How a song changes the track

[criminalzerg]

Whoa! It turned right upside down? You have to post that song! I just gotta see this with my own eyes.

I saw your post and had to register to tell you a song that I found it happening in.

I saw it happen on Devil May Cry - Devils Never Cry (Off the Devil May Cry soundtrack =P) near the end. But for some reason it only seems to show up in Freeride, so I don't know what that means. Maybe they load different tracks? O.o

I've done some minimal research on the subject, and come up with some interesting results.

• Two of the same song with different ID3 tags will be different in some way. I had two of the same song with a different ID3 tag (they're produced in Audacity, so I'm not cheating or anything similar), and the twist I produced was removed in one copy. The actual song was exactly the same, though.
• File location seems to change the song a bit, too. One song began turning to the left, while the exact same song, ID3 tags the same and all, turned left. However, the blocks were exactly the same. I do not know if that's because I exported the file again to a different directory, though. I didn't copy the file and paste it in a different location.
• From my observations of the wave I produced in Audacity, the twist occured just after the wave resumed after a bit of silence. It appears to be completely random, because a similar copy and paste of a the wave that produced it, when put into a different song, didn't give me the twist again.

Now here is quite an interesting concept. It's a square wave I made in Audacity, but it's not high enough of a frequency to hurt your ears (at least, it wasn't to me). It performs a twist right as the silence resumes towards the beginning of the wave. For unknown reasons, there is a ridiculous number of red blocks at the beginning, and with Double Vision, I was able to obtain the required points for gold within 15 seconds. In addition to this, the end, despite being rather "upbeat" to the game, is almost completely devoid of yellow and red blocks. It ends very abruptly, just a note.

steady beat makes the road go up and down.

BPM does traffic i think.

speed makes it go up and down.

the real one is the side to side and the barrel roll.

i did a barrel roll mid hill-climb during "the divine falsehood" by job for a cowboy. that was a....5...6 minute song so i dunno about the length idea. but then again you have to factor in speed.

i also did a roll in Schism by tool. i dont know what causes it, it might just be bending a note, or a really high frequency, or it might be something stupid.

I also got a roll in Schism, by Tool. Near the beginning of the song. I'll listen to it again see if I can find any reason as to why.

hey guys, just an update, someone said that the turns were length based, today i got an incredibly windy turn in a grindcore song by last days of humanity, all most of them in fact are really windy, go figure.

I had a song by The Flashbulb that was so windy, the ending of the track was actually in a position behind the beginning of the track.

I played this song called "Quasar" (I'm sure Stepmania players would be familiar with that song), and when it stops to fade to a calm about halfway into the song, Audiosurf produced a nice, very slow twist.

Do tell, name the song! Flashbulb <3
