What kind of audio or sound would not involve copyright disputes?

Normally, any audio or sound would be involved in copyright disputes because it could be considered a musical composition. However, there are some special circumstances that may exempt certain audio or sounds from copyright disputes: Public copyright: Some audio or sounds may have been declared public copyright, which means they are not protected by copyright. For example, radio broadcasts, television signals, internet music, and so on. 2. Citing copyright: If you quote someone else's audio or voice without indicating the source, it may involve copyright disputes. However, if the quote was from a copyright-protected work such as a movie, television program, music recording, etc., and the number of citations was not large, it might be allowed to be used. 3. Use with authorization: If certain audio or sounds are authorized by others, they may be exempted from copyright disputes. For example, if the audio or sound of certain novels, comics, games, etc. was used by the authorized party, it might not involve copyright disputes. It is important to note that even authorized audio or sound must comply with the terms and conditions of the authorized party. Otherwise, copyright disputes may arise.
