Abstract : This study presents an evaluation of the disturbance caused by audio latency in a DJing task. An experiment was conducted, during which subjects were asked to synchronise one piece of music to a reference piece of music using a common DJ interface. Synchronisation was performed by adjusting the speed of one of the music pieces to that of a reference piece of music and time-aligning both pieces. Latency was introduced between the interface and the audio output, varying between 0ms and 550 ms. The average synchronisation time was estimated as a function of subjects, Beat-Per-Minute difference between the pieces of music, and latency. Results showed that for trained DJs, synchronisation time increased significantly above 130ms of audio latency, whereas for naive subjects, latency had no influence on the synchronisation time.
