Azu: short answer: no. Just open SONIC3K.DS2 in Goldwave as a raw pcm file (22050Hz, 8 bit, mono) to find out what's going on.
The sound format (sample rate, bit depth, channels) isn't specified in that mini-header, there are only the file lengths in there, all the sound effects must be 22050Hz, 8 bit, mono, unless someone alters the exe file.

I'm already working on a pcm importer/exporter by the way, it should be ready in a couple of hours, stay tuned.

EDIT: also suggesting a split since I don't like to derail this music thread with discussions about sfxs.

Just had a quick look and @file offset 0xa47c of sonic3k.exe is a 1 byte value that selects the sampling freq:

0x00 = 11025Hz
0x04 = 22050Hz
0x08 = 32000Hz
0x0C = 44100Hz

angryzor, when will you stop being so awesome? :O

[MainMemory]

That's one of the parameters for the function I looked at to figure out the format.

Also late, but I've found a library that should let me convert pcm <-> wav.

Never!

... as far as I know, WAV is PCM with a small header attached.

[MainMemory]

Not all wav files are 8-bit unsigned 22050Hz Mono. This library can convert them.

Have a first version of Sonic & Knuckles Collection Sound Replacer


after I imported a file

I wrote it in a couple of hours (literally!) so it might have some bugs, but it seems to work fine.
Remember, all edits are cached, which means that you can import 9000 sound effects but they won't be effective until you click on "save", and you can discard all the changes by clicking on "revert".
It can read a description file which must be named "sonic3k.txt" and must be placed in the same folder as sonic3k.ds2; if it doesn't exist (or is incomplete) then the sound effects won't have a name in the list. Note that sfx 1 in the sound test doesn't seem to exist so be careful when you label them. The format of this txt is simple: number, "description" (one entry per row)

Have fun

EDIT: fixed a small bug. Redownload if you downloaded it before I wrote this line. Also forgot to mention that I open the file for exclusive access, so if you run Sonic & Knuckles Collection while my program is still running you won't hear any sound. You have to close my program first, and run Sonic & Knuckles Collection afterwards.
I also advise you to make a backup of the original SONIC3K.DS2 (not that it's hard to retrieve it on the internet, but still). Nothing should go wrong, but don't blame me if your SONIC3K.DS2 magically disappears and you don't know how to restore it

EDIT2: updated the pics

So... We going to get any love for BRSTM? It's the easiest of the VG streams to loop these days...

[angryzor]

0x00 = 11025Hz
0x04 = 22050Hz
0x08 = 32000Hz
0x0C = 44100Hz

Found out some more:
If this value is OR'd with 0x01, the PCM is stereo.
If it is OR'd with 0x02, it is 16 bit instead of 8 bit.

So... We going to get any love for BRSTM? It's the easiest of the VG streams to loop these days...

It _should_ be supported through the vgmstream suppport. Does it not work?

Oh. Did not see that. if that's the case then yeah, it should work. I'll have to test it later. If that's the case though I can literally whip up the whole Sonic 3 VGM set in a matter of minutes.

stuff

Basically, if I get what you mean:

0 11025Hz, 8 bit, mono
1 11025Hz, 8 bit, stereo
2 11025Hz, 16 bit, mono
3 11025Hz, 16 bit, stereo

4 22050Hz, 8 bit, mono
5 22050Hz, 8 bit, stereo
6 22050Hz, 16 bit, mono
7 22050Hz, 16 bit, stereo

8 32000Hz, 8 bit, mono
9 32000Hz, 8 bit, stereo
A 32000Hz, 16 bit, mono
B 32000Hz, 16 bit, stereo

C 44100Hz, 8 bit, mono
D 44100Hz, 8 bit, stereo
E 44100Hz, 16 bit, mono
F 44100Hz, 16 bit, stereo

This will definitely be useful if one plans to make a brand new SONIC3K.DS2 with high quality sound effects; personally I'd aim for format E since I feel it would be useless to have stereo sound.
I might easily incorporate a selector of some sort in a new release of my program, but I don't think it would be a good idea. Changing the format requires the user to reimport ALL the sound effects to get them to sound right, so it's not something that should be done lightly.

I love you so much for putting in BRSTM support. Gives me another use for the custom songs I downloaded for Brawl!

However, for some reason I can't seem to replace song #55 (which I think is the S&K credits medley) with anything, regardless of whether I add "intro_" before the song ID or not. All I get is silence when I try playing it.

EDIT: Never mind, I forgot about the bit in the readme about ending the INI with a new line to let the song register.

I like ADX better. Just as easy for loopping. Also, nineko, you're more awesome than I though. For the tool, and the avatar. The cat from Azumanga Daioh.

[nineko]

Thanks

By the way, I crossposted my program here since I felt bad to derail angryzor's thread in this way. Also with a separate thread I can update the first post, publish it on the wiki, et al. But not now, it's almost 3:30am and I'll have to be in my office at 9am, this is what happens when I start programming something I like :U

After a bit of hacking SADXsndSharp, I've made SKCsnd, which allows you to import and export WAV files.

Edit: updated, now allows you to change the audio settings to any of the formats in this post. To use it properly, you'll have to Extract All, start a New file, change the setting, then Add all the files. You'll also have to change the byte in SONIC3K.EXE.

Edit2: Wiki'd
