volume control. This cuts out using env_sound if desired, which I agree can be useful and helps optimize/streamline.

  • playsoundscape
    This allows you to load a soundscape with a soundscape, this is how they get "layers" in soundscapes. It seems you could load as many as you but I'm sure there is some limit. "DSP presets in the 'sub-scape' are ignored."

  • playrandom/rndwave
    We do random sorting already, but it seems they don't by default? rndwave might have a counterpart for playing a list of sounds in a sequence

  • time
    Used for delaying a set of sounds that play

  • position
    Allows sounds to be played in different "areas", need to investigate how this done, the effect might be just channels or have spatial properties

  • attenuation
    How quickly sound drops off from the area

  • soundlevel
    An alternative to attenuation, but why?

Entity documentation, not asking to implement these, at least not until we really have to because they're is just soo much :x

Also here is a snippet from soundscapes_trainyard.txt:
