Hi Guys, although this isn't a prop in the usual sense of the word, this does make a nice addition to props or your haunt in general. This is my first time posting a tutorial here, and wasn't sure if this was better suited on the How to section or the Halloween Music section. Please move to correct forum if need be. Hope you enjoy, and find it useful. OK, here we go.

Goal: To create the creepy voice effect much like in poltergeist

What You'll Need:
1. Audacity (Here)
2. Sound Clip you wish to alter
3. Gverb Audacity Plugin (Info here)


Step 1: Install Audacity and open the program. you will be greeted with a screen like this:




**Note** We will need to load the sound clip into the program that we wish to alter. You can load a clip that is already on your computer, or we can record on using our mic. for this step we'll assume that we already have a file on the computer.

Step 2: Click on File > Open > (navigate to your file, select it, and click open on the dialog box) Your audio file will now be in audacity ready to be creeped.




Step 3: This is the part we will be adding the effects. First, Click on Effect at the top middle of your screen. Choose the reverse effect. You will notice the audio changed. If you play it at this point, it would of coursed be revered... clever eh? ok moving on.

Step 4: After the Audio is reversed, we will go back to the Effect menu option, and this time we are going to select the Gverb option. (assuming you installed the gverb addon, I will touch on this after this tutorial) The Gverb Option window will be displayed here. This is the area where the main effect happens. I could go into detail as to what all these options mean, but theres really no point. Slide the bars until you get a sound that you like. for the purpose of this tutorial i will show you the settings i used for my audio that i altered.



Step 5: After finding a setting that fits your tastes, click ok on the Gverb window. You are now back to your audio file. At this point we will now:

Step 6: Click the Effect option one last time, and select Reverse again.

Click play. It should have a nice echo ghostly effect to it. Here are the audio files i used so you can get an idea of before and after sounds.

Before Alterations

After Alterations




Side Notes. Gverb Info(taken from wikki) GVerb is currently included in the 1.2.6 Windows release of Audacity, and with current Beta releases for both Windows and Mac. It will be underneath the divider in the Effect menu.

Alternatively, GVerb is also distributed as a separate download inside a suite of LADSPA effect plug-ins. This suite is available for Windows, Mac and Linux.

How to install: After downloading from the appropriate link above, the plug-ins should be installed as follows:

* Windows - Run the .exe installer and set the installation path to the Plug-Ins folder inside your Audacity installation folder. This installation folder is normally in your Program Files folder, so in that case install the plug-ins to:
C:\Program Files\Audacity\Plug-Ins.

* Mac - The plug-ins should be installed to:
/Library/Audio/Plug-Ins/LADSPA/ or
~/Library/Audio/Plug-Ins/LADSPA/.

* Linux - The plug-ins should be installed in:
/usr/lib/ladspa/ or /usr/local/lib/ladspa.

I'm a longtime Goldwave user, and I'm still trying to get this sound just right. I have Audacity, and will try your setup right away. Thanks for the screen shots - this makes it easy to see what parameters to play with. I already know where I'm going to use this effect. Many thanks!

I'll look for more add-ons, too. I wasn't aware of those options for Audacity.

I've been doing this effect for years..If you don't want to use Gverb, You can use Goldwaves reverb effect. Does the same thing, and you can just use one slider to preview the sound before applying effect. Some caveats regarding what kinds of sounds you can alter...the must not contain music, or echo effects. Some words that begin with hard sounding consonants like "K" or "P" don't reverb well, but still work. Although childrens voices work best, it works well with other pitched voices, such as the one djchrisbaker did for my ground breaker. He supplied the voice, I applied the "Carolanne effect" as I call it. It really is a cool effect, I'm sure you guys will get a kick out of it. Thanks for posting the how-to!

Sorry guys, youll have to give me until monday to update the audio files. I recently cancelled my rgiammaria.com domain and registered a new domain geared to halloween. I'll have the files back up and running sometime early next week. thanks for the heads up on this one.

Really beautiful effect, and so effective at creating the creeps. I'll have to try this when I have cleared enough room on my computer to download the program (which, unfortunately, may not be for a while:(). Thanks for the tips!

Gverb

Mornin' GDfreak,

I am pretty sure that GVerb is currently included in the 1.2.6 Windows release of Audacity, and with current Beta releases for both Windows and Mac. I think the Current version is 1.37 (but it is a beta which may contain errors) i would stick to 1.2.6 which is a stable release and can be found at: Audacity: Free Audio Editor and Recorder Download it and check i am pretty sure it's already included.

@ Zombie - the download is only 2.1 megabytes, which is super super small. you dont need alot of room or ram to run it. but i understand, ive had many a computer that i made wheeze its last lol

Good Luck, any questions let me know :)

Wow, at 2.1 MB I think I may have to download it anyway (yes this laptop is uttering a death-rattle but I'll squeeze every darn drop of "life" out of it that I can;)).
Though I may have to wait to play with the effect until after this semester is over (I may be cruel to my computer, but I still need it to last through May:D).

Mr Grimsley glad you liked it. you can really play around with it till you get the amount of echo and effect that you want. Try not to over do it though, because when played at a decent volume, it becomes kinda hard to understand.
