Tips for Recording a Sound Effect Library
One first needs a professional quality recorder in order to record sound effects that can be good enough to be used personally or professionally. Though there are many expensive options, a handheld $150 to $400 digital recorder no larger than a small digital camera will provide professional quality .wav files. Furthermore, many of these units accommodate up to 4 gigs of recorded audio with the use of a flash card and utilize a simple drag and drop method for saving the .wav files via a USB connection.
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.
You will need to record two distinct types of sound effects: "ambiences" and "hits." Short single sonic moments such as glass breaking, an explosion, or a light switch click are called hits. Longer recordings of background noises such as those found on a playground, at a train station, or in an airport are called ambiences.
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.
Actually recording each sound effect is a simply process that only requires hitting the record button. Though, in order to make the best possible recordings, keep in mind these several tips.
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. Purchase a 10dB pad that fits between your microphone and digital recorder will enable you to record sounds with high decibel levels, such as jet engines or weapons. The pad lowers the incoming signal by 10dB and can be found online 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. Protect the microphone with a windscreen or simply keep your recorder out of the wind by using physical barriers such as trees, walls, or even your jacket, because wind hitting the microphone head will ruin your recording efforts. Sometimes wind noise can be cut out during editing with a high pass filter and cutting frequencies below 200-500 khz but for the most part wind will destroy your work.
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.
