Kore o subete no torakku ni tsuika.sm64

これをすべてのトラックに追加.sm64 (Kore o subete no torakku ni tsuika, which roughly translates to add this to every track) is a scrapped sound file that can be found found in the deepest inner files of the July 29th 1995 build.

The file was originally inaccessible, but an anonymous data-miner has managed to unlock it and post it publicly in reddit. It is a 0:01 seconds long sound file made digitally in a strange tone. Those who have heard the sound have reported that it is oddly extremely satisfying and relaxing to listen to for long prolonged periods of time.

Further research has proven that this sound file is used in every single other sound effect and/or track in the build's files at least once; some distorted, some prolonged, some unchanged, and some manipulated beyond recognition. The same data-miner that breached through the files to recover the sound has managed to separate each one of これをすべてのトラックに追加.sm64 from all of the game's sound files, upon hearing them, and then comparing them to the versions that do include the sound file, the anonymous hacker reports that there is a vast difference to the emotional impact of the song with the sound file removed.

Along with the file, they published some of the songs in the beta build (none of them were uploaded by them, as they claimed that the tracks were already in youtube before the whole 'Every copy is personalized' craze.', with the sound file included; and several documents narrating his experience with each and every one of them.

Introduction.
Taken directly from the user's post in the now-deleted subreddit /r/marioisfuckingmessedupman, the subreddit had roughly any members and it was mysteriously taken down by the owner, who has now deleted their account as well, as well as the user who posted it themselves, too, has deleted their account.

Track 001: Wet-Dry World
The document reads as follows:"'Boy you think Wet Dry World in the fully released version? Get a load of this shit. It sounds like it's from an actual Resident Evil game or something like that, it's... stupidly out of place for a Mario game. It's anxiety pumping... I can't believe what players would've felt like if this was in most copies of the game...""これをすべてのトラックに追加.sm64's manifestation is perhaps one of the most notorious, it's a heavily distorted version of it, used to start and end the crystal, loud melody, it almost sounds like drums. When removed, the constant sense of anxiety and that something could kill you at any given second largely withers to the point where you're feeling much more relaxed""The track was speculated to be removed because it pushed the limits of the console way too much, it contrasted too much with the game's happy-go-lucky atmosphere, and because Wet Dry World was way larger. Supposedly, only the downtown section, but much more detailed and larger, you could freely access the higher buildings via changing the level of the water, there were also no walls, so the skybox would still be there... additionally, the skybox was supposed to be the painting in itself... so that's fun.'"EXTRA: In a reupload of the track to youtube (linked above), one comment (posted by the user Greenish) says the following, which seems to coincide with the original poster's claims:

Track 002: Mario's old voice samples
The document reads as follows:"'What is this? A Looney Tunes cartoon? Can't believe Nintendo were even considering Mel Blanc voice samples for Mario's voice, they went so far as to add これをすべてのトラックに追加.sm64 into the mix, too.""The usage of the file is practically unnoticeable, it plays a reduced version of about 0.36 milliseconds at the end of each voice clip, in an extremely subtle way, and heavily distorted, too.""If you remove the sound... something is strangely off, it doesn't sound as offputting as weird, some guy who's only played Super Mario 64 before could even mix it up with Charles Martinet's voice, if you ask me. It's amazing how the anomalous sound file can actually modify someone's voice.'"

Track 003: Dire, Dire Docks
The document reads as follows:"'This one... doesn't seem as bad, at first. It sounds fairly similar to the version that reached the final game, even if the level itself was vastly different. It gives off this feeling of false tranquility, not like Dire Dire Docks, with that, you know shit's about to go down at any second... but this one just makes you feel like you can sit down, relax... and suddenly ZASH, you'll be betrayed.""The usage of the sound is subtle in this one too, at the end of each note you can hear a small bup that barely lasts, that's the sound. It's fairly prominent.""Scary stuff happens when you remove the sound... it changes the song, not just psychologically, I mean entirely. It literally changes it to the final version, I've had the version with the sound removed and the final version compared several times, and I swear it's exactly the same song. This... sound, it has to have more to it, it can literally warp how the human ear perceives sound... and I feel like that's something Nintendo doesn't want us to know... this is like some CIA level shit right here man...'"

Trivia.

 * Although the original poster's account was deleted and therefore there is no confirmed way of contacting it, research on this strange phenomenon will continue, but done by users, who with this knowledge can analyze the beta music of the game and report how it sounds like with the sound removed.


 * By the file's name, it can be confirmed that higher ups at Nintendo forced the sound to go into every track of the build, until it was mysteriously removed for the final version.
