I worked a little more with the sound replacement for left4dead. It is tricky as the audio engine of the game is modified and kinda different than the other valve games. So far I’ve had good results with the pipebomb and shotgun.
(DEMO)
Basically, I wanted the pipebomb to sound more..pipeish, like it is made out of a tube. A tube was used with high pressure air throwing a sponge out to get the thump sound.
Also the the commentary said the sound of the pipebomb was suppose to be high pitched and attracting the infected. I didn’t find the original sound to be anywhere near as high pitched and attracting than ripping apart the surviver and hear her\him scream. So I remade the “beep” by mixing hawk calls and high pictched alarm sounds and adding a echo. The sound is kinda scary in itself.
