Soundworks have released a video detailing how the sounds of Black Swan were achieved.
Craig Henighan has worked with director Darren Aronofsky since Requiem For A Dream (2000) and his work on this film (as sound designer, supervising sound editor and sound re-recording mixer) is a key element of why it works so well.
