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

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.
