This file describes how I replaced some of the sounds in DOOM with
sounds digitised from the Aliens movie. The sounds I used can't
be uploaded for copyright reasons. Digitising your own is easy and the
results are well worth it.

I bought a lead from Radio Shack to connect my VCR audio output to the
line-in socket on my Soundblaster card. Also needed is a WAV file sound
capture and editing program. I used a shareware windows program called
Noise Master, obtained from a shareware collection CDROM. I believe there
are a number of shareware WAV editors available.

You also need a program which allows you to replace the sounds in the
Doom WAD file with your own digitised sounds. Originally I used one from
DSEDIT.ZIP in this library. I now prefer a more recently uploaded program from
DMAUD.ZIP, also in the library.

Using the WAV capture/edit program I digitised sounds in 5 or 10 second
chunks, then edited them down. You need to make sure that the sound starts
at the place you want. DSEDIT and DMAUD truncate the sounds to the right
length as they replace them.

Below I have reproduced a partial list of sound names obtained using DMAUD. 
Those sounds not listed were not replaced. Note that the chaingun doesn't
have a seperate sound, it is just a rapid repetition of the pistol sound.
I digitised at least 30 different Alien sounds, hisses, shrieks etc. so that
I could replace most of the monster sounds in Doom. There are many sounds of
mechanical doors opening and closing in the movie which you can use to replace
the Doom door and lift sounds.
