Advice on Recording Sound Effects for a Sound Effect Library
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.
Be aware, however, that any device you use must record up to at least a 48k sample rate because video uses audio with a 48k sample rate, not 44.1k. Any 44.1k samples you have will have to be upconverted to be used in a video production and this process always runs the risk of audio damage. Because of these potential problems with lower quality files, 48k sound effects are generally valued more by video editors and thus command a higher sale price should you choose to sell your sounds online.
Two basic categories of sound effects to be recorded are "ambiences" and "hits." Hits are single audio events like a burp, splash, or car horn. Ambiences are longer recordings generally between 30 seconds and 10 minutes that contain background sounds such as those found on city streets, in a hotel lobby, or a doctor's office.
Any quality sound effect library needs both types of sound effects so you should be intent on recording both types. Ambiences are the easiest to obtain because they require only being at a location, standing there, and recording. Hits, though, need more planning because you often need to do foley to get what you need or wait around at various locations for the right moment, such as visiting a new mother and her newborn in order to capture that perfect baby cry.
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.
1. When you record you want to have the loudest signal possible without clipping the microphone, called recording as "hot" as possible. If you notice a small red LED light lighting up during your recording then you need to pull back from the sound because your incoming signal is too loud. The goal is to avoid distortion but capture the strongest sound possible.
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. Wind hitting the head of your microphone will ruin your recordings so keep your recorder out of the wind by using trees, walls, or your body as a physical barrier. If you cut frequencies below 200-500 khz during editing you can get rid of some wind sound but usually your recordings will be ruined by wind.
5. Make sure that your recordings do not contain any live or amplified music from a third party. Your recordings will be useless if they include music from such sources. This music is copyrighted and without permission of the copyright owner it is illegal to use or license such recordings.
These tips are simple and meant to point an aspiring sound effect artist in the right direction toward the creation of a sound effect library for use or for sale online. Future articles will discuss the process of editing, categorizing, and marketing these raw recordings.
