I was the audio manager for the handheld versions of this game and created sound effects and oversaw the entire games audio processes.
This is the blurb for the game taken from the developers website:
The Battle is Building! Based on the last three Harry Potter books and final four films, LEGO® Harry Potter: Years 5-7 takes players through Harry Potter’s heroic adventures in the Muggle and wizarding worlds. From Privet Drive in Little Whinging to Diagon Alley, Hogsmeade and Hogwarts, players will encounter new faces, new challenges and more magic, preparing them for the ultimate face-off with Lord Voldemort!
