In order to record sound effects for a personal or professional sound effect library one first needs a quality recorder. Personally I've tried all sorts of pricey gear and microphones throughout my sonic adventures only to discover that a solid $150 to $400 handheld digital recorder no larger than an old-school cassette tape box suffices to create sounds good enough for placement in any Film, TV, and media project. In addition, these units run on battery power and the recorded files can be dragged onto your desktop via USB.
You must make sure that any recorder you purchase records up to at least a 48k sample rate .wav file because audio for video is prepared as 48k. Any 44.1k samples you have would work fine on a CD but for DVD usage they will have to be up-converted to 48k which can result in "aliases," sort of sonic ghosts that compromise the quality of your recording. Also, 48k sound effects command a higher price on downloadable sites because their sound quality is simply better due to more samples per second of audio.
There are two basic types of sound effects that you will be recording: "hits" and "ambiences." Hits are single short sonic events such as a slap, gun shot, or dog bark. Ambiences are longer background elements such as ocean waves, restaurant environments, or playground noises.
In creating a library it is most valuable to have many of both types as they are both used in sound design. You will find that ambiences are the easiest to obtain, as you merely have to go to a new location such as a supermarket or post office and just stand there and record. Hits need a little more forethought and preparation such as collecting the items you'd like to record or stalking the neighbor's dog for that perfect dog bark.
The basics of recording a sound effect is literally as simple as hitting the record button. However, there are several tips to keep in mind in order to get the best recordings possible.
2. Record all of your sounds as "hot" as you can, meaning as loud as possible without overloading the microphone. You need to pull back from your source if you notice a red LED light on your recorder which signals that your incoming signal is too hot. Capturing the strongest signal without distorting is the goal.
2. Very loud sounds such as explosions or loud cheering requires that you purchase a 10dB pad which will allow you to record high volumes. This sort of pad lowers strong signals by 10dB and can be bought on the web for $20.
3. Keep background noise out of your recordings as much as possible without being obsessive about creating "the perfect" studio recording environment because positive and unexpected events can occur such as animal sounds or car noises. A good amount of background noise can be filtered out during editing and being to strict about your recording environment will slow your work down to a crawl.
4. Keep your microphone out of the wind while recording by standing strategically behind wall, trees, or parked cars because wind hitting the head of the microphone will compromise your recordings. Through the editing process and by cutting lower frequencies you can often minimize wind noise but for the most part wind will render your recordings useless.
5. Keep background music from loudspeakers or live performances out of your recordings. Your efforts will be compromised if you inadvertently include music in the background, such as the music played in a restaurant. This music is copyrighted and if it appears in your ambience recordings you will be violating copyright law.
It is the hope of this author that the simple advice in this article will aid new sound effect artists in their efforts to create a worthy sound effect library. New articles on editing distinct sound effects from these recordings, categorizing these new sound effects, and licensing them are forthcoming.
