Playing multiple sound files on multiple output devices simultaneously with a Raspberry Pi

Devon Bray was working on an art installation project with Sara Dittrich. The requirement was to play 8 different sound files out of 8 different loudspeakers and to synchronise them all. For this, Devon used a Raspberry Pi connected up to multiple amplifiers via a USB hub. He’s done a video walk-through of the project, which can be seen below, has blooged about it here and uploaded his code to Github here.
