How to Catalog Sound Effects for Sound Libraries

By SFXsource

Once you have recorded a large amount of raw material and then edited this material into a batch of finished sound effects it is time to associate data with these products so that you can submit your library to distributors. This data is generally called metadata and gives potential licensees information on pertinent characteristics of each sound in your library. Main categories of data that have proven to be useful in my own catalog are discussed below.

Initially you want to pick the right format for listing your metadata. I have found that .xls projects and the most requested format for metadata which assign each sound a row and each category a column. This type of document, as opposed to a text file, will let you search your sounds easily in the future according to each characteristic.

1. Broad categories should be used for the first Main Category column such as Animals, Machinery, and Vehicles. Be as minimal as possible in picking the main categories for maximum simplicity and organization.

2. The next column, Sub-Category, should divide each main category into more specific types such as Vehicles:Cars, Vehicles:Trucks, Vehicles:Watercraft.

3. For excellent organization from the beginning, create a SKU number for each sound sample as you make then that begins with three unique letters, such as a personal acronym, and 5 digits like SFX00001_CarHonk. The sample which follows will begin with SFX00002 and so on giving each product a unique name. This SKU method is superior to alphabetical organization, especially if you record multiple versions of bird chirps, for example, over a number of years.

4. The Title is a friendly title to be displayed for the potential licensee such as Dog Bark 1.

5. Since shorter sound effects are generally worth less than longer sound effects it is important to include the Time Length in your metadata so that interested clients know the length of each sample they might license.

6. Information under Track Info can be written, for example, as 48k 16bit Mono .wav which specifies the quality of each sample by providing the sample rate, bit rate, mono/stereo info, and file type.

7. Keywords are very important in letting potentials buyers find your sounds and should not be ignored. They should contain the plurals of the sound, associated sounds, phrases, and even misspellings such as dog, dogs, dog bark, dog barks, bark, barks, dog pack, pack, wolf, canine, wolves, canines, barck, barcks.

After successfully organizing your sound effects according to the seven above characteristics you can market and submit your library to online distributors for profit through licensing.
