How much sound you can use to be fair use?

Answer:
There is no predetermined amount of copyrighted material that can be used. Each case is judged by the planned use and its purpose.

US Copyright Law sets out for criteria that have to be considered before something can be determined to be "fair use"

  1. The purpose and character of the use, including whether such use is of commercial nature or is for nonprofit educational purposes
  2. The nature of the copyrighted work
  3. The amount and substantiality of the portion used in relation to the copyrighted work as a whole
  4. The effect of the use upon the potential market for, or value of, the copyrighted work
