I'm back! And I now use cool kids software like audacity and FL studio! Super duper hyper advanced stuff, yeah.

"Hello, and, again, welcome to the Aperture science computer-aided enrichment center. Over the course of the last few of years, a test subject diagnosed with dementia was tasked with completing tests as their condition worsened and got more severe. Their scans of brain activity after the completion of each test were used to form an orderly graph, detailing the progression of the disorder. These graphs were then utilized to generate a precise auditory computer simulation, which is what this next test will be about: How test subjects react while listening to an auditory depiction of a mental disease which slows and eventually stops your brain's ability to think, learn, and remember. The testing will begin in three two o-" *bzzt* "Just kidding, you may start whenever you feel ready"

Stage 1
"The test subject exhibits mostly normal behaviour, on rare occasions forgetting a previously discovered piece of knowledge or where they were headed. Euphoria levels for test completions are high."
00:00:00 A1 - It's Just A Deleted Memory
00:03:03 A2 - Late Afternoon Testing
00:06:02 A3 - Childishly Fresh Turrets
00:08:47 A4 - All That I Made Up Is True
00:12:25 A5 - Things That Are Musical And Spherical
00:16:01 B1 - A Machiavellian Equinox
00:18:53 B2 - Quiet Control Group Rebellions
00:22:04 B3 - The Love Constructs of My Entire Life
00:25:47 B4 - Into Each Other's Chambers
00:29:16 B5 - My Circuit Will Be Called In Courtesy

Stage 2
"The symptoms worsen from the first stage, but the subject tries to negate the adverse effects by putting more effort in. Efficiency of test solving suffers a mild setback, and euphoria levels for test completions are much lower."
00:30:40 C1 - Something Is Wrong With My Mind
00:33:46 C2 - Memory Vitrification Order
00:36:47 C3 - The Battle Starts With This
00:39:52 C4 - Disordered Evening Testing
00:43:12 C5 - Minor Case of Serious Brain Damage
00:46:07 D1 - I Still Don't Feel Different
00:49:14 D2 - Pure Recall Difficulties
00:51:51 D3 - Machinery Unravelling
00:54:32 D4 - What Does It Matter How My Circuit Crashes?
00:56:16 D5 - Long Lament Ahead Feels Lonely

Stage 3
"Symptoms get so bad they can no longer be neutralized with more effort, and as the test subject realises this, they adopt a much more hopeless mindset, slowly giving into their condition. The subject often forgets basic mechanics such as picking up cubes or flinging through portals. Occasionally, they stop testing for a couple of seconds, observing their surroundings, as if for the first time."
00:59:07 E1 - Back There Bach
01:02:27 E2 - And Circuit Crashes
01:05:18 E3 - Lemons That Are Deleted And Spherical
01:08:05 E4 - Lamented Unravelling Machinery
01:10:46 E5 - My Wrong Control Group
01:13:46 F1 - All True Is Made Up
01:16:33 F2 - Love Order Vitrification
01:19:41 F3 - Minor Memory
01:22:25 F4 - Damage Starts
01:25:29 F5 - Deleted

Stage 4
"The test subject at this stage requires assistance even with quite simple tests. They begin to forget how the portal gun works, and will often sit in one spot for up to 5 minutes, blankly staring at a wall. Brain activity shows that the most promenent emotion is fear, inducing horrors, stress, despair, and confusions."
01:28:14 G1 - Transition Into Post-Awareness Stage 4
01:34:45 G2 - Stage 4 Post-Awareness Horrors
01:42:36 H1 - Stage 4 Post-Awareness Calm State
01:49:59 H2 - Stage 4 Post-Awareness Confusions

Stage 5
"The test subject is no longer capable of solving tests that involve more than a button and a cube. They fail to recognize what a portal gun is, much less what it does. Tests are either solved at random or during brief moments of clear brain activity. The subject can barely understand advice given to them. Brain activity shows a slow decline from very high levels to almost nothing at all."
01:58:31 I1 - Stage 5 Post-Awareness Horrors
02:06:07 I2 - Stage 5 Post-Awareness Confusions
02:13:44 J1 - Stage 5 Post-Awareness Calm State
02:21:12 J2 - Stage 5 Transition Into Emptiness

Stage 6
"The test subject cannot perform any science."
02:28:57 K1 - Stage 6 Emptiness
02:36:26 K2 - Stage 6 Emptiness
02:44:04 L1 - Stage 6 Emptiness
02:51:51 L2 - Stage 6 Transition From Emptiness
02:55:09 L3 - Stage 6 Terminal Lucidity

So yeah, I've made this in the past month, with a big break between awareness and post-awareness because i had no idea how to do it. But I managed to learn FL studio and used it for like 90% of post-awareness so that's nice. Anyway, huge thanks to RubyPiec. She helped A LOT with teaching me FL and vital, and also with general feedback on the project. I'm actually collabing with her on a similar project, which will hopefully get finished sometime in the future.

And, finally, I don't own any of the original samples used in this video, all credit goes to valve corp.
