Wakefield, Yorks., UK (October 30, 2009)--John Casali used a SoundField ST350 microphone to capture on-set surround ambiance during the filming of Sherlock Holmes, starring Robert Downey Jr. and Jude Law.
The latest filmed addition to the Sherlock Holmes canon, directed by Guy Ritchie and released in the US on December 25, is an irreverent take on the story of Baker Street's most famous fictional detective. Exterior filming for the film began in early 2009 in suitably old-fashioned locations in Liverpool, London, Chatham and Manchester, with second unit sound recordings being overseen by freelance sound mixer Casali. Casali's recent credits include two Harry Potter films and the most recent James Bond film.
Like all of SoundField's other microphones, the ST350 captures audio in the four-channel SoundField B-Format, an output-independent format from which phase-coherent audio can be derived in mono, stereo, M&S or 5.1 surround sound can be derived using proprietary SoundField processing, and all from a single lightweight, portable microphone.
"The ST350 has been brilliant for capturing the basic 5.1 beds that the post production guys use to build up the surround mix from scene to scene," explains Casali. "It creates very realistic soundscapes--sometimes I still can't believe it's all from one mic. I used the ST350 a lot on crowd scenes and in the Great Hall at Hogwarts on the Harry Potter films, and on Sherlock Holmes, it's been great for capturing the sounds of the period horse-drawn carriages on the streets."
He adds, "I use Altiverb a lot to capture the impulse response of acoustic spaces we're recording in, and the ST350 has been brilliant for that, too. Now, whenever we're working in a location with a recognizable acoustic, I take an impulse response, because you can use it to recreate the ambience later in post. It's very handy for realistic dialogue replacement in post production."
