Audio Modding / AKAO converter for sound effects - FFIX
« on: 2017-06-19 14:41:05 »
I'm trying to deepdive into the FFIX sound system (only the soundeffects not the music) as it could be rather easy to then switch out the sound effects from the Steamversion by custom made ones or the original from PSX. They're stored as AKAO on the images in the PSX Version and are stored as akb.bytes in Steam.

Maybe someone out there is smart enough or has more insight then me on AKAO files (and yeah start laughing as mine is almost at 0 ^^).
I want to know if there's a possible solution for converting AKAO files into finished wav/mp3/ogg.
There's a sequencer for the music but not for the soundeffects and I GUESS that everything is packed directly in the AKAO file itself rather than using an external sequencer from the PSX itself.

I could open them with this little tool: and see that there're two samples stored in the file and I was also able to convert the two samples into wav's samples. And it also displays information like Sample Offset, Loop Point etc...
What is missing, when I convert the samples, obviously are all the information around this two samples. What sample is played when and what effect needs to be applied.

Here's an example from the PSX Version:
The file contains two files and a folder.
The 0 is the AKAO File and the akb.bytes is the steam version (just drag and drop into VLC, it plays without problems).
The Folder contains the two samples that I've extracted from the AKAO file.

On the music part I tried using a psf psf file from the battle, and it could also be loaded by vgmtrans. It had the same 36  samples in it and with the help of tirlititi we could match that to the specific index/music from the steam version. So, in theory, there would be no guessing what will go into what file (as of now). The psf also contained the whole sequence.

I HOPE (!!) there's maybe a way to extract the whole sound effect in a finished state somehow from the AKAO files.
The Thread could also go into tools, but as I ask specifically around the AKAO file I'm good with either subforums. =)

I also asked in the modding subforum for FFIV:

Is there a tool that can unpack the resource file and repack them back?
I want to mess with my graphics pipeline to get rid of the big pixel/3DS look of the textures.

I couldn't find anything so far. :/

At last someone released a partially working version of the scaled Battle GUI.
GDI gave the permission to share it her as well (and maybe spread the word so people can finish his work).

I'm not the owner and or maker of the mod and I also couldn't test it as I don't use Memoria as of now.

It's getting hot in here, so take out all your cloth... well...
I filtered all the NPC's-, weapon- and battle background textures.

Let's make this Game more awesome! :D

Here are comparison shots:

Just unpack the 7z into your streaming assets.

If you've downloaded the old version, here's a temporary fix so the overworld stuff is vissible again.

Known Issue:
Worldmap model texture seem to be broken like Zidane and the vehicles (download the temp fix from above).
Characters don't blink. I'm investigating this and will release a patch ASAP. Sorry for all the inconveniences!

Hi everyone.
I've started on a Backgrounds replacement mod for FFIX for quite some time now and I'm finished around 50% right now.

Here's a quick video of an early WIP.

And yes, I've started a discussion on the steam forum as well:

The mod will be compatible with Hades Workshop and I'll try my best to implement it in Memoria as well.
Everything is going smoothly, still I can't give out an ETA.


Mod released! :D (Version 1.1) (csharp.dll file)


- Backup in your FFIX install directoy under "StreamingAssets" the bin files p0data11 till p0data19.
- Backup in x64\FF9_Data\Managed the Assembly-CSharp.dll file.
- Download the 7z and unpack it directly into you Final Fantasy IX install directory where "StreamingAssets" and "x64" sit.

Play! :D

If you don't want to use it anymore just copy over the old bin files as well as well as the Assembly-CSharp.dll.

I know Meru is working on the Backgrounds, too. As he's using a complete different tool set that I'm and we also have other ways of implement the mod, we're not collaborating in any way so please don't ask.
