You may need to reinforce certain sounds, a doorknob, a match lighting, whatever. There will be sounds missing because they were never recorded or are sounds for visual effects. Subdivide the sounds into components. A mas sive chandelier crashing through a heavy table is not a sound you will find in a library. Nor do you want to attempt to record it! And the production sound, if any, is no doubt the sound of a plastic chandler smashing through a breakaway table. Look for a heavy wood crash, a heavy iron hit of some kind. What else can be seen? Chains rattling, wood splintering, glass breaking, plas ter falling around the chandelier – you may need 10 tracks, but you can build the sound from components.
