Weaver Audio
Klondike with ten editable events. A gentler place to start: few enough sounds to hold in your head, and the interference between them is obvious within a hand or two.
A character, seven animations, and a track of sound events under each one. Drop your own recordings onto a frame or stretch them across a band, then move them and listen: the same footstep is wrong two frames off the contact.
A wall between you and the gunfire. Duck behind cover and the enemy's shots filter and fall away, look elsewhere and they fall further, let him close the distance and they grow — with every occlusion, distance and focus parameter on a slider you can move while he is still shooting.
