Sonic CD Beta loops extracted from ISO

www.dropbox.com/s/xxjwz4rn6jz...
Almost every video, if not all, here in youtube with the unused audio loops from Sonic CD beta are VGM rips. IMO the original sounds from inside the ISO has much better quality so I have decided to post here it.
Also, i know i have not been too active, and i will probably stay like that for a while :( sorry, what happened is: Recently the sonic 1 beta was found, and i got super excited with that! but one of the things that mostly makes happy, is that a labyrinth background recreation i was doing in 2019 was getting super accurate to it.
I have a project called Sonic 2 Complete that consists on trying to restore all the levels, it made me feel very confident to finish this project so i'm currently focused on it! But it does not mean i will not post anything, if i get super inspired to make a new remix or something like that i will post.

I have remastered these. kzbin.info/www/bejne/foWYm5d3bKeNqLc

nice work!

[@user-ls8pd1pz3h]

Thats the highest quality version of 1:09 ive ever found

[@NukeTheOG]

Hearing these loops probably makes me think they were used in level transitions or time travelling transitions, like a loop to introduce you to a new stage. I wouldn't see any other reason on why they exist and go unused

[@CollisionChaos]

I think they were supposed to make the songs loop. I mean, in sega cd all the time the song fade out and restart, i think they wanted it to play non-stop, like the other Sonic games.

[@NukeTheOG]

@@CollisionChaos that too, but it would also be cool as a stage transition

[@daisukedoi9284]

@@CollisionChaos That makes sense considering that's what the Whitehead remake would do

[@ultra64dx77]

These would make perfect ringtones

[@DeevDaRabbit]

Thank you for uploading these. Now we have them in their original quality without upsampling, which means I can remaster them.

[@TheMurtdragon]

There's what sounds (to my ears at least) like a few instrumental differences between these and the final versions of the tracks (Wacky workbench bad future for example). Is it possible that some of these are glimpses into earlier versions of the tracks where the instruments and their paratemters werent finalised and ended up being changed for the final version?

[@CollisionChaos]

That would make sense. In stardust speedway present, there's a conga sound that on final version is a TR 808 cowbell aparently. Or they were trying to make the songs more variated? Maybe we will never know it :( At least not until we get more music prototypes from Sonic CD.

[@k-leb4671]

The Metallic Madness one is noticeably slower than the actual track. So my guess is that they are a glimpse into previous versions of the music.

[@DamianOsart777]

You can hear the complete tracks with this parts in Sonic CD Restored

[@k-leb4671]

I can't believe Sega has never released these bits. Sonic CD got an official soundtrack album and they're not even there. It's ridiculous.

[@adre2194]

The official release on Spotify is horrendous. Some of the songs literally fade out before looping.

[@atorniyk]

@@adre2194and the past ones are so compressed it’s hard to hear anything

[@YgorG]

Cool to se them extracted directly from the rom

[@lukabogavac5772]

These loops were intended to loop the songs, but were removed from the final game simply because it was too difficult to get the timing down.

[@AnthonyVCL]

I know this is easy to recognize but i got crazy when i heard the metallic madness present loop, it's so cool to know the intro for the past theme was supposed to also be in the present theme

[@CollisionChaos]

Yes!! i love so much this sequence. There's a fun fact: the same sequence was used in the final version of the song, playing together with the piano! but is pretty hidden, is super hard to listen

[@nolemhurb527]

tbh I kinda do like when it loops I've honestly never heard the loops before.

[@MorrisMusic]

Hello! To me personally, the VGM rips sound better than these files. If I recall correctly, the loops were not Redbook audio, unlike the Present, Good Future, and Bad Future themes, so they could play on loop as the Redbook tracks were being reset, which would be why they get ripped as VGM files. Could you maybe elaborate on this? This is quite confusing to me^^ Especially because these sound lower quality to me.

[@CollisionChaos]

Thanks for your comment. And yeah, those sounds are not redbook tracks, they're pcm sounds, AFAIK they're meant to make the songs play without a stop/fadeout at end, but this idea was scrapped, aparently because the quality difference which would sounds a little weird, there's various people who tried to do that with the VGM rips/WAV rips but it really sounds weird. The pcm chip add some higher frequencies on the sounds that ends up making it sounds higher quality, since the wav rips lack those higher sounds. To me, the reason why I personally prefer those is because the VGM rips has some artifacts that does not existed in the original sounds, and also did not existed in the CDDA songs, so the wav rips basically sounds closer to the CDDA songs, but at lower quality. So to make it simplier, IMO: VGM rips -> higher quality, lower similarity with CDDA songs WAV rips -> lower quality, higher similarity with CDDA songs

[@MorrisMusic]

I see, thanks!

[@DeevDaRabbit]

@@MorrisMusic I can explain this. They sound better because of interpolation. He forgot to apply linear interpolation to bring out high frequencies.

any idea how the synths were made in the MMZ part at 1:09?

i think could be roland jd 800 fantasia layered with something else, i just don't know exactly what :(

[@lowercase7455]

do you know which drums and bass were used in the You Can do Anything song?

[@CollisionChaos]

I don't know about the bass. Some of the drums sounds like TR-909 for me, probably sampled, maybe from the Goldmine.

[@NewtubeWorldYT]

Hey there, I actually heard these beta loops in the 2011 Mobile Port, and the multiple uploads of the songs in the 2011 Mobile Port, were they always there?

[@CollisionChaos]

This game is from 1993. The original version of it was supposed to have the loops, they would makes the songs play non-stop, like happens with the games that comes before Sonic CD (Sonic 1 and 2), as well like the past tracks. However due to the poor quality of the feature (since the loops had to be stored in lower quality) they decided to cut the idea. In the newer port/releases they decided to put the idea back, however they losted the original uncompressed loops and only had the low quality ones, that's why it did not sounded much good.

[@NewtubeWorldYT]

@@CollisionChaos After I commented this I found out the beta loops were discovered in early 2011 (or perhaps an earlier date I don't know about), which I imagine was before the mobile port was released giving them enough time to implement them into the game.

[@diarmikelly4060]

​@@CollisionChaosI thought they couldn't get the timing right for the pcm loops. Also I'm pretty sure they were originally meant to be cdda loops but there wasn't enough storage or something, I could be wrong.

[@testingtesting4458]

I'm convinced that R8A and R8D's names were mistakenly mislabeled in the files. Sounds obvious that they're switched imo

Those loops are pcm sounds that aparently were meant to make the CDDA songs loops instead of having a fade out.

They were removed in the official release from 1993. I don't know much details about different released that were made after that.

[@maxrichards5925]

@@CollisionChaos Oh alright. I think these were removed in the 2011 rerelease but I could be wrong

[@CollisionChaos]

@@maxrichards5925 They existed in the prototype version, but when they released the final version in 1993 they removed them. I don't know if they ever said why, but it's probably because some technical issues about them. The start of these loops don't work with the end of the songs, and the start of the songs don't work for the end of loop. It creates a incosistency on the sound that don't allow the loops to be properly used. That's one of the problems. The other one is that the loops are stored on a much lower quality, with some being in stereo and some being mono, while the songs are always stereo. There's also some instruments that are different in the loops, or even different BPMs. These tehcnical problems were most likely the reason the loops had to be cut.

[@AuntieAliasing]

If i'm not wrong, they exists in final version of game, although they're not used, that's why i did not included them, but you're right, i should have included it, sorry!
