AudioAlign - Synchronization of A/V-Streams Based on Audio Data

Abstract

Manual synchronization of audio and video recordings is a very annoying and time consuming task, especially if the tracks are very long and/or of large quantity. If the tracks aren't just short clips (of a few seconds or minutes) and recorded from heterogeneous sources, an additional problem comes into play - time drift - which arises if different recording devices aren't synchronized. This demo paper presents the experimental software Audio Align, which aims to simplify the manual synchronization process with the ultimate goal to automate it altogether. It gives a short introduction to the topic, discusses the approach, method, implementation and preliminary results and gives an outlook at possible improvements.
