A sound recording is a reliance on a series of sounds that does not go with an audiovisual work. Copyright in sound recording is more limited than copyright in other works- it includes the right to perform the work to the public, but only using a “Digital sound recording”. Performing the sound recording in public in an interchangeable manner does not involve the copyright in the sound recording.
When a sound recording is conditional on a musical work, several uses of the sound recording include the musical work. In such instances, if a license is required, it must be obtained from the rights holder of the work.
