Synchronized audio capture with an array of mobile devices
Nick Schaafsma, Ani Nahapetian · 2017
This paper presents and evaluates approaches for synchronizing audio recordings in a system composed of mobile devices and cloud technologies. The proposed peak alignment approach, which uses a high decidable sound as a reference signal, is evaluated against an approach using a global clock made available by the cloud provider. Both approaches are evaluated with respect to variation and distance from the source sound and the size of the mobile device array.
