Ever since the update, any time a GUI update comes up for the bottom of the screen (like every second counting down on a map vote from sourcemod or whatnot) causes this ANNOYING "Schweep" noise... theres no way to even spell it, literally, its so completely fubar.
I've come up with 2 fixes, this one completely removes the sound (replaces with 0.001 second long -160db sample). The other replaces it with a techno-bassy filter added onto the original sample at a different velocity.
LOL you sir are a retard... This one has a preview because it has a sound, the other one doesnt have a preview because it's a 0kb file that has no sound (Why the fuck would I put a preview when theres no sound? lol)... If you knew what noise this was replacing, or just read both posts, you wouldnt have wasted your time. So yeah, delete your post, cause you're not very smart.
