I want to use certain sections of a sound effect.
Would this be a problem since I am not "synchronizing" the whole piece?
Since this is a game, the pieces of music are played one on top of the other. Does this count as "altering" the piece of music?
I am a computer science student with no legal or music background, so I am lost with most technical words.
