How to Edit Sound Effects for a Sound Effect Library
Once you have recorded a large amount of material intended to be used as sound effects, the next step in creating a sound effect library is to edit this raw audio. You will need an audio editing software that will allow you to cut, fade in/out, normalize, and eq your tracks. There are many professional digital audio workstations (DAWs) out there for purchase and also several useful freewares easily found on the internet.
First import all of your raw .wav recordings into the software of your choice. Try to import 40 or so for efficiency, though you may attack one at a time, and solo each track for editing which mutes all tracks except the one with which you are working. Now you are ready to edit your sounds and then bounce them into completed sound effects. The following points will assist the quality and efficiency of your work.
1. First, normalize each track before editing it. This function increases the highest existing amplitude of the .wav file to the highest possible amplitude, meaning simply that it makes the .wav files as loud as possible.
2. Secondly, some frequencies may affect the quality of your sound effect and you should use eq to eradicate these sonic culprits. A great sounding bird chirp, for example, may be compromised by an offending air conditioner. But, by cutting all frequencies below 2,000 Hz you can get rid of the AC and keep the lovely bird sound.
3. When your sound is normalized and cleaned up with eq find a clean beginning point to the sound and either create a fade-out or more desirably let the natural reverb ring out for 1-2 seconds.
4. Bounce your sound down to a 48k 24bit .wav file for video editing. 48k 24bit are high quality files that are valued by sound effect libraries and licensees who pay good money to use sound effects in their productions.
5. In order to increase your amount of products make as many versions of each recording as possible. For example, if a recording has a cat meowing 25 times, make sound effects with one meow, two meows, 5 meows, 8 meows etc. while changing up the combination of meows. This process will easily give you 50 or more sound effects from one sequence of cat meows.
6. Increase your content holdings even further by using pitch shift. For example, a person's laugh can be pitch shifted down to create a deep giant's laugh or pitch shifted up to create a little child's laugh.
With a little knowledge of audio editing, simply follow the above advice to transform your audio samples into professional quality sound effects for licensing in media productions.
