[OPEN SOURCE] AudioAlign: Audio Synchronization And Analysis Tool 1.5.0

Updated version with prebuild binary finally out:

AudioAlign is a research tool to investigate automatic synchronization of audio and video recordings that have either been recorded in parallel at the same event or contain the same aural information. It is designed as a GUI for the Aurio library.

Use cases
AudioAlign has been developed for a research project with the goal to automatically synchronize audio and video recordings, recorded at the same time at the same event, e.g. a speech or a music concert. The idea was to synchronize all those videos taken from the crowd and combine them to

  • generate multicamera cuts by switching between perspectives (video),
  • create videos with full or at least better event coverage,
  • replace bad quality audio or video tracks with better ones, or
  • detect interesting moments (where many recordings have been captured at the same time).

For more, see the readme.
