The Courtesy Call - Steam Audio Pathing Test

This is an OPTIONAL experimental test that includes the Steam Audio Pathing data. If you have this addon enabled alongside the other Courtesy Call addons, an option in the in-game settings menu will appear to enable/disable pathing.

This won't make everything sound magically better. In fact, only a few things actually use pathing. After playing around with it myself, I discovered that it can actually make a lot sound worse. The most noticeable places you can hear it work are the fizzler loop sound and Wheatley's dialogue after you fall in sp_a1_intro3.

• The further you move from the sound source, and the more complex that the pathing gets, the more it impacts your GPU frametime (for some reason).
• Sometimes, pathing can make a sound completely silent. This is another reason I don't use it for everything.
Keep in mind that I can't really solve these issues since the problem lies with how Valve implemented Steam Audio Pathing in HLA. I believe these issues, and some others I may not know about, are why pathing is disabled by default.

Having said that, here's a tip:
If you don't care about Steam Audio Pathing and want to save some loading time, you can add this to your autoexec.cfg or launch options:
