Manhunt sfx|.SDT and Headerless Raw WaveForm files

[JackKrowell]

Hello there, I'm looking for the voice sfx used in a hidden message, that plays out on the main menu screen for Manhunt PS2.

I have reason to believe that they could be stored in some files found within said game, under the name(s): "SFX0.Headerless Raw WaveForm, SFX0.SDT, SFX1.Headerless Raw WaveForm, and SFX1.SDT." Is there any way at all that I can extract/convert those 2 specific file formats to a playable audio format, such as wav?

Here's a shareable link for the folder containing the SFX files I'm talking about:
