How to Edit Sound Effects for a Sound Effect Library
After recording a fair amount of raw audio intended for sound effects then it is time to edit these recordings. In order to edit your recordings well use an audio editing software that provides, eqs, normalization, fade ins/outs, and the ability to cut. Useful freewares can be found on the web and there are a plethora of digital audio workstations (DAWs) for sale that will allow you to edit.
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. The first step is to normalize each sample. This makes the audio as loud as possible by increasing the amplitude of the highest point on your recording to the highest point possible.
2. Second, use eq to cut out any unnecessary frequencies that may interfere with the quality of your sound. For example, you may have a recording of a bird chirp which also has an outside air conditioning unit humming mixed into the sound. To fix this problem, you can cut out all frequencies below 2,000 Hz which will take out the AC but keep the bird's higher tones.
3. Once you've gotten a strong and clean as possible .wav file find a good starting point that beings clean and create a nice ending either through a fade out or even better letting the sound fade out itself giving 1-2 seconds of air after the sound effect for the natural reverb to ring out.
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. By creating multiple versions of each recording you will increase the number of your products and thus the value of your library. For example, if you have a sequence of 20 firework explosions, create sound effects for one explosion, two explosions, five explosions etc while cutting and switching the order of explosions each time. Using this method, you can readily get 50 or more products from this one recording of fireworks.
6. Use pitch shift and other effects to create new versions of each sound to increase your number of products. For example, a burp sound effect could be pitch shifted down to create a monster burp sound and pitch shifted up to create a more childlike sounding burp.
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.
