Sound Design - Iron Gates

The target of the session was to create sounds to be attached to the moving iron gates within the level.

The main actions of the gate were broken up into the following components 

• Sliding up/open (3.8 seconds)
• Fast close (3.8/4 seconds)
• Fully opened
• Fully closed

These actions were then synthesised by combining my pre-recorded audio samples. Combinations of a mechanical cog driven lifting device and metallic scrapings were used to mimic the doors movement grinding the stone. For the faster close motion this was edited to play back faster without damaging the pitch. For the impact sound of the door coming to a stop (open and closed) a number of layers were added together including metal and stone impacts on various objects.

For each movement sound different variants were created to minimise repetitive sounds during gameplay, such as separating some of the components that make up each full sound. These were then imported and tested in UDK using the 'Sound Cue' editor.

The next step will to attach these sound cues to the moving gates for further testing.
