Step 1: Create a GarageBand File
Step 2: FreeSound
We will be using www.freesound.org for all of our background noises other than Kung Fu' Fighting
Step 3: Background Music
For our scene we chose Kung Fu' Fighting by Carl Douglas
Step 4: Add Clip and Music
Next you will add your media clip and your audio to your GarageBand file. To do so, you just open the media column by clicking on the icon in the very bottom right corner and then you just drag whatever you want in your file all the way to the left of the screen.
Step 5: FreeSound Sound Effects
Now you will find whichever sound effects you want in your scene. Just search them in the top right search bar on www.freesound.org. Then scroll through the available sounds and choose your best one.
Step 6: Download the Sound
After you find your favorite sound you need to download it. Click on the file name and then once it opens to a bigger picture click the download button below and to the right of the file.
Step 7: Add the Sound to ITunes
After the sound downloads, find it in on your computer and open it in iTunes. From here you can change the name to whatever you want to help you remember.
Step 8: Add Sound to GarageBand
Open your GarageBand file and drag the sound over to the left column from the right column like you did for the background music. Keep doing this until you have all of your need sound effects in your video.
Step 9: Find Place to Add Sound
In the original video there are metal sounds and stuff like that. You want this to be as much as the original as possible which means you need to watch the original video and record each time a certain sound was made. For instance, there is a sword sound at 29 seconds in the original video so we will add our sword sound at 29 seconds also.
Step 10: Voice Overs
After you have added your sound effects you will need to record a voice over. To do this you click the plus in the bottom left corner and then click on the "real instrument" tab. After doing this click the red circle at the bottom and start talking. You can then move your voice over around until it is in a good position.
