In Amnesia, sounds are read from .ogg files through another format called .snt. And these files are not sounds, rather just text files which tell the game what to play. If you navigate to the /sounds/enemy/grunt/ folder, you will find .snt's and .ogg files, such as these:
Code:
- amb_alert.snt
- amb_alert01.snt
- amb_alert02.snt
- amb_alert03.snt
Based on what I said prior, you can assume that amb_alert.snt will play the alert sound files. And yes that is correct. Open up that .snt file with your favorite text editor, and you'll see something like this:
Code:
<SOUNDENTITY>
<SOUNDS>
<Main>
<Sound File="grunt/amb_alert01" />
<Sound File="grunt/amb_alert02" />
<Sound File="grunt/amb_alert03" />
</Main>
</SOUNDS>
</SOUNDENTITY>
ALTHOUGH there are other things, they are not necessarily important unless you wish for them to be edited. As you can see, this will play these sound files.
This is where your Audacity files kick in. For now, make a copy of the "grunt" folder from earlier, and name it something you can remember. Then after that, from your new folder, feel free to delete whatever you don't want in there for capacity reasons. You don't have to worry about missing files, because the copied grunt will assume the role of a normal grunt's voices if there is no sounds here.
Code:
alert = when the grunt is chasing you
hunt = when the grunt is looking for you (like, you made a noise)
idle = when the grunt is walking or standing still, unaware of you
claw = when the grunt attacks you with its claw from up to down
launch = when the grunt attacks you like an uppercut
enabled = when the grunt is enabled via script
hit = when the grunt hits something like a box
leather = footsteps sound
notice = when the grunt spots the character
Once that is done, copy over your Audacity files in .ogg format to the new folder created. If you deleted it, go back to the original grunt folder and copy the amb_alert.snt file. Afterward, open it with the text editor and change the first few lines to suit your Audacity files:
Code:
<SOUNDENTITY>
<SOUNDS>
<Main>
<Sound File="<new_folder>/friends_voice01" />
<Sound File="<new_folder>/friends_voice02" />
<Sound File="<new_folder>/friends_voice03" />
</Main>
</SOUNDS>
</SOUNDENTITY>
You can add more Sound Files if you want, just keep them in the same format and between the <Main> and </Main> parts.
