I'm using Audacity. I'm having trouble of making a cactus sound effect when it gets cut off by the ufo ship. I would also like your opinion on how I can improve the sound effects applied on this video. Feel free to improve the sound effects but do let me know the techniques you used

i can't download from mediafire, can you link to an mp3 on hotfile? I can't change the file but I'll tell you how to fix it. I never really tried sound editing, but I've made techno music and gun sounds that were pretty good for the amount of effort it took. I also am an audiophile / re-encoding guru. P.S. Cacti make sounds??
