807.2 (B) Sounds Accompanying Audiovisual Works Distinguished from Sound Recordings
There is a legal distinction between the “soundtrack” of an audiovisual work and a “sound recording.” The statutory definition of a sound recording specifically states that this category does not include “sounds accompanying a motion picture or other audiovisual work.” 17 U.S.C. § 101. Thus, when registering a claim in the soundtrack for an audiovisual work, the applicant should state “sounds,” “soundtrack,” or “sounds accompanying an audiovisual work” in the application, rather than “sound recording.”
For further information concerning sound recordings, see Section 803.
