HaloMods "Classic" Read-only Archive

Please oh please, i need help, i am making a mod, i have got the perfect sound for something in it...... HOW do i convert it to bungies ADPCM sound that halo pc uses?, i have looked all over the place, halomods, google, all that other stuff but i can just not find it, please help!

I do not know what audio format Halo PC uses, but on xbox-scene.com under the tools section you can find the XBOX ADPCM codec.

yes i know that but all the links are broken...
