How to make a .snt extension?

[ferryadams10]

Hey Everyone,

I have got a .ogg extension file of a voice which I'm going to use in the Story but I want to make the voice come from the person himself cause else it sounds weird. And the only way to do that is the command: PlaySoundAtEntity but you can only do it with a .snt extension so how to do it?

the .ogg file name= MathewPrison1.ogg
and this is what I've got till now. But I don't know if that'll be good. Cause I can't play it in the level editor.

<SOUNDENTITY>
<SOUNDS>
<Main>
<Sound File="MathewPrison1" />
</Main>
</SOUNDS>
<PROPERTIES Volume="1" MinDistance="1" MaxDistance="10" Random="1" Interval="0" FadeEnd="False" FadeStart="False" Stream="False" Loop="False" Use3D="True" Blockable="True" BlockVolumeMul="0.5" Priority="0" />
</SOUNDENTITY>

Please explain me ASAP.

Kind Regards,
Ferry Adams
