It's hard to see, but the wave effect still exists in Sonic Adventure DX, it's just the lightning isn't applied to the vertices to really highlight the water level's given height.

In SADX the water just changes its overall height (moving all vertices at once - looks like jelly, kinda awful actually), while in SA1 it gets replaced on the go with a higher-poly model, where individual vertices shift in a wave-like motion. You can play SADX at 0.25x with Cheat Engine's speed hack to see it more clearly.

Basically this. There's now way that it's a wave in SADX. You can see this at the end when you land on the beach, it just flails up and down. Can anyone have a look? :v

I guess I must just be crazy because you're right. When I was reviewing my footage for the Dreamcast Conversion video I did, it looked like the wave effect was still there, but you're right, the water level just bobs up and down.

Finally done with Sound Overhaul 2. You can get the mod here.

Things you'll get with this mod:
  • All sound effects in the game (except Chao-related stuff) are replaced with SA1 Dreamcast sounds, which are generally of better quality
  • Dreamcast character voice clips
  • Many missing sounds are back! Including ambient noises and cutscene sounds
  • Overall, the sounds are slightly louder and more vibrant

Why didn't I replace the Chao sounds? Well, the Chao soundbanks are completely different between SA1 and SADX and, while some replacement is probably possible, I don't feel like going several hundred times through baby/infant sounds. I've never really been much into Chao stuff anyway, so if anyone wants to pick it up from here, I'll be happy to offer help and suggestions.

A few comments just to give you an idea of how much pain I had to go through for this whole sound thing:

  • There are 2 plugins for foobar2000 that can convert the ripped sounds to WAV. Both stumble on many (often the same) sounds, one (the more accurate one) just barfs out garbage and another produces defective sounds (clipping, DC offset etc.). I did my best to remove the defects, and in the most difficult cases I ripped the sounds from SA1 sound test using Demul. I had to normalize them to make sure they matched the rest of the sounds. Each plugin rips the sounds at a different volume and is totally random at interpreting the volume setting in the soundbank, so matching the volume between different rips was extremely tedious. On top of that, it seems like SADX has arbitrary volume settings for each sound, which complicated thing even further.
  • Even though I found a way to disable the reverb, some sounds actually required it. So I had to go through each of the soundbanks to find missing sounds, and rip them again with reverb enabled.
  • There were many volume issues, ranging from some sounds being too loud/too quiet, to audible clipping. Again, I had to make multiple rips (each ate around 5GB!) to get the best volume without clipping. Then I also had to play through the entire game to ensure the volume of each sound wasn't too loud or too quiet. Obviously that involved some arbitrary decisions on my end, and I corrected many sounds according to my personal taste, which others may not share, so I'm looking for some feedback regarding sound volume, which you can leave here. I also left some SADX sounds intact because they sounded better (higher quality) to me, but that was just 1 or 2 sounds. Still, I think I got pretty close to how it sounds on the Dreamcast.
  • I had to loop all looping sounds on my own. A program called LoopAuditioneer made it a whole lot easier, but there was a lot of manual looping involved, too. I swear I'm not touching that ever again.
  • SADX uses a positional audio system, which means that USUALLY all sounds are in mono except some background noises. However, there were a number of cases when a sound that was supposed to be in mono was in stereo (which made it too loud and interfered with other sounds), and vice versa (which made some sounds silent). The ripped sounds were all in stereo so there was no way to tell which should be converted to mono, and which shouldn't. I had to play through the entire game multiple times to find the sounds that were supposed to be in stereo, and those that were in stereo, but were supposed to be in mono.
  • Some sounds had to be recreated: the sound of dropping bullets in the cutscene before Chaos 0 and Zero's chest-thumping sound. Those may not be identical to their Dreamcast counterparts, but I tried to match them to the best of my ability. Also, I tried to change the pitch of the falling sound Sonic makes in the cutscene after Sky Chase 1 - this also isn't the same as in SA1, but a bit closer than the SADX version. I couldn't change the pitch too much because it started to sound choppy at some point.
  • SADX has a few sound issues stemming from using incorrect soundbanks - this had to be fixed in code, which is why a DLL mod is also included in the package.

So here goes my take on Dreamcast sounds. Was it worth the pain? I think yes, totally. First of all, I've always hated how the characters sounded in SADX, so getting their Dreamcast voices back made the game more enjoyable for me. Secondly, I think the sound quality has improved as a result. Here are some comparisons:

Jump sound:
SA1
SADX

Ringloss sound:
SA1
SADX 2004
SADX Steam (god this is awful)

These are just the first sounds that came to mind for comparison, but there are many more.

Anyway, I hope you like the new Sound Overhaul, and I would appreciate your feedback. Keep in mind that it doesn't fix some audio-related issues that are caused by errors/changes in the game's code, like sounds being cut off too early, or sounds being looped incorrectly when playing the game at a high framerate. Some sounds are also missing because the code to play them no longer exists (such as Sonic's "Whoa!" when being attacked by Knuckles in the cutscene before Chaos 4, or the rings that NiGHTS takes you through in the Casino pinball stage).
