How to Catalog Sound Effects for Sound Libraries

By SFXsource

The final step in organizing sound effects for submission to a sound effect library is pairing different types of data with each sound. This metadata, as it is called, lets prospective clients in on specific details concerning each sound. The seven most useful categories of metadata to be included in your sound effect catalog are listed below.

Finding the right format is the first step in creating your metadata document. The most frequently requested format for metadata is an .xls file with categories in columns and individual sounds in rows. Searching through your sounds according to File Name, or Time Length will be very easy if you use this type of format.

1. The Main Category column should contain broad categories such as Ambiences, Animal, Human, Transportation. Try to be as efficient in their use as possible in order to maintain a logical order to your library from the start.

2. The Sub-Category column is meant to break down each main category into various elements such as Animals:Birds, Animals:Dogs, Animals:Pigs etc.

3. If you associate a SKU number of three letters unique to you, such as your initials, and five digits such as SFX00001_DogBark with each sound effect upon their creation your sounds will be perfectly organized. The sound to follow the above example would begin with SFX00002 and so on which assigns a totally unique identity to each sound. This numbering system alleviates confusion in the future should you have multiple Dog Barks and only organize them alphabetically.

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

5. A simple but significant bit of metadata is Time Length since long sound effects are usually priced higher than shorter sound effects and the buyer deserves to know how much sound they are getting for their money.

6. Track info stipulates whether the sample is stereo or mono as well as the sample rate, bit rate , and file type such as Stereo 48k 24bit .wav which informs the licensee about the quality of the sample.

7. One of the main ways that clients find your sounds will be by searching for keywords and thus your Keyword category is very important. Plurals of the sound, related sounds, phrases that include the sound, and misspellings can all help your sounds be found such as car, cars, vehicle, vehicles, car driving, driving a car, kar, kars.

The next step after cataloging your sounds according to the above seven steps is submission to online distributors for sale of licensing rights.
