Editing your raw audio recordings into professional quality sound effects is the step that takes place after the initial recording period. Hunt down an audio editing software that has eqs, the ability to cut audio, normalization, and fade in/out capabilites. You may use either a freeware readily found online or purchase one of the many digital audio workstations (DAW) available on the web.
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. 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.
5. Mix down a 48k 24bit stereo .wav file to be used for video productions. Such 48k 24bit stereo files earn the most money as they are valued by video editors and producers for their higher quality.
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.
A little knowledge of the ins and outs of audio editing combined with the above tips will allow you to easily create professional sounding effects that can be licensed time and time again by multi-media editors and producers.
